Technical Requirements For Aluminum Transition Belt Material

Copper: T2, T3 copper plate

Aluminum: L3, 1070, 1060 aluminum plate Product manufacturing process

(1) Flash welding

(2) Friction welding

A: Flash welding instructions

(1) The weld is complete without porosity and cracks

(2) The misalignment of the horizontal plane does not exceed 2.0mm, and the thickness misalignment does not exceed 0.7mm

(3) The surface of the aluminum transition belt is smooth and clean, and the local scratch degree is not more than 0.5mm

(4) The welding seam should not be broken when the aluminum transition zone is bent 180°

B:Friction welding description: Friction welding is a solid welding method to achieve welding. It uses the heat generated by the mutual movement and friction of the workpiece ends to make the ends reach the thermoplastic state, and then quickly break off to complete the welding method. Step process:

(1) Converting mechanical energy to heat energy

(2) Plastic deformation of materials

(3) Thermoplastic down forging pressure
