UN Series Flash Butt Welding Machine

UN系列閃光對焊機

整機特性：

將對接的工件，自動夾緊，再通過氣液控制，先通電緩慢推動將工件焊接處表面的氧化和凸起不平處閃光去掉后讓焊接的工件端面熱塑化，焊接區域變得越來越熱，對焊的速度也隨著加速，閃光和飛濺使兩個接觸面完全焊接在一起，.最后再迅速加壓頂鍛使焊接兩端面熔接，切斷電流，焊接完成。這種焊接強度高，致密性好，無假焊，無夾渣，無氣孔.

主要應用領域：

1.各種餐具，刀具的焊接;

2.自行車，摩托車，汽車車圈，及其他金屬環的對焊;

3.各種金屬帶，鐵棒，建筑用鋼筋，圓管，方管對焊；

Main Features:

Clamp the welding parts by welding electrode firstly without touch, then driving the welding electrode slowly together with a preheat current to flash clean the oxidation and uneven surface to make welding area as hot plasticizing. The temperature of welding area turn to more and more heat and the welding current density increasing together, flash and splash make two touch surface has melted together. Finally perform a fast upsetting force on welding joint to finish welding and breaking current. This type welding joint has high strength without false welding and pores.

Main Applications:

1.All kinds of dinnerware,knives ;

2.Bicycle rim,motorbike rim,car rim,or similar strip rings;

3.Various steel strip,steel rod, construction rebar,round tube and square tube ;
