Reinforcing steel BRANZ BuildJun 01, 2010 · This is a more efficient process, producing a steel (usually labelled QT or QTR) that must never be rebent hot or cold and cannot be welded because it de-tempers the steel. Cutting a thread on the end of this steel should be avoided as it cuts into the higher yield steel, having a bigger effect than cutting a thread on the micro-alloyed steel. The Pros, Cons and Best Ways of Welding Stainless SteelOct 09, 2019 · The not-so-simple answer is, it depends on what result youre trying to achieve. Stainless steel can be welded with shielded metal arc welding (MIG), gas tungsten arc welding (TIG) and stick welding, and each of these processes will yield a slightly different result.
