Description

A kind of laser filling wire welding technique

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.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, provide a kind of and can improve welding quality and the easy a kind of laser filling wire welding technique of simple process.

According to technical scheme provided by the invention, described a kind of laser filling wire welding technique comprises the following steps:

A, get wire feeding head, laser head, cross micro actuator, connecting plate, holder and chuck, for subsequent use;

B, cross micro actuator is fixed on laser head, holder is fixed on cross micro actuator, by one end of connecting plate by hinge on holder, by chuck by hinge on the other end of connecting plate, wire feeding head is arranged in chuck;

C, welding wire is loaded in wire feeding head;

D, regulate the silk feeding quantity of welding wire by wire feeding head, regulated the wire feed angle of the welding wire in wire feeding head by cross micro actuator;

E, start laser head carry out welding simultaneously by valve to laser head institute just right workpiece weld seam blow protect gas protect, the laser power control of laser head is built in 1300 ~ 1700W, the defocusing amount of laser head controls at 4 ~ 6mm, the wire feed rate of wire feeding head controls at 15 ~ 25cm/min, speed of welding controls at 1500 ~ 1700mm/min, shielding gas flow amount controls at 12 ~ 17L/min, valve distance laser head the distance of just right workpiece weld seam be 8 ~ 12mm;

F, make welding wire successfully send into molten bath, complete filler wire welding.

Described protection gas is helium, neon, argon gas, xenon or radon gas.

Invention increases welding quality, present invention process step is simple and easy to do.
