To achieve the above object, the present invention is realized according to following technical scheme：
A kind of compound molten bath concussion welding methods of laser scanning-TIG, cross laser scanning and the compound realization of TIG weld all,
It is characterised in that it includes：
During welding, laser scanning groove is selected preceding, after TIG welding guns are welded on, or before TIG welding guns are welded on, laser
The posterior two kinds of composite welding modes of groove are scanned, and the track in laser scanning molten bath is according to different materials and welding requirements
There is different modes, the scope of laser scanning groove both sides is identical or different, or laser only scans the side of groove.
In above-mentioned technical proposal, the angular range between the laser and the TIG welding guns is in 15-60 degree.
In above-mentioned technical proposal, the laser center point and the distance range at the molten bath center of the arc electrodes of TIG welding guns
For 1-6mm.

In above-mentioned technical proposal, the track of the laser scanning welding pool for circular, oval, sinusoidal, triangle or
For the scanning track in optionally specific region.
In above-mentioned technical proposal, the track of the laser scanning welding pool is that linear reciprocation or transverse reciprocating are swung
Scan track.
The present invention compared with prior art, has the advantages that：
Compare and Laser-TIG Hybrid Welding, except the humidification that intercouples of electric arc and laser, add fusion penetration, together
When by high-velocity scanning molten bath, realize the stirring action in molten bath, improve solidification and crystallization process, refined crystal grain, improved
Tissue, it is suppressed that the defects of stomata.
It is more flexible compared to the whipped form such as electromagnetic agitation, ultrasonic agitation, frequency, the width of scanning can be easily varied
Value, the track of scanning, the region etc. of scanning, for improving solidification and crystallization process, suppressing weld defect etc. advantageously.
Laser is untouchable thermal source, and molten bath can be scanned at a distance, therefore is needed compared to electromagnetic agitation etc.
Attachment device, its accessibility are more preferable.
, can also be significantly due to having mutual coupling humidification between laser and electric arc while agitation molten pool
Increase fusion penetration, improve welding efficiency.
