TIG Welding 4 Corner Welds on Cold Rolled Steel

Comparing Pulse Settings vs no pulse on outside corner joints on cold rolled steel 11ga  0.120” (3mm)

For this video, I compared 2 welding techniques on outside corner joints on 11ga cold rolled steel.

Joint #1 was welded at 105 amps (machine set to 105 and full pedal) using 1/16” ER70S-6 filler straight DC current with no pulse.

Joint #2 was welded at 2 pulses per second with background current set at 30% using a 3/32” filler rod and leaving the rod in the puddle aka the “lay wire” technique.  

Certain weld joints work really well with  pulse settings and outside corner joints are definitely among them.

If your tig welding machine has pulse capability, 2 pulses a second with a background current of 30% would be a great place to start with the laywire technique …For the dab technique, 1 pulse per second or even 0.7 pulses per second would be a great starting point.
