Laser Welding Aluminum Sheet

The rws uses a high powered co 2 laser beam to apply energy and weld sheet metal components.

Laser welding aluminum sheet.

From a remote location the laser beam is focused by a long focal length lens. Yag laser was used as the welding laser while an auxiliary continuous wave diode laser was used as a pre heating source in lap welding of two 50 µm aluminum sheets. The light beam is highly collimated and can be focused to result in weld widths about three times the aluminum sheet thickness. Typical sheet thicknesses for heat conduction welding with a 3 kw laser are approximately 3 mm 120 in for steel and 2 5 mm 100 in for aluminum due to the material s high reflectivity and thermal conductivity.

In the past aluminum s high reflectivity was a problem for laser welding. Typical applications are for example the joining of tailored blanks in the automotive assembly or thick sheet welding. Laser welding has come of age and is now successfully used in industry for the welding of both coated and uncoated steel sheet. Laser welding makes the cut nu way ultimately turned to laser technology for the joining job.

Welding in thin stainless steel plate iron plate aluminum plate and other metal materials can perfectly replace the traditional argon arc welding and electric welding technology. The word laser means light amplification by stimulated emission of radiation. It has become an established joining technology for a range of joint configuration and automotive applications including tailored blanks and body assembly. Laser beam welding can be used with crack sensitive materials such as the 6000 series of aluminum alloys when combined with an appropriate filler material such as 4032 or 4047 aluminum.

Laser energy is developing as a production process for welding and cutting metals. Dual beam laser welding of aluminum and laser welding of zinc coated steel were performed. The quality and performance of thin sheet metal joints. There are several different types of lasers that work well with aluminum and often the use of a cover gas is prudent.

Laser welding systems are the prerequisite for efficient optimized and productive sheet metal processing high welding speeds through automated welding technology weil technology s laser welding systems can be configured on the basis of standardized modules which allows for the development of component customer and project specific production systems. With laser welding the maximum sheet thickness depends on the welding technique as well as the material.
