Why Collaboration is King at Fabtech 2019 with Dan Allford

Why Collaboration is King at Fabtech 2019 with Dan Allford

It takes multiple companies to make robot automation come to life in metal forming, fabricating, welding or finishing. At Fabtech 2019, Dan Allford  of Arc Specialties provided a picture of why collaboration and cooperation between companies in different segments of the industry is so important.

“People that come to this show typically come with a problem to solve,” Allford said. He went on to explain the role of a robot integrator in the process of creating a robot for a specific purpose.

“A robot integrator takes that robot arm and then adds the tooling, adds the software, and also adds the tooling to hold the part,” he said. “As you can see on this Fanuc robot, Fanuc built the robot, we added the seventh axis, we wrote the software. So we work very closely with our partners.”

Shows like Fabtech allow companies to stay up to date with what their partners have developed and find new ways to collaborate on putting these creations into practice.

Get a Preview of What to Expect from ARC Specialties at FABTECH 2019

ARC Specialties’ customers depend on us for the best in automated manufacturing systems and custom equipment for joining, cladding, and other applications. So, at FABTECH, we’ll be spotlighting four innovative products.

Surface Finishing Polisher

Robots have been in use for decades to move to fixed positions; however, some applications, such as surface finishing, require force control as well. We’ll be demonstrating our new approach to surface finishing at FABTECH, an inventive system which includes multiple components:

The Kuka LBR iiwa is a seven-axis force-controlled collaborative robot (cobot) that incorporates force sensors into each axis with a resolution of less than one pound of force. Combining superior 3M abrasives with Burr King belt sanders and polishing spindles, along with an experienced robot integrator that puts it all together and creates the code, the result is a cell that demonstrates force-controlled polishing on the belt sander slack side and wheel, with final finishing on a disk.

FlexFab™: Flexible Fabrication 3D Robotic Plasma Cutting Cell

ARC collaborated with KUKA, Hypertherm, and RobotMaster to create the FlexFab™: Flexible Fabrication 3D Robotic Plasma Cutting Cell, an integrated system that converts CAD models into a 3D plasma cut steel part, saving time and labor hours via precision control:

First, the RobotMaster CAD/CAM software generates the robot path. Then, cutting parameters are automatically generated based on part thickness via the Hypertherm Process Selection System. And with our proprietary touch work technique, part registration is accomplished before cutting. During the actual cutting, the ARC FlexFab software maintains the optimal torch to part distance, regardless of the torch angle, eliminating the need for a dedicated torch height control axis. And all robot axes use vector torch motion perpendicular to the part—a unique capability essential in the 3D cutting of complex parts. 

AI Pipe Welding System

Considered the most difficult welds to make, ARC Specialties previously declined jobs requiring full-penetration, single-sided, V-butt pipe welds since the joint fitup was never repeatable. A real challenge, these welds have traditionally only been completed by the most skilled human welders. However, labor such as this is depleting, so ARC decided to develop a product that could make these tricky welds, resulting in the Artificial Intelligence Pipe Welding System (AIPW):

Small enough to be portable while still allowing for full freedom of motion for both the laser scanner and welding torch, the AIPW incorporates the six-axis UR5 collaborative robot arm from Universal Robots A/S. Using a 2D laser, the AIPW pre-scans the root opening (gap), then uses the data to generate the robot path and welding parameters. Gap variations are compensated for with changes in oscillation, torch position, travel speed, and welding conditions. The UR5 positions the torch over a tack weld to start the arc, ensuring 100% root weld acceptance. Fill and cap pass programs are optimized to fill the groove using user-selectable weave or stringer bead welding techniques. Then, the AIPW uses the Miller Auto Continuum welding power supply to weld the root with Regulated Metal Deposition (RMD), and switches to pulsed spray for the fill and cap passes. This combination of Gas Metal Arc Welding techniques maximizes welding productivity while producing X-ray-quality, full-penetration pipe welds—all without the need for human labor. 

ARC 5 Infinity: Infinite Rotation Robotic Cladding System

If oil has a Sulphur content of 5%, it’s considered sour. Toxic to humans, this biodegradation produces hydrogen sulfide (H2S), generating atomic hydrogen than migrates into the steel matrix, causing sulfide stress cracking—a form of hydrogen embrittlement. The conventional solution has been to clad weld overlay all internal surfaces of valves and pipes with nickel-based alloys low in iron. Enter the ARC 5:

The ARC 5 Infinity is the next generation of ARC Specialties’ GTAW Hot Wire Systems, which can be found in hundreds of businesses around the world. While the first systems were simple turntables rotating the part while the welding torch clad the inner surface, as parts became bigger, we opted to leave the part stationary and rotate the torch instead. The ARC 5 combines our infinite rotation head with a Fanuc robot, resulting in a superior design purposely engineered to weld complex parts with intersecting bores.

