Low temperature aluminum welding wire core aluminum welding rod

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.
