Laser Welding Aluminum To Stainless Steel

You can use basic welding knowledge with bimetallic transition inserts.

Laser welding aluminum to stainless steel.

The heat affected zone is minimized and weld penetration can range up to 0 25 in aluminum. The other technique developed to replace the arc welding of aluminum to stainless steel is to coat the stainless steel in another substance that aluminum can be welded to. However the differences of thermal physical and chemical properties between aluminum and steel bring a series of problems in laser welding. The laser welding machine has the advantages are simple operation welding seam beautiful fast welding speed and no consumables.

In laser welding between cooper and stainless steel a major problem is the appearance of hot cracking in heat affected zone of the steel cracks induced by the diffusion of the copper into the grain boundaries of the unmelted steel. There are many advantages over arc welding and solid state diffusion or explosion welding. Welding in thin stainless steel plate iron plate aluminum plate and other metal materials can. Fiber laser welding services by accumet include welds of aluminum stainless steel kovar invar metal foils and alloys.

Fiber laser welding is the best way to weld steel and aluminum together. Laser welding stainless steel provides slightly better weld penetration depths and increased weld speeds when compared to low carbon steels due to the lower thermal conductivity of most austenitic stainless steels. This series of stainless steel is suitable for both pulsed and continuous wave cw laser welding. There are 2 processes by which this is done.

The methods used to bond these dissimilar materials and form the bimetallic transition are usually rolling explosion welding friction welding flash welding or hot pressure welding and arc welding. It is an easy process that can be done without learning any extra techniques. These inserts are best described as sections of material that are comprised of one part aluminum with an equal part steel or stainless steel already bonded to the aluminum. We are experts north of boston massachusetts in.

Using a bimetallic transition insert is the simpler and less expensive method of welding aluminum to steel. Laser beam welding is one of our most popular services for welding aluminum. Joining aluminum to steel can lighten the weight of components in the automobile and other industries which can reduce fuel consumption and harmful gas emissions to protect the environment.
