Can a seam welding be done with too high current?Can a seam welding be done with too high current?The same case holds true for the seam welding. In case of a seam welding, you have to take a care about the current that you are supplying. If the supplied current is too high then, the interface between the welding plates and roller will be very hot, in such conditions seam welding cannot be done properly.What is Seam Welding and How it Works?

In a TIG weld, argon, or another gas such as helium, flows through the welding cup to flood the seam and push out the oxygen. This prevents oxidation on the top surface, but the underside is still exposed.

Feb 11, 2012Usually for telescopice tubing we buy 3/16 wall and get the tube that goes inside 1/2" smaller than the outside tube. This give an 1/8" of room for the weld and the tube is free to move.
