The advantages and disadvantages of laser welding machine and argon arc welding are compared from four aspects:
Simply use spot welding machines and automatic welding machines to classify. The welding operation of laser spot welding machines is simple and the welding speed is fast. The operation of non-melting electrode argon arc welding is relatively difficult, and there are consumables, so the welding speed is relatively slow.
The welding speed of automatic laser welding machine and automatic MIGA welding is not very different, but because MIGA welding still needs to melt the welding wire, the welding speed will still be slightly slower than that of automatic laser welding machine.
Laser welding machines use lasers to melt and weld materials, but lasers are a shortcoming in terms of deep welding. It's not that laser deep welding is not good, but that the cost is too high.
If you need to weld a 2.0mm stainless steel plate, if you use a laser welding machine, you must use a 500W optical fiber transmission laser welding machine at least, the price is about 100,000, and the argon arc welding machine can generally weld such a thick stainless steel plate , but the cheap one is only a few hundred yuan, and the automatic argon arc welding is only 20,000 to 30,000 yuan. Therefore, if the penetration depth required to weld very thick materials is very deep, it is generally not cost-effective to use a laser welding machine.
The welding appearance of spot laser welding machine is more beautiful than that of non-melting electrode argon arc welding, the welding appearance of automatic laser welding machine and automatic argon arc welding machine is similar, and the welding appearance of thin material welding is better. In terms of welding firmness, as long as the power of the laser welding machine is large enough, it can weld very firmly, which is comparable to argon arc welding.
However, the heat of the laser welding machine is more concentrated, and the thermal deformation caused by the material is small, so the laser welding machine has more advantages in welding thin-walled materials. In terms of precision, the precision of the laser welding machine is also higher, and the laser welding machine basically does not need to do other processing after welding, which saves time and trouble.
The operation of laser spot welding machine is much less difficult than that of non-melting electrode argon arc welding. In fact, argon arc welding is very technical, requires skilled argon arc welding operators, and is also prone to mistakes, but laser welding is much better, the operation is simple, even if there is a mistake, it is not a big problem.
The operation of automatic laser welding and automatic argon arc welding is not difficult, and both require computer control.
Laser welding has no harm to workers or the environment. Argon arc welding has little impact on the environment, but because of the high heat and strong light produced during the welding process, it will have a certain impact or even damage to the workers' health.
