Thread: Better than TIG?

A new welding method called DRW. Even welds dissimilar metals together! http://www.sema.org/main/semaorghome.aspx?id=54649

sweet...I can't wait for that one to hit the market.

When it hits the market you won't be using it in your garage. It looks like a electronic welder simalier to a spot welder porbably set up for one application at a time but welds and the like. We used to play with stuff like that when I worked for Reynolds

Thats got to be cool to see

We have been doing this for more than 25 years now using our own Homopolar generators.

sounds like production welding equipment. From the description I would expect it to roll-weld also ( continuous spot weld using roller wheels ) Haven't seen any roll weld done, but set up right it must be sweet to watch. Seen lots of precision spot welding though. It's all a balance of time, pressure, and amperage.

when a roll welder is set up right you don't see much except very few sparks and the die oil smoking next to the weld zone we used roll welders before robots to weld the roofs in the drip rail area when i started in the factory on the 65 mustang.
