1、Process Introduction | What can robot welding solve?
High consistency: repeatability accuracy ± 0.05 mm, stable weld appearance and penetration depth, eliminating manual fluctuations
High speed: MIG speed can reach 1.2 m/min, which is 2-3 times faster than manual operation
Complex path: Six axis linkage+external axis, completing spatial curves, intersecting lines of circular pipes, and welding on the inside of narrow cavities
Controllable thermal input: pulse/dual pulse/cold metal transition (CMT) mode, reducing sheet deformation ≤ 1 mm
Multi process switching: MIG/MAG/TIG/plasma arc/laser composite, one machine for multiple purposes
