Description
Technical field
The present invention relates to a kind of laser welding process, especially a kind of laser filling wire welding technique.
Background technology
Single laser welding technology is welding procedure comparatively novel at present, and compared with traditional arc-welding, its major advantage is:
1, speed of welding is fast;
2, welding finished product distortion is little is not even out of shape;
3, welding efficiency is far away higher than traditional arc-welding;
4, welding heat affected region is little, and weld strength is better than traditional welding;
5, for the product needing processing welding lines, the post-processed time is faster.
There is certain drawback in single laser weld process technology simultaneously, specific as follows:
1, single laser spot diameter is little, high to equipment requirement;
2, single laser weld is in welding process, and mother metal gasification forms plasma evaporation, and face of weld is not full;
3, early stage, weld seam requirement on machining accuracy was quite high, and except processing cost increases, too high machining accuracy cannot ensure;
4, single laser shows very poor in welding serious forgiveness, and the problems such as teaching error, mother metal machining accuracy and equipment precision easily cause appearance of weld bad.
