CUSTOMER VIDEO 15 - CORNER JOINTS ON STEEL AND ALUMINUM

This video is on 3 different corner joints.

• TIG welding a 11ga cold rolled steel outside corner joint
• TIG welding 3/16" thick 6061 aluminum corner
• MIG welding 1/4" thick carbon steel corner

For the 11ga cold rolled steel corner joint, I used a clear jazzy 10 cup and it worked great helping me film the arc and also to see the puddle clearly.

I used 105 amps and 20-25 CFH of argon along with a 3/32" 2% lanthanated tungsten and ER70S6 1/16" filler rod.

I welded the 3/16" 6061 aluminum corner with the Primeweld TIG325 at around 200 amps.

I used  1/8" 2% lanthanated tungsten and 1/8" 4943 filler rod. (4943 is a relatively new filler but has been around over 10 years) 

I have a water cooled setup on my primeweld 325 with a CK #20 water cooled 25 foot torch and I used a #7 clear cup and around 25 cfh argon.

Clear cups help me film better and also help me see the puddle and joint better.

The last joint was a 1/4" carbon steel outside corner and I used a primeweld MIG180 set at 18 volts and 196 ipm using .035" ER70S6 wire.
