When the robot’s working envelope is too small for your project you need a RTU. At ARC we design and build RTUs to fit your needs.

Eight is (much) greater than six when it comes to robot axes. In this episode, we showcase how a two-axis part positioner with coordinated motion will allow your six-axis robot to do things no human can.
Regular viewers of Weld of The Week seem to enjoy both cutting-edge as well as older technology. This episode showcases an odd old technique. I would like to read your comments if you are familiar with it.
I have made a good living building machines that make welded coatings on a variety of parts around the world. Welding creates strong metallurgical bonds between the coating and the part. But there is another way: thermal spray.
No other arc welding process allows you to make full penetration welds on a variety of metals up to 3/8” thick without a bevel and without filler material. The arc punches through the part creating the “keyhole”, molten metal fills behind the arc making narrow deep weld through the entire section.
Plasma Transferred Arc Welding (PTAW) is a great process for robotic joining and overlay. The tightly columnated arc focuses the arc energy in a small area, making torch height less critical. The tungsten electrode is protected. So you change the tungsten less and weld more. PTAW allows the use of powdered filler materials, so you can weld all sorts of composite and exotic metals.
