5 All-State
Sealcor® Flux
Cored Alloy for Aluminum Welding and Brazing Torch
Application General
Characteristics A
special aluminum rod with the flux contained in the core where it is protected
from moisture and rough handling. This
alloy is so unique that it can be used on all weldable grades of aluminum including
cast, sheet and wrought aluminums.
It is ideal for out-of-position work where absolute control is essential. All-State
Sealcor® aluminum rod
has a wide operating range; at high
temperatures, it flows freely but at low temperatures, its high viscosity enables
it to be used
for build up and filling gaps. Typical
Applications For
fabrication, repairing cracks and breaks, building up missing or worn parts and
joining of dissimilar gauges. Qualities

Procedures Clean
weld area. Align parts, leaving a gap of 1/16" (1.6mm) to 1/8" (3.2mm) if possible.
Parts thicker than 1/8" (3.2mm)
should be beveled 60° to 70° when butt joints or cracks are involved.
Use a large tip with a carburizing flame
to heat the work piece, keeping the flame 1" (25.4mm) to 3" (76.3mm) from the
surface. Occasionally touch Sealcor®
to the weld area under the torch flame until filler metal begins to flow. Deposit
small amounts of alloy at
a time, allowing it to flow out. It is not necessary to melt the base metal at
any time. Flux residue should be removed
with hot water and stiff brush. Caution:
If rod is partially used, crimp end to seal flux.
