II. Brazing
Weld or braze as soon as above cleaning procedure is finished since magnesium
alloys form a very tough
magnesium oxide coating when exposed to the atmosphere. For brazing, joint clearances
should be .004"
(.1 mm) to .010" (.3 mm). Lap or fillet type joints are recommended. Bevel sections
thicker than
1/8" (3.2 mm) 75 to 90 degrees. Using a slightly carburizing flame, preheat to
approximately
400° F (204° C). Sprinkle All-State®
61 Flux on joint area or dip heated end of rod in flux
and continue to heat joint until flux liquifies. Add drop of alloy and flow it
out continuing this procedure
until job is finished. Allow to cool slowly and remove all flux residue with hot
water and brush.
