  • MIG Welding Stainless Steel, TIG Welding

    If while welding the carbon steel pipe root, the welder uses higher current, slower weld speeds or a wider weld weave, the 309L weld can end up with more weld dilution with the carbon steels, reducing the weld ferrite level and making the weld more austenitic.

  • WELDING OF STAINLESS STEELS AND OTHER JOINING …

    stainless steels have several characteristics that require some revision of welding procedures that are considered standard for mild steel. As illustrated in Table 2, the melting point of the austenitic grades is lower, so less heat is required to produce fusion. Their electrical resistance is higher than that of mild
