Compare Between Fiber Laser Cutting Machine & TIG MIG Welding
Can laser welding replace argon arc welding in an all-round way? Which is better, laser welding machine or argon arc welding? We are here to analyze it for everyone.
Laser welding machines can be divided into laser mold welding machines, automatic laser welding machines, laser spot welding machines, optical fiber transmission laser welding machines and other models according to their working methods. Laser welding uses high-energy laser pulses to micronize materials. Local heating in the area, the energy of laser radiation diffuses to the inside of the material through heat conduction, and the material is melted to form a specific molten pool to achieve the purpose of welding.
Here we compared the laser welding machine & TIG MIG welding from five aspects:
1. Welding speed: The welding operation of the laser welding machine is simple and fast, while the operation of argon arc welding is relatively difficult, and there are consumables, so the welding speed is relatively slow.
2. Welding depth: The laser welding machine melts and welds the material through the laser, but the laser is a short board in terms of deep welding. The cost of the laser welding machine is too high for the welded materials. For example: 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 to such a thick Stainless steel plates, but the cheap ones only cost a few hundred yuan. Therefore, if the penetration depth required to weld very thick materials is very deep, it is more appropriate to use argon arc welding.
3. Welding effect: The welding appearance of laser welding machine is more beautiful than that of argon arc welding, and laser welding 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 to 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.
4. Difficulty of operation: The operation of laser welding machine is much less difficult than that of argon arc welding. In fact, argon arc welding requires technology, skilled argon arc welding operators are required, and mistakes are also prone to occur. But laser welding is much better, the operation is simple, even if there is a mistake, it is not a big problem.
5. Environmental pollution: Laser welding has no harm to workers or the environment. Argon arc welding has a great impact on the environment, but because of the high heat and strong light generated during the welding process, it will have a certain impact or even harm on the workers' bodies.
Summary: It is better to use a laser welding machine for welding thin-walled materials, and it is better to use a laser welding machine for welding thick materials. Still better.
