20Pcs Aluminum Welding Rods Solid Core No Flux Required Low Melting Point Corrosion Resistance

These aluminum welding rods are no solder powder needed, wide applications and perfect welding effect.

Features:
Suitable for welding or surfacing welding alloy with high strength, well forgeability and well corrosion resistance.
Made of high-quality aluminum material, non-toxic, odorless and durable.
There is no need to use other flux powder with aluminum alloy as the welding core and coating as the salt base.
Include welding filler wire and spray and flame metalizing wire. It also used for argon arc welding and filling material for pure aluminum, connection with aluminium bus and guide rod of electrolytic aluminium plant and electric power, chemistry, food and so on.
Designed with full and smooth welding effect because the item comes with internal powder, well weldability and corrosion resistance, high thermal conductivity, high electric conductivity and high processing performance.

Note:
These aluminum welding rods are solid core, can only be welded with aluminum.

Usage:
1. Clean and polish the physical surface.
2. Heat the surface of the metal material until the temperature of wire is up to the working temperature 380℃ to 400℃.
3. The aluminum base metal is heated to the appropriate working temperature when repairing thin aluminum, and then use the wire  friction and melt to form a weld.
4. Use propane gas to weld small object and use industrial gas or induction heating device to heat and weld big one, you should cool it naturally after welding.
