Prior to final heat treatment, the weld bead must be cold-worked by methods such as forging, planishing, drawing, swaging or bead rolling so as to obtain a flush condition on the inside and outside of the pipe. All specimens shall be subjected to transverse or longitudinal tension test, flattening test, and

Pipe Welding TutorialIf you are welding .5" pipe then you just need 2 tacks welds on opposite sides of each other. 4 tacks are used for pipe that is standard in size. A tack weld needs to have the same penetration and quality as the weld bead you will lay to finish the job. So don't tack over foreign material and thinks it's ok. It's not.

Welding Methods. Welded stainless steel tube is made from long strip or sheet, passed a rolling machine, then the strip edges is welded longitudinally and melt together, using various welding processes, making welding beam is as same as base metal, and form into tube shape.
Welding Forum > Welding of Stainless Steel without a purgeSep 17, 2007 · There are a couple of ways to weld stainless steel without purging the 'back' of the weld. I take it, your talking about TIG welded root runs? Solar-flux is one, Flux-cored wire is another. Solar-flux is a powder that is mixed with methanol to form a cream like paste, which is then 'painted' onto the inside of the pipe/plate.
