Laser welding is a high-energy beam welding, laser welding is the use of high-power coherent monochromatic photon stream focused laser beam for the heat source of welding; Tig welding is a kind of arc welding, the use of continuous feeding of the wire and the workpiece between the burning arc as a source of heat, by the torch nozzle gas shielding the arc to the welding.
The difference between the laser welding machine and the argon arc welding machine is: argon arc welding using non-consumable electrodes and shielding gas, commonly used to weld thin workpieces, but the welding speed is slower, and the heat input is much larger than the laser welding, easy to produce deformation. Laser welding weld is characterized by a small heat-affected zone range, the weld is narrower, the weld cooling speed, the weld metal properties of small changes in the weld, the weld is harder.
Two, handheld laser welding machine and argon arc welding machine which is good
1, laser welding machine welding does not require consumables, welding production costs are low.
2, laser welding machine energy concentration, high welding strength, firmness even more than the parent material.
3, laser welding machine laser beam is dense, heat-affected area is small, after welding the product is basically no deformation.
4, laser welding machine operation is simple, easy to get started, zero experience only two hours to start operating.
5, laser welding machine welding speed, the same time, a laser welding machine is five times the output of argon arc welding.
6, laser welding machine after welding seam beautiful, no burrs, no welding tumor welding scar, later use without grinding and polishing.
7, laser welding machine multi-purpose, can be replaced by cutting copper nozzle, temporarily used as a small power laser cutting machine.
8, laser welding machine gun head. For processing and welding manufacturers, welding the most important on four points, the difficulty of operation, welding speed, welding thickness and welding effect. Operation of the handheld laser welding machine undoubtedly accounted for a great advantage, welding speed is also more than five times the argon arc welding, welding effect of the overall laser welding machine, a small victory, but in the welding thickness of the laser welding machine is only suitable for welding sheet material, thick plate can not be welded through the same weldable thickness of the equipment, the laser welding machine price is significantly higher than the argon arc welding machine, which is a disadvantage of the laser welding machine.
In summary, the advantages of the laser welding machine is still very large, at present, by virtue of the fast speed in the field of thin plate, easy to operate, welding strength and other characteristics, and gradually replace most of the market argon arc welding machine market, in the field of thin plate welding is widely acclaimed.
