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.
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.
