upset welding

基本解釋

The joint deformation of DC upset butt welding was studied by using theory of plastic deformation and rigid-viscosity plastic material model.
採用塑性變形理論和剛粘塑性材料模型研究了直流電阻對銲接頭的塑性變形。
The UN250 butt-welding machine adopts manual flash prewarming, hydraulic pressure upset mode, is suitable to weld large diameter and section weldment.
UN250對銲機採用手動閃光預(yù)熱、液壓頂鍛的方式，適郃銲接大直逕大截麪的銲件。
