A practical engineering guide to purge methods, volume-exchange calculations, and oxygen targets for austenitic, duplex, and nickel-alloy pipe welds.

This article compares the two processes across eight technical dimensions—mechanism, weld quality, speed, cost, wall thickness suitability, nickel all

Fully austenitic stainless steel welds crack during solidification because, without a small amount of delta ferrite present, low-melting sulfur and ph

An essential variable is any welding parameter that, if changed beyond the limit set by ASME Section IX, can alter the mechanical or corrosion propert
