Selection and using providing more spaces on material.(3) comprehensive performance and some other performances of material can be improved, such as
Corrosion resistance, wearability etc..(4) it is used as transit joint.It is frequently necessary to welding dissimilar metal in industrial application, uses routine
When fusion welding, intermetallic compound just will form between dissimilar metal, but if using transit joint, between different metal materials
Welding become the welding of same metal material, both ends are same materials, even with conventional fusion welding, will not be gone out
The existing above problem.Application No. is 201610695861.5 Chinese patent propose a kind of laser-impact welding metal-loaded silk and
The solid State Welding of wire and plate may be implemented in the welder and its method of plate, the invention, and hot shadow is not present after welding
Area is rung, the not generation of intermetallic compound, welding quality is high, the mechanical property of welding point can be improved, this method is
It is welded at normal temperature, those is then difficult to weld to the metal that temperature requires with silk in the welding process, and
Only single energy field.Enhancing foil under a kind of Laser shock loading is proposed application No. is 201610688698.0 Chinese patent to connect
Connect the device and method of intensity, the invention under thermal condition, by base foil preheat, improve its plasticity, be conducive to base foil with
Impact welding between multiple foil, material flows in a mold for multiple foil and base foil after being also beneficial to welding, and then is conducive to foil
Between clamping in addition, the drive mold device in the invention can drive activity upper mold to move left and right, and self-locking can be played, improved
Working efficiency, carries out although this is welded under thermal condition, and it is self-locking that this method needs additional cylinder to control workpiece, dress
Set it is cumbersome, it is troublesome in poeration.

The air pressure difference of upper plenum (42), lower cavity (43) is played, piston (19) is pushed to move upwards, realizes briquetting (15) to be welded
The automatic impaction of plate (23)；
S4: making halogen lamp (14) in suitable position by adjusting bellows (31), then setting the temperature of halogen lamp is 50-
It 350 DEG C, is heated to shock plate (13), keeps the temperature 2-3min；
S5: shock plate (13) and fishplate bar to be welded are adjusted by computer (1) control constraints layer backing positions regulating device (10)
The distance between (23)；The position that three coordinate mobile platforms (26) are adjusted by three coordinate mobile controllers (35), so that pulse
The laser beam (4) of laser (3) output focuses on absorbed layer (41) by reflecting mirror (5) and condenser lens (6)；Pass through focusing
Lens carrier apparatus for adjusting position (8) adjusts condenser lens (6) at a distance from absorbed layer (12), to adjust hot spot；
S6: the laser beam (4) that computer (1) accurately controls acts on absorbed layer (12), generates explosion plasma, and plasma drives
Dynamic shock plate (13) high-speed cruising, hits fishplate bar to be welded (23), realizes welding；
S7: warm controller (36) is controlled by computer (1), warmer (40) heating is made to stop 3min, hot air temperature
Be gradually reduced, volume contraction, lower cavity (43) air by lower air inlet (38) enter cavity (29) in, upper plenum (42),
Air pressure difference is formed between lower cavity (43), so that piston (19) moves down, briquetting (15) unclamps automatically, can be taken off welding
Complete workpiece；
S8: repeating S3, S4, S5, S6, S7, it can be achieved that shock plate (13) and the batch of fishplate bar to be welded (23) weld.
8. it is according to claim 7 based on a kind of method for warming auxiliary impact pressure welding automatic clamping device, it is special
Sign is: the shock plate (13) and fishplate bar to be welded (23) are of the same race or different metal materials.
9. it is according to claim 7 based on a kind of method for warming auxiliary impact pressure welding automatic clamping device, it is special
Sign is: pulse laser (3) is short-pulse laser, and pulsewidth is 8ns~10ns；Laser energy is 5J-20J, laser facula
Diameter is 3mm-6mm.
