Laser Welding Aluminum To Stainless Steel

Welding in thin stainless steel plate iron plate aluminum plate and other metal materials can.

Laser welding aluminum to stainless steel.

Using a bimetallic transition insert is the simpler and less expensive method of welding aluminum to steel. The heat affected zone is minimized and weld penetration can range up to 0 25 in aluminum. 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. 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. 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.

Fiber laser welding is the best way to weld steel and aluminum together. 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. There are 2 processes by which this is done. 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.

You can use basic welding knowledge with bimetallic transition inserts. This series of stainless steel is suitable for both pulsed and continuous wave cw laser welding. However the differences of thermal physical and chemical properties between aluminum and steel bring a series of problems in laser welding. The process is ideal for fast clean welds.

Welded medical devices surgical tools dental plastics. 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. It is an easy process that can be done without learning any extra techniques.
