Macro morphology of RFSSW
1. Technical Features
● No key-hole
By retracting and refilling welding tools, there is no key-hole after welding, and the joint has high performance.
● High rotating speed
The maximum rotational speed is 5000rpm, which can achieve a maximum downward insert speed of 5mm/s.
● High flexibility
By using a six-axis heavy load robot, three-dimensional spot welding can be realized.
● Automatic changing the welding tools
Adopting hydraulic structure, it can automatically change welding tools.
