ALL-STATE®
34 Typical Application:
Repairing holes or cracks in aluminum
housings. Procedures
Clean weld area thoroughly. Any base
metal heavier than 1/8" (3.2mm) should be beveled at a 75 degree angle.
No preheating is necessary on thin
material but on heavy sections preheating to 400°F (204°C) is recommended
to flatten the
weld bead and reduce the amount of amperage required. Stringer beads are generally
used since some
undercutting will be encountered with weave beads. A short arc should be maintained
with the electrode tilted
slightly in the direction of travel. Allow to cool slowly. Remove slag before
quenching. Additional cleaning and
slag removal may be done with a wire brush and a solution of 5 percent nitric
or 10 percent sulfuric acid in
hot water. Rinse with clean, hot water. Diameters
and Recommended Amperages 3/32"
(2.4mm)—50-80 1/8"
(3.2mm)—80-130 5/32"
(4.0mm)—100-160 Identification
