61-T For Magnesium
Repairs (TIG or Brazing) General
Characteristics All-State
61-T is a general alloy for torch brazing and TIG welding of magnesium sheets,
plates, extrusions, and
castings. Typical
Applications For
fabricating and repairing magnesium parts such as dock plates, building up worn
or missing sections, and correcting
defects in magnesium castings. For use on such base metals as AZ92A, AZ61A, AZ80A,
AZ91C, AZ81A,
and AZ31B. Qualities

Procedures I.
TIG — Use AC with superimposed high frequency
as in aluminum procedures with Argon or Argon-Helium
gases.
Base metal must be free of protective acid or chrome pickle coating as well as
any oil
coating which must be removed just
prior to welding or brazing. Mechanical cleaning with stainless steel
wire brushes is preferred for most
applications. Vapor degreasing or a degreaser that leaves no residue
will
remove oil coating.