Experience ARC Innovation at FABTECH

Be sure to visit ARC Specialties at FABTECH in booth B31019 where we’ll be demonstrating our Surface Finishing Polisher and Flex Fab 3D Robotic Plasma Cutting System, debuting the AI Pipe Welding System for the first time, and launching the next generation ARC 5. We look forward to seeing you in Chicago and ensuring you have the right equipment for all your metal needs.

The Roboticist Chronicles: Talking Tariffs, Subsidies, and Free Market Capitalism

The Roboticist Chronicles: Talking Tariffs, Subsidies, and Free Market Capitalism

Tariffs and subsidies are a hot topic at the moment, with global trade affecting the market each day. But who exactly are tariffs hurting and helping? Dan Allford, president and founder of ARC Specialties, delivers his perspective on this episode of The Roboticist Chronicles.

Allford, a proponent of a global free market, described how his boyhood job of selling papers ignited a deep appreciation for free market capitalism.

“Very early on I saw the connection between effort and reward,” Allford said, describing the beauty of America’s self-made-man economy. But when tariffs and subsidies make their way into the free-market Dan explained, “creative destruction,” occurs, upending the natural homeostasis of who survives in a free and fair marketplace.

“If you have an unlevel playing field, and that’s either subsidies or tariffs, either one distorts this field. And so what you’re doing is rewarding people that truly should have failed,” Allford said.

He elaborates with historical examples of trade between Brazil, France, Germany, and of course, China, giving examples of how tariffs and subsidies have handicapped industries that are now unable to survive without aid.

“We don’t need protection, we need opportunities to innovate,” Allford said, pointing to America’s naturally scrappy, competitive nature. At the heart of a growing economy is innovation, the natural push that keeps humanity at the forefront of technology, robotics, and mechanization.

Get to know Dan’s Darwinian economic point of view in this timely episode of The Roboticist Chronicles.

ARC Specialties Holds Class on Submerged Arc Welding

ARC Specialties Holds Class on Submerged Arc Welding

On September 10, 2019, at the weldingAcademy hosted by Bohler Welding in Sugar Land, Texas, ARC Specialties delivered a course on Submerged Arc Welding (SAW). The program was organized into three sections by Dave Hebble, ARC Specialties Technical Services Manager: Welding Process, Process Variations, and Wire / Flux Selection.

Although this process has been around for 80 years, SAW is still one of the most misunderstood welding processes. Dave began this class by discussing how this process works and how changes in welding parameters affect the shape of the weld bead. He dove into the influence of the welding current, welding voltage, travel speed, wire size, and wire extension.

View the presentation here!

Dave then discusses the common process variations: single wire, twin wire, tandem, multiple electrodes, one-sided welding, narrow gap welding, and electroslag strip overlay. By providing a recap of each process, he explains their details and different applications.

The class ended with wire and flux selection. With so many wires and fluxes available, it can be difficult to make the correct material selection. Dave discussed the selection criteria to help narrow your choices: application, parent metal chemistry match, weld performance, mechanical properties, AWS classification, code requirements, and third-party witness (ABS or DNV).

ARC Specialties is proud to share their knowledge of SAW and help welders expand their skills in the field. From the original specification, to the delivery and setup of a custom system, ARC Specialties works to generate excellent products that meet and exceed production needs.

The Roboticist Chronicles: Lockheed’s “Skunk Works” Business Philosophy in Practice

The Roboticist Chronicles: Lockheed’s “Skunk Works” Business Philosophy in Practice


Every business approaches how they work in a unique way. Each has a philosophy and culture, and each approach has it’s merits; some more successful than others. But why? On this episode of The Roboticist Chronicles, we talked business philosophy with Dan Allford, president of ARC Specialties.

ARC Specialties has sound technology, but they still need a corporate structure to execute it. Allford, who had years of technical training but only one business class, wanted to create something that worked at ARC Specialties. Instead of reading books on the latest fads, he followed people. And one that inspired him the most was Lockheed Martin’s founder Kelly Johnson and his Skunk Works philosophy.

What is Skunk Works? It is the name of Lockheed’s Advanced Development Program and has become a business philosophy applied to many, many industries. It’s based around creating groups within an organization and allowing them a high degree of autonomy.

“What I appreciate about Johnson and Skunk Works is that it’s about empowering project managers and giving them the ability to control their destiny,” Allford said.

While working in automation and robotics, you might assume that it isn’t people-centered. The human portion, or the “team,” is the most significant part according to Allford.

“We reward people based on what they create, not who they manage,” he said. “A good manager hires the right people, gives them a task, tools, resources and lets them do what they do best.”

