Hey guys so been having to weld stainless out of position lately. Mostly shielding work on boiler tubes in vertical position...we've been using 309-15 3/32 rod and its been alright but I've had some trouble. Haven't done much stainless before and definitely not on material this thin. Any advice or techniques? Mostly I've been running it like 6010 but still gets a little soupy on me sometimes and drips....could this just be my heat or possibly technique I'm using?.....I've noticed some of the more experienced guys using a kind of quick tack technique. Instead of a full whip like 6010 they will break the arc in between ripples on the bead....worth a try?...any help is appreciated for a learning apprentice like myself
Reply:We did a large structural stainless job a few years ago and the rods were part of the wps- I think they were kiswell brand 308. We found a long arc worked well with a slightly exaggerated weave to move the slag. Latley we did a water filtration system and used some lincoln and some murex rods- they both ran different, but much better than the kiswells.
Reply:Thanks but I don't have much of a choice in rods because they are supplied by the contractor...also I was wrong that the rods are actually 310-16. I been welding with them all day and pretty much got things at a basic but more practise is most definitely needed...it's not simple welding stainless with how awkward of positioning we are put...I find myself using lots of different methods/switching hands etc. I found that downhand method worked the best after I got my heat right...any other tips appreciated tho thanks guys!
Reply:Maybe i'm missing something…and not to be a dick…but why don't you ask the dudes you work with who are doing the same thing your are…the "more experienced guys"
Reply:When you are running stainless arc welding electrodes, give the electrode a shake - not side to side, but up and down. with 6010, I would imagine that you'd either be doing concentric circles, or a whipping motion from side to side - with stainless, give the welding electrodes a little bit of arc length, and just the tiniest of up and down movements - but these movements are extremely quick up & down movements, and the movements are only literally like a 16'th, that you are actually moving or "shaking" the electrode, as you progress with the weld. If for example you are capping a horizontal weld, in the direction of travel, whether from left to right or right to left, in the direction of travel, you will be very quickly giving the electrode a "shake" up and down that is really only a 16th or less of a movement, but a shake of the electrode none the less. I don't know why that specific movement works, but it will help you every time.46 sae30047 sa200 w/Wisconsin VF451 shorthood56 shorthood56 shorthood68 redface69 redface07 ranger 305G13 sae300Inconel/Hastelloy SS Duplex Chrome/Carbon Tig F3Downhand STT/RMD F3F4 B Pressure |
