Electromagnetic Impact Welding Of Aluminum To Stainless Steel Sheets

Kulkarni electromagnetic impact welding of aluminum.

Electromagnetic impact welding of aluminum to stainless steel sheets.

The ability to manufacture a product using different metal combinations greatly increases flexibility in design and production. Tensile shear strength of stainless steel aluminum sheets mpw joints. To stainless steel sheets j. These properties make the welding of cu and cu alloys difficult as compared to welding of carbon steels.

2008 made similar kind of observations when they successfully joined 1 mm al sheet with 0 25 mm stainless steel ss sheets using an aluminium plate as a driver for ss sheet. The present study investigates the feasibility of electromagnetic impact welding of cu to cu sheets by using al as the driver sheet. The application of electromagnetic em impact technique is demonstrated for welding copper cu to stainless steel ss sheets. The magnetic field shaper that is placed between the metal components and an electromagnetic coil is used to concentrate the magnetic field around the weld zone and then enhance the generated lorentz force acting on the metal.

The objective of this work is to propose a magnetic pulse spot welding mpsw process with the aid of a field shaper for achieving the connecting of metal components. 2014 developed an electromagnetic weld pool support system for high power. The application of electromagnetic em impact technique is demonstrated for welding copper cu to stainless steel ss sheets. The welding cu to ss is accomplished by using al drivers to accelerate cu and ss work sheets.

Microstructure of the al to ss electromagnetically impact welded sheet shows continuous weld. Stainless steel sheet of 0 25 mm thickness can be accelerated with the use of the aluminum driver sheet and welded to 1 mm thick aluminum sheet by electromagnetic impact welding at capacitor discharge energy of 4 09 kj. The welding cu to ss is accomplished by using al drivers to. The tensile shear strength test and the metallographic studies are carried out for cu to ss em welds.

These cracks were only found on the interfacial diffusion zone containing aluminum element iron element and zinc element. Joining of dissimilar metal combinations like copper to stainless steel cu to ss is however a challenging task owing.
