Our semi-trailers adopt automatic submerged arc welding, CO₂ gas shielded welding and robotic welding processes, featuring uniform weld seams, high structural strength and low defect rate. Combined with overall shot blasting after welding to eliminate welding internal stress, the structural strength and fatigue life of the whole semi trailer are reliably guaranteed.
What welding process do your semi-trailers adopt? Is the structural strength guaranteed?
