Laser Welding Aluminum To Stainless Steel

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.

Laser welding aluminum to stainless steel. You can use basic welding knowledge with bimetallic transition inserts. 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. The main problems are how to control the thickness of the. It is an easy process that can be done without learning any extra techniques.

Welded medical devices surgical tools dental plastics. Fiber laser welding is the best way to weld steel and aluminum together. 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. We are experts north of boston massachusetts in.

The heat affected zone is minimized and weld penetration can range up to 0 25 in aluminum. Support updates get a quote about services overview. 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. Fiber laser welding services by accumet include welds of aluminum stainless steel kovar invar metal foils and alloys.

However the differences of thermal physical and chemical properties between aluminum and steel bring a series of problems in laser welding. There are many advantages over arc welding and solid state diffusion or explosion welding. The process is ideal for fast clean welds. There are 2 processes by which this is done.

Welding in thin stainless steel plate iron plate aluminum plate and other metal materials can. 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. Using a bimetallic transition insert is the simpler and less expensive method of welding aluminum to steel. 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.
