5356 Aluminum Welding Rod Properties

The temperature definition of low temperature aluminum welding wire is mainly based on three temperature ranges

1. Low temperature aluminum welding wire at 580-620 degrees Celsius. Representative welding wire ER4047, ER4043

2. Low temperature aluminum welding wire at 380-450 degrees Celsius. Represents welding wire Q303, WE-Q303B, WE53, etc.

3. Low temperature aluminum welding wire at 179 degrees Celsius. Representative welding wire M51, M51-F

Welding principle：

Relying on the heat conduction of the base metal, and a little auxiliary flame to melt the welding wire to form.

Welding method：

1. Cleaning: Mechanical cleaning is the best way to clean the welded parts, the purpose is to remove the surface oxide film.

2. Heating: Focus on heating with thick parts. When heating, it can be a little farther away from the welding point, instead of directly burning the welding port.

3. Blanking: When the temperature reaches 400 degrees, lower the welding wire. The angle should be as vertical as possible to the spot welding point, and the tip of the welding wire should be melted and formed by burning the tip of the welding wire with the end of the flame at the moment of the spot, rather than deliberately burning the welding wire.

Industry scope：

1. The socket connection of aluminum pipes in the refrigeration industry, the dissimilar welding of copper and galvanized pipes for central air conditioning, stainless steel pipes, and aluminum pipes.

2. Welding of aluminum terminals, aluminum leads and aluminum conductive bars in the substation industry.

3. Welding of radiator tubes, motors and busbars in the electronic and electrical industry.

4. It is also used for faucets, coupling connectors, matching nuts, etc. in production and life.
