Spot Welding of Aluminum in Automotive Applications

1. Solutions:
1) High welding current
2) Short welding time
3) Adaptive adjustment

2. The AluSPATZ+ aluminum welding equipment is composed of the following components:
1) ServoSPATZ+ welding control cabinet, with a maximum welding current of 80 kA.
2) AluGATOR servo welding gun, which is equipped with two servo motor drive mechanisms:
3) To provide and control the welding pressure.
4) To provide the gravitational balance along the axis of the welding gun electrode.
5) Electrode caps processed by the CapClean 3D electrode dressing device.

3. Advantages of the AluSPATZ+ aluminum welding equipment:
1) The AluMASTER adaptive control system can compensate and adjust for the following process interference factors:
2) Shunt situations
3) Gap between plates
4) Differences in the surface quality of aluminum materials
5) Instability of adhesive application
6) Poor self-balancing of the welding gun
7) Poor perpendicularity between the welding gun electrode and the surface of the plate
8) Weld nugget index and welding gun index:
9) Monitor the welding quality and the diameter of the weld nugget in real time, and output the monitoring results immediately after the welding is completed.

4. Hybrid Welding:
The same set of equipment in the same station can achieve alternating hybrid welding of steel-steel and aluminum-aluminum.
