upset butt welding

基本解釋

The UN250 butt-welding machine adopts manual flash prewarming, hydraulic pressure upset mode, is suitable to weld large diameter and section weldment.
UN250對焊機采用手動閃光預(yù)熱、液壓頂鍛的方式，適合焊接大直徑大截面的焊件。

The butt welders use aluminum casting hull which is the secondary conductor, and are fixed with upset limit switch. The welding process can be finished under the proper current gear and upset force.
且設(shè)有頂鍛限位開關(guān)，選擇合適的電流檔位和頂鍛力，就能完成焊接過程。
In the process of DC upset butt welding, the joint quality was strongly effected by the temperature distribution in the direction of the plate width.
板材直流電阻對焊過程中，對接端面沿板寬方向的溫度分布對焊接接頭的質(zhì)量有很大的影響。
