In many welding processes, laser welding has high efficiency and high precision, but laser welding inevitably produces welding fumes. At this time, Pure-Air laser welding fume filters are needed!

Laser welding uses high-energy-density laser as the heat source to irradiate the joints of materials, so that the separated materials will quickly melt and even vaporize after absorbing the laser energy to form a molten pool, and then solidify together to connect together in the subsequent cooling process. There are two common high-power lasers for laser welding: CO2 laser and solid/fiber laser. The wavelength of the former is μm or the wavelength is μm, both of which are in the infrared band and are invisible to the naked eye.

The common welding principle is actually to liquefy the metal, and then melt it together after cooling. The car body is welded by four steel plates up, down, left, and right. Common welding is spot welding, and the steel plates are connected together by welding points one by one. The two pieces of material are still not welded together.

However, laser welding is a physical principle that uses the high temperature of the laser to disrupt the molecular structure of the two steel plates, and the molecules are rearranged to make the molecules in the two steel plates melt into one. The actual operation is to use a polarizer to reflect the light beam generated by the laser, so that it is concentrated on the focusing device to generate a huge energy beam. Therefore, laser welding turns two steel plates into one steel plate, so it has higher strength than ordinary welding.

Pure-Air, the laser welding fume filter, effectively purifies the smoke and odor in the welding workshop, so that the workshop is free of smoke and dust pollution, and the workshop production efficiency is greatly improved, providing higher production efficiency for laser welding enterprises!
