ERAZ92A magnesium welding alloy is a good
choice when welding magnesium base metals
of similar chemical composition. It produces
superior joints with the maximum tensile
strengths offered by these alloys. Cleanliness
of both the filler metal and base metal is extremely
important when welding with magnesium.
Flux is NOT required for TIG or MIG
welding processes of ERAZ92A magnesium
alloy. Although Oxy-acetylene welding of this
alloy is uncommon it can be done and should
be limited to single-pass welding on thin
gauge magnesium materials.
