70 kJ, 25 kV ELECTROMAGNETIC MANUFACTURING
EQUIPMENT (EME)

70 kJ, 25 kV Electromagnetic Manufacturing Equipment (EME) is the first Indian equipment based on indigenous technology. Electromagnetic manufacturing process is the state of art technology for shaping and joining of metals based on electromagnetic forming and electromagnetic welding. In these techniques, forming and welding are achieved without physical contact between tool and job piece.

SALIENT FEATURES

• It has obvious merits over conventional processes such as brazing, welding, expansion, contraction, contour formation etc., when used for some special applications.
• This sophisticated technique has many advantages such as precision, reproducibility, high production rate, no tool marks, minimization of manual error, automation ease, etc. The preparatory procedures such as preheating, lubrication, etc. are not needed.

APPLICATION

• Electromagnetic forming/welding of metal sheets.
• Tubular expansion and compression and welding of similar and dissimilar metals such as aluminum plugs to aluminum rod collapsed joints, Copper lug swaged on to the aluminum multi-core cable and aluminum plug collapsed on to SS-rod.
• Aluminum was found to be the easiest to weld and it was used as driver for achieving welds in other metal combinations.
• The EM welding technique has great potential in automobile, electric, defense, aeronautical and other industries.
