From the table shows that the plasma cloud size and the protective gas changes, the minimum helium, nitrogen, followed by argon. Plasma sizes, and the penetration depth is more shallow. The reason for this difference is first of all because of the different degree of ionization of the gas molecules, the other protective gas density caused by the metal vapor diffusion difference. Helium ionization minimum, the minimum density, it can quickly get rid of the metal vapor rising from the metal bath. With helium as the shielding gas, the maximum degree of inhibition of plasma, thereby increasing the penetration depth and welding speed; light can escape, it is difficult to cause stomata. Of course, from the effects of actual welding, argon protective effect is pretty good. green laser pointer can benefit the customer in every way. 
The advantages of deep penetration laser. Focused laser has a much higher power density than conventional methods, resulting in the welding speed, the heat affected zone and deformation are very small, can also be welded titanium and other materials difficult to weld. Because the beam is easy to transfer and control, does not require frequent replacement of the torch, nozzle, and no vacuum required for electron beam welding, a significant reduction in downtime auxiliary time, so the charge coefficient and production efficiency. Purification of the role and the high cooling rate, weld strength, toughness and high performance. Average heat input is low, high precision, can reduce the re-processing costs; In addition, the laser welding operation costs are lower, which can reduce the workpiece processing costs. green laser pointer is of the outstanding quality.
It is the three-in-one green laser pointer with wireless microphones
Can effectively control the beam intensity and fine mapping, and easy to automate. Laser deep penetration of the disadvantages. Limited welded depth. Workpiece assembly demanding. Higher one-time investment of the laser system. Laser cladding technology in the mold surface treatment. In modern production, the mold has become an important one of the technology and equipment for mass production of various industrial products and daily living products.
