A chromium-free welding consumable and a method of welding stainless steel
to reduce the presence of chromium emissions. The consumable is made from
an alloy that reduces the emission of chromium during a welding process,
and include predominantly nickel, with between approximately five and ten
weight percent copper, up to approximately two percent by weight of
ruthenium and up to five percent non-copper alloying ingredients. Welding
consumables made from the alloy are particularly well-suited for welding
austenitic stainless steels, such as type 304 stainless steel. The method
involves using chromium-free weld filler material with a stainless steel
base material.
