Low temperature aluminum welding wire core aluminum welding rod
Price Updated on July 20, 2022
Important Information:
Flux cored aluminum electrode.
Specification: 1.6/2.0/2.4mm thick, each 50 cm long.
Low-temperature aluminum flux-cored welding wire can weld almost all
white metals, including aluminum, aluminum alloy, aluminum-magnesium
alloy and dissimilar welding between the above metals, even for white
metals that have been severely corroded or polluted by oil, and even
aluminum that is considered irreparable All alloys can be repaired. Suitable
for all-round welding by primary welding operators, only a small heating
device is needed, the weld strength after welding is generally higher than the
strength of the base metal itself, and it is enough to know the gas welding
operation.
Instructions for use of low temperature aluminum welding wire.
Step1: through physical cleaning, polish the surface.
Step 2: Heat the surface of the base metal at the welding place until the
temperature reaches the working temperature of the welding wire
380℃-400℃, so that the welding wire can be melted by the heat conduction
of the base metal to form a weld. Do not use flame to burn the welding wire,
and only when the mother When the surface temperature of the material is
sufficient, the welding wire can flow and penetrate into the metal capillary
well.
Three steps:
When repairing thinner aluminum, just heat the aluminum base material to a
suitable working temperature, and then use the welding wire to friction and
fuse to form a weld. Only use a metal brush to melt the welding wire to fill
the weld to form a weld.
Four steps:
Small parts are welded with propane gas, and large parts are heated and
welded with industrial gas or induction heating device. After welding, they
will naturally slow down.
Precautions:
The thicker the piece, the more troublesome it will be to heat up, so it is
very important to use a reasonable heat source, as long as the surface
temperature of the base material reaches the level of the welding wire.
Working temperature, welding can be carried out. When using oxyacetylene
welding, use neutral flame welding, but do not directly use fire welding wire
Applicable heat source: It can be used for many kinds of heat sources, such
as propane, oxyacetylene, etc.
Storage: Store in a ventilated and dry place for long-term storage
Pay attention to details.
1. The surface of the base material must be cleaned. Clean and weld.
2. The temperature of the base material must reach 400°C, including the
temperature of the base material during the welding process, and the
temperature can be high or low.
3. Taboo use flame to burn the welding wire deliberately. After the base
metal temperature reaches 400℃, the welding wire will naturally melt by the
heat conduction of the base metal.
