Laser Welding Aluminum Foil

In micro joining adjusting comparatively small gaps is a major challenge.

Laser welding aluminum foil.

Fiber laser welding services by accumet include welds of aluminum stainless steel kovar invar metal foils and alloys. Cutting aluminium foil redenergy g4 50w hs h. It can be seen that the tension shear loads are very low without aluminum interlayer in both single and dual beam laser welding joints. In the past aluminum s high reflectivity was a problem for laser welding.

This all happens within millionths of a second with impact speeds about. Vaporizing foil actuator welding vfaw uses the pressure from an electrically driven explosion to impact weld dissimilar metals at high speed. Here the welding of 100 µm thick aluminum foils in lap joints is investigated. There are several different types of lasers that work well with aluminum and often the use of a cover gas is prudent.

High brilliance lasers allow fast low heat deep penetration laser welding to produce narrow seams even in metal foils. Laser conduction welding lcw 10 6 w cm 2 is comparatively stable and may offer an alternative means of welding traditionally difficult materials such as aluminum alloys. It does this by changing a thin metal foil from a solid to a gas and using the pressure to push one base metal over a short controlled distance toward another base metal. Because of spattering and holes causing reduction of bearing area the hole and weld depression.

Gaps of 80 of the foil thickness were bridged. We are experts north of boston massachusetts in the field of welding steel and aluminum together and other dissimilar metals or hybrids and alloys. 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. Welded medical devices surgical tools dental plastics.

Advances in laser keyhole welding and investigations into its accompanying difficulties are well documented in the literature.
