When welding stainless steels we want to make sure we do not exceed a 2-3% content of carbon dioxide and/or oxygen. A lot of shops will use the gas they use for carbon steel (such as 90% argon/10% carbon dioxide when mig welding) on stainless. What hides this problem is that it welds fine, and it looks fine.

Line Pipe Steels 90 to 100° C preheat eliminates cracking at moderate levels of applied stress when Grade 483 line pipe is misaligned during welding BY T. H. NORTH, A. B. ROTHWELL, A. G. GLOVER AND R. J. PICK ABSTRACT. Full-scale weldability tests showed that Grade 483 line pipe material was resistant to cracking up to very high Weldability of Steel The Metal Press by onlinemetalsLow-hydrogen processes to low-hydrogen fillers are necessary when welding these steels. Carbon-Manganese Steels. Carbon-Manganese steels have 0.15-0.5% carbon and 1.0-1.7% manganese. Generally these steels are weldable, although some steels will require controls on preheat and heat input. When welding carbon-manganese steels with higher amounts of

In general, gas tungsten arc welding (GTAW) is the best process to use on tool steel based on its amperage and control over feeding and aim. Gas metal arc welding is a better choice for fast filling and joining large pieces. If welding is the only choice, then you need to analyze the insert to find the best way to hold it during welding.

martensitic stainless steels. Steels with over 0.20% C often require a post weld heat treatment to soften and toughen the weld. 3.3 AUSTENITIC STAINLESS STEEL The austenitic stainless steels contain 16-26% Cr, 8-24% Ni + Mn, up to 0.40% C and small amounts of a few other elements such as Mo, Ti, Nb (Cb) and Ta. The balance between the Cr and Ni + Mn is normally
