some fun practice

admin

Well i had the welder out today and was bored so after seeing some of the work zapster has posted i thought i'd give it a try. I'm not sure what everybody around hear calls this bead i've heard "stitch" "double stitch" "weave" and a couple others. this two peices are my first attempt at a stitch weld on pipe i've done probably 5 or so welds on flat plate. but i thought i'd see what you guys thought and if you had any suggestions. and here are the settings and info if anybody was wondering. 1/2" steel plate2.1/2" o.d. tubing 1/8th " wallmiller syncrowave 200.1/16th inch 2% thor.tungsten with gas lens.130 amps.straight argon.er70s2 roughly 1/16th"
Reply:copycat!!well its a start..but i can tell that you just did a stitch pattern..wich is ok..but as a general rule of thumb you need a root pass done first then you stitch over it..thats how you keep the middle "raised" up a bit..ok no more secrets... ...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.

Reply:thanks for the help. but that's odd i did do a fusion root pass with no filler like you talk about. do i just need more heat to burn it in more?
Reply:root pass with filler works for me..stainless gets the fusion pass first..then a filler...then the stitch.. ...zap!I am not completely insane..Some parts are missing Professional Driver on a closed course....Do not attempt.Just because I'm a  dumbass don't mean that you can be too.So DON'T try any of this **** l do at home.
Reply:ok thanks it makes sense i'll have to give it another try.
Reply:You done a good job on weaving.Try to palse for 2 sec on each side you will see the puddle blend in to the pipe.You'll see there want be any undercut.I noticed you used 1/16 th tungsten.that's kinda small for that amount amps  I use 3/32 to weld stainless up to 120 amps. I change to 1/8 to weld carbon.The tip will burn off and contaminate the weld.I do x-ray welding on pipes and pressure vessels.Give it a try let me know how it turns out.Good luck
Reply:I see undercut on the top side of your welds.Stop on the sides for a 2 sec you will notice the puddle will fill the undercut in.
