What is Resistance Welding : RWMA : American Welding Society

A great feature of MIG welding is that it can melt different sized metals together, though it is mainly used for thicker pieces. Setting the gas on a MIG welding set can be simple, requiring limited background knowledge on welding. Today, MIG welding will be explained, and you will also learn how to set shielded gas used for welding.

Mechanix Wear Launches Torch™ Welding Series Gloves for ...

Jan 04, 2020 · Resistance Seam Welding: In principle seam welding is similar to spot welding except that it uses disc shaped electrodes. A current impulse is applied through the rollers to the material in contact with them. The heat generated thus rollers to the material in the pressure from the electrodes completes the weld.

Resistance Welders | Spot, Projection & Seam Welding [ 844 ...

A seam welder is a device that utilizes a variation of the spot welding technique to weld continuous seams. Seam welders typically consist of two rotating wheels each forming a separate electrode with a gap between them. The workpiece sheets are pulled through this gap while an electric current is pulsed between the wheels.
