upset welding

基本解释

The joint deformation of DC upset butt welding was studied by using theory of plastic deformation and rigid-viscosity plastic material model.
采用塑性变形理论和刚粘塑性材料模型研究了直流电阻对焊接头的塑性变形。
The UN250 butt-welding machine adopts manual flash prewarming, hydraulic pressure upset mode, is suitable to weld large diameter and section weldment.
UN250对焊机采用手动闪光预热、液压顶锻的方式，适合焊接大直径大截面的焊件。
