Welding aluminum presents some unique challenges compared to welding steel or other common materials

ALUMINUM WELDING

The aluminum welding technology area has instructions, tips, and product information geared specifically toward welding this lightweight, versatile material.

Carbon dioxide laser is currently the most widely used laser with output power of 50 ~ 1500W, the wavelength of the laser beam is 10.6μm, mainly used for cutting, drilling and welding. Laser cutting may be at a speed of about 7.5m per minute, the cutting width of only 0.1 ~ 0.3mm, so that it can be cut, "heat affected zone" to minimize, and was cut out of the outline is clear, no glitches. As the laser drilling speed, and thus solve the problem in breakable ceramic on drilling, such as diamond in a thickness of 0.6mm diameter 1.3mm ceramic empty each time only 0.3S. Some countries have been replaced with carbon dioxide laser, electron beam welding equipment, laser welding may not necessarily be carried out in a vacuum so as electron beam, thus simplify the process and reduce costs. Solid state Nd - YAG laser into the industrial applications of time is relatively short, the output power of 10 ~ 400W, the laser beam wavelength of 1.06μm, easily absorbed by the metal material, currently used in low-power precision drilling and electronics industry The closure welding and spot welding process.
