I'm mostly a pipe stick and tig welder thou i'm gonna get a mig welder to weld some exhaust pipe. what wire you use for that and any comment's w/ it as well, thx mjz

[mark4561]

stress test

I have alway's been nearvous on test day's even thou I did it a 100 times already before. Take an extra breath and slow down, i was alway's tryin to hard and made stupid mistakes i normally would never do, slow ypor speed down and make sure you give the weld time to flow keep...

whip motion

don't forget the whip motion w/ that, 1/8 burn's good at 100 110 ,cram it in and hold then pull back quick , keep your tip of wire pointing up a bit ,help's suspend the steel a bit to.

stringer

done alot of the verticle basket weave, is the stringer style all that much different? besides tryin to keep it straight in line w/ each other,

running stringer's

that's what I meant too ask, forgot that stringer part. But yah tip's for stringer's verticle 3G typical structural test, gonna do one tomorrow and normally do that w/ full basket weave style, thx mjz

[mark4561]

normally do the verticle up 7018, fill as I go. but alot of companies want verticle bead weld,can't be to much different than standerd verticle fill, any comment's or suggestion's, thx mjz

Bought a joker auto len's about a 1 1/2 yrs ago, doesn't seem to work right all the time, seem's like at times I'm welding w/ my eyes closed, the adjustment's don't seem to help either, anyone know of or experienced any problem's like this w/ these helmet's, thx mjz .

tungsten

if it's worth it I'll try to keep one end for aluminum and the other for carbon pipe,I use a soap stone and a little arch flash for undernieth the pipe. Would like a see through or florecsent stone if you know where to find one,also anyone ever try those pen's they sell on ebay...

[mark4561]

anyone in the pipe welding side know of some good literature, am testing for pipe 6011 and 7018. Tig welding to start, then pipe gtaw w/ 7018 cover. most all job's I've come across want tig root w/ 7018 cap.Am continuing education from structural welding and get on the ground for awhile,lol. feedback...

[mark4561]

not much experience w/ fluxcore, till now. Question's about root pass for bevelled plate, vertical, overhead. Do you start a bead up then stitch it in like a 7018 or down bead and fill root pass in w/ beading, thx

[mark4561]

anyone ever asked to do a vertical bead w/ a 6011 root pass, all from down to up!, not a weave as I thought it was alway's to be, goes against my trained logic, maybe need some insight. thx

mig

have my 3 G cert, the job posted was inner shield welding and I know the structure is galvinized. I wasn't sure that's what they wanted, A mig welder for that. It usually call's for standard 7018 stick for structure. They have to heaty it also outside when it's cold like this time...

[mark4561]

Is that similar to mig welding?...

[mark4561]

someone please explain the inner shield to me , I think it's simple afraid to ask dumb question's but appreciatew it. I wasn't sure if it's a certain techniqe or not ! thx so much everyone.
