More practice, Lap joint

3/32 6013 DCEN about 85 amps on the Maxstar.  Material is 1/8 thick and I didn't clean the mill scale off.  The slag came off in one piece.  Comments appreciated._________________________
Reply:6013s give great beads.  One comment, looks concave like not weld is being put down.  I'd try dropping your Amps down a bit as they seem a bit high for 3/32's.  See if you can get it so there's just a small weld bump *above* the work material.  Could just be that photo, but it looks dug in to the material a bit.  Not bad though!6013's are good for sheet metal due to their penetration (they run on DC+ so most of the heat is built up on the electrode side, not the workpiece side.  You're running it DC+ (reverse polarity) right?"A winner isn't someone who doesn't lose, a winner is someone who doesn't quit."
Reply:I think that first pic has some optical illusions.  Here are a couple more pics from different angles._________________________

Reply:It shouldn't  have broke.  The plate should bend if its really part of the other one.  The weld looks good from the last pics.  I use 85-95 amps on 3/32 6013 DCEN.It looks like you didn't have enough weld.  The last picture looks like its cold, but it could be a lighting thing.DavidLast edited by David R; 06-29-2008 at 08:42 PM.Real world weldin.  When I grow up I want to be a tig weldor.
Reply:The slag peeling off in one piece usually means you are relatively close to the correct settings. I agree that the plate should have bent before the weld broke. It looks to me like you may have been moving a bit fast and that may have limited the weld penetration. All in all not to bad if you are just starting out.
