What welding processes are adopted for Jianxing semi-trailers? What are the technical advantages over traditional processes?

Dual processes of automatic submerged arc welding and CO₂ gas shielded welding are adopted, equipped with robotic welding stations. Compared with traditional manual welding, it features higher weld uniformity, lower welding defect rate, smaller heat-affected zone, and controllable frame deformation, which can significantly improve structural strength and the fatigue life of the whole vehicle.
