Electrons are Cheaper than Photons (by the watt)

My first job was in the Hughes welding research lab and I loved it. But my lab experience started as a youngster going to my mom’s radiation mutation genetics lab at UT Austin. My job was pipetting mutated drosophila (moving fruit flies from one test tube to another by sucking them up in a straw). Laboratories are in my blood.

We built our lab at ARC Specialties years ago so we could determine project feasibility and optimize process parameters BEFORE we build a machine.

In our lab, we have answered questions such as can you weld MoRe? Pure Tungsten? Make bullet-resistant coatings on Ti? Clad pipe 40′ deep? Use ESW for additive? Create wear-resistant coatings for aluminum? Maintain bond line flatness +/- .005′”? Too much fun!

This week’s challenge was to make .02″ thick metal to metal wear-resistant coatings for mud motor transmissions with a metallurgical bond, minimal cracking, and useable in the as-welded condition without a laser. With a little help from our friend Jean-Marc Tetevuide we succeeded.

If you have a manufacturing problem you would like for the ARC team to investigate contact me. If it is interesting we won’t even charge you!

At ARC Specialties we thrive on problems, send us yours!

Plasma University

Plasma welding is a wonderful process for welding automation. Plasma torches protect the tungsten, collimate or focus the arc plus allow to use powdered filler materials rather than just wires. These features make plasma the welding process of choice for overlay and joining in many applications. But it is not widely understood and not taught in depth in schools. I was fortunate to have several excellent mentors Chip ArataRod Webber, and Dave Hebble who taught me the nuances of the process.

When we build and install plasma welding systems we are asked to teach the process to operators and engineers. I developed this 1-hour class and have presented it to my customers in the US and around the world. We decided to video Plasma University and post it. Watch the class, successfully complete the quiz, and we will send a certificate!

Our plan is to add other processes and other classes, tell us what you are interested in seeing in the future.
