Bare Solid vs. Metal Cored 316L Filler for GTAW Welding
Bare Solid vs. Metal Cored 316L Filler for GTAW Welding
(OP)
Is the use of metal cored filler permitted for pressure vessel construction? What does a metal cored filler get you as an advantage over a solid filler?
What exactly does flux do the welding process. Does it contaminate the weld and make it weaker?

For flux core arc welding (FCAW) you have options using a metal core wire with flux. Gas shielding can be provided as a supplement. There is plenty of information on the internet regarding GTAW, FCAW, wires and flux.

One thing to note is that it practically only works for a single pass, then your subsequent passes should be with normal process (ie GTAW w/ solid or GMAW, SAW, FCAW). It also only works well for open root welds that have proper fit-up. I don't think it ties in well when you have backing. Also, clean up between passes , if I remember, may be less than perfect.
