Aluminium Welding Rods For Stick Welder

The melting point of pure aluminum is 660.37 degrees Celsius, while the melting point of aluminum alloy is 482-660 degrees Celsius depending on the alloying elements it contains. When aluminum and aluminum alloys are heated from room temperature to a molten state, there is no color change. It is very difficult to judge the temperature of the base metal during welding, and it is easy to overburn or melt the base metal. The temperature of low-temperature aluminum welding wire is mainly defined in three temperature ranges.

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
