Electromagnetic Impact Welding Of Aluminum To Stainless Steel Sheets

The welding cu to ss is accomplished by using al drivers to.

Electromagnetic impact welding of aluminum to stainless steel sheets.

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. The welding cu to ss is accomplished by using al drivers to accelerate cu and ss work sheets. Tensile shear strength of stainless steel aluminum sheets mpw joints. The tensile shear strength test and the metallographic studies are carried out for cu to ss em welds.

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

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. These properties make the welding of cu and cu alloys difficult as compared to welding of carbon steels. A study has been carried out to characterize the electromagnetic impact welding of 0 5 mm thick cu sheets.

The application of electromagnetic em impact technique is demonstrated for welding copper cu to stainless steel ss sheets. 13 shows the microstructural cracks of two welding specimens an aluminum alloy sheet and a galvanized steel sheet an aluminum alloy sheet and an ungalvanized steel sheet. Microstructure of the al to ss electromagnetically impact welded sheet shows continuous weld. 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 application of electromagnetic em impact technique is demonstrated for welding copper cu to stainless steel ss sheets. Kulkarni electromagnetic impact welding of aluminum.
