UN Series Flash Butt Welding Machine
UN系列闪光对焊机
闪光对焊的主要焊接工艺及原理：
1.焊接电极加紧工件，在工件尚未完全接触时，开始闪光。
2.接下来，焊接电极夹紧的工件缓慢接近，随着电流密度的增加，工件间接触处开始熔化，同时有部分金属熔液溢出，形成初始的对焊节点。
3.焊接区域变得越来越热，对焊的速度也随着加速。
4.闪光和飞溅使两个接触面完全焊接在一起。
5.后再利用高压进行顶锻，切断电流，焊接完成。
The Main Principle of Flash Butt Welding:
1.The flash butt process starts when the two workpieces to be welded which are clamped by welding jams still not meet each other.
2.During the subsequence,move the welding jaws together slowly,the welding current density will increase,then the metal material in the gap between the jaws becomes molten,at the same time a shower of sparks also being emitted.
3.As the cross-sectional area in the welding becomes extremely hot,the motion is accelerated.
4.The flashing also makes the surfaces to welded together totally.
5.Finally the upset occurs at high pressure,the welding current is cut off.
主要应用领域：
1.各种餐具，厨房和餐具刀具的焊接;
2.自行车，摩托车，汽车车圈，及其他金属环的对焊;
3.各种金属丝，金属带，铁棒，建筑用钢筋对焊；
4.各种圆管，方管的“L”形与“T”形焊接；
5.窗框与门框的对角焊接。
Typical Applications:
1.All kinds of dinnerware,cooking knives and table knives;
2.Bicycle rim,motorbike rim,car rim,or similar strip rings;
3.Various metal wire and steel strip,construction steel bar and rebar;
4.Round,Square and Rectangular tubes welding into “L” or “T” shape;
5.Mitre welding of door and window frames.
