Welcome to ARC Specialties
The design of one of a kind machinery requires the experience and knowledge that ARC
Specialties and its staff can furnish. From the original specification to the delivery
and setup of a custom system, ARC Specialties' staff will work to achieve an excellent
product that will meet or exceed the customer's needs. Our experience includes metal
welding and cutting applications, material handling, pick and place machinery and test
equipment. ARC Specialties can design machinery that will change your manufacturing headaches
and bottlenecks into a high quality, high production and high profit part of your operation.
What We Do
- Cutting (plasma and flame)
- Material handling
- Machine vision
- Pressure and vacuum testing
Latest Technologies: Profile Mapping Tool (PMT)
ARC Specialties’ latest technology the Profile Mapping Tool (PMT) was first unveiled in April 2010 at ARC’s Vision
Systems seminar. PMT is a fully automated camera system and software package that scans the profile of clad pipe with a
resolution of .001” and can detect defects that often go undetected in liquid penetrant tests.

Precision cutting on heavy-wall vessels is not normally considered a robotic application,
but the unique requirements of one project required some new thinking.
Enpro Systems, a Houston vessel manufacturer, recently fabricated a 49-foot-6-inch-diameter
hemi-spherical vessel with 2 7/8-inch steel walls. The vessel had 28 connections of 16.5-inch pipe
through the wall. Cutting round holes isn't usually a major problem, except these holes were
parallel and located between the "pole and the equator." So to cut a round hole required
a complex torch path to follow the angle of the wall and the curvature.
Standard circle-burning machines could not handle the 20 inches of rise and fall of the
torch path cutting on the vessel's curvature. The hole angle meant that the cut was actually more
than 5 inches thick. The thickness and accuracy requirements ruled out manual cutting, and the
customer's tight deadline precluded fabrication of a custom cutting system.
Enpro ultimately chose a different approach--robotics--partnering with Arc Specialties, a
Houston-based company specializing in automated manufacturing systems. Arc Specialties
proposed to use an ABB IR1400 welding robot as a programmable burning system.
