The truck bed is constructed by butt welding of steel plates and profiles, with crisscrossing stiffeners, resulting in a complex structure. The welding process is difficult to position, and the assembly and welding efficiency is low. Different truck bed models require secondary adjustments and positioning each time, and there is no universal auxiliary welding device.
