UN Series Flash Butt Welding Machine

UN系列闪光对焊机

整机特性：

将对接的工件，自动夹紧，再通过气液控制，先通电缓慢推动将工件焊接处表面的氧化和凸起不平处闪光去掉后让焊接的工件端面热塑化，焊接区域变得越来越热，对焊的速度也随着加速，闪光和飞溅使两个接触面焊接在一起，.最后再迅速加压顶锻使焊接两端面熔接，切断电流，焊接完成。这种焊接强度高，致密性好，无假焊，无夹渣，无气孔.

主要应用领域：

1.各种餐具，刀具的焊接;

2.自行车，摩托车，汽车车圈，及其他金属环的对焊;

3.各种金属带，铁棒，建筑用钢筋，圆管，方管对焊；

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 ;