That’s how ARC Specialties runs, stripping out layers of bureaucracy and focusing on the task. It also allows the company to remain nimble in the marketplace and exchange ideas. It even allows Allford’s employees to tell him when he’s wrong!

What is the Best Method for Preheating 4130?

What is the Best Method for Preheating 4130?

Widely used in the oil and gas industries, AISI 4130 steel is quenched and tempered for strength and other specific properties. However, once the material has been welded, the properties of the heat-affected zone are adversely affected. To lessen the effects of welding on 4130, preheating is an essential requirement of the welding procedure.

ARC Specialities conducted a study using a single valve body to compare induction, resistance, and direct flame preheating methods to determine the most effective and efficient preheating technique for 4130 steel. Maintaining the industry minimum of 500˚F for one hour, as well as the temperature drop for one hour with no additional heat input, the test also recorded the amount of time required to setup and tear-down each heating method, the time to preheat to 500˚F, and the time difference between inside and outside reaching 500˚F.

The Results

  • Preheat Time – Induction produced the best results with both the inside and outside of the valve reaching 500˚F in 0.6h, with resistance heating requiring the greatest amount of time to achieve through-thickness preheating.
  • Setup and Tear-Down Time – The flame method required the least amount of setup and tear-down time, only taking 0.25h for each, with resistance requiring the longest time cumulatively.
  • Energy Efficiency – Based on energy generated and consumed and total energy used, recording kilowatt-hours (kWh) for resistance and conduction and pounds of propane used for flame, the induction method was the most efficient, using 21.5 kWh and 73,000 BTU with the smallest temperature drop once heat was removed. Flame preheating was the least efficient.
  • Safety – Based on the amount of handling and potential hazards, induction was found to be the safest method of the three, while propane was found to be slightly more dangerous than resistance.
  • Cost – Based on the cost of labor ($65/h), electricity ($0.064/ kWh), propane ($0.652/lb) and personnel usage, induction heating was found to be the most efficient use of the operator’s time, using the least electricity and having a very fast uniform heating pattern, costing $150.34. Resistance heating was found to be the most expensive, costing $287.57.

Conclusions and Recommendations

Based on the study, the induction method was found to be the best in most categories. While the cost of induction heating equipment is greater than that for either the resistance or direct flame method, the efficiencies offered will offset the added investment and create a safer working environment, optimizing both productivity and quality.

From a Small Garage to Big Success: The Story of Arc Specialties

From a Small Garage to Big Success: The Story of Arc Specialties

From its inception in 1983 to now, ARC Specialties has become a case study in the growth of an American entrepreneurial endeavor. Company President Dan Allford took the business out of a garage and has since turned the automated manufacturing systems provider into an international enterprise.

On the first episode of The Roboticist Chronicles, host Tyler Kern sat down with Allford to explore the history of ARC Specialties and analyze how its trials and tribulations reflect growth and challenges within the industry.

Continuity and steady growth kept ARC on an upward trajectory over the decades, and Allford said that sometimes it is not about what a company does, but what it does not do.

“As long as you keep your mistakes commensurate with the size of your business, you’ll survive. So, while we were small, we made small mistakes, and we survived,” Allford said.

ARC has endured the globalization of manufacturing which has seen jobs leave the United States, but Allford said the industry is entering a renaissance in America today. Certainly, that is a welcome sight to Allford, who after almost forty years still has an unwavering passion for welding and manufacturing.

“I still like building things,” he said. “The only thing better than building something is building something that builds something.”

After creating jobs in more than 20 countries, Allford’s greatest build may not be a product but an exemplary company.

ARC Specialties | Robotic Drill & Tap System with Automatic Part Registration

ARC Specialties | Robotic Drill & Tap System with Automatic Part Registration

ARC Specialties features a robotic drill & tap system with automatic part registration. The process occurs in 5 stages. In stage 1, the part is randomly placed near the robot, a Fanuc Robot with ARC software integrated. A Renishaw touch probe is used for automatic part registration, and then probing begins. Stage 2 is the drilling stage. Here a custom drilling spindle is used to drill the hole pattern. During the inspection stage, the FARO coordinate measuring machine confirms hole pattern and placement accuracy. This machine features an advanced user interface that streamlines and simplifies registration and machining. Tapping is stage 4, and in this stage, a floating tap performs the tapping operation using the robot’s 6th axes. And finally, in stage 5, the Vermont Gage Go/NoGo Thread Gage inspects the tapped hole for accuracy.

This innovative approach allows robots to replace machine tool operations with increased flexibility and reduced cost. Integrated solutions by ARC specialties are the product of our unique experience and commitment to excellence.
