UHV compatible Al to SS joining through electro magnetic forming technique

Abstract

Fusion welding, which is the most versatile and widely used method of metallurgical bonding, can be troublesome in certain applications like dissimilar metal joining for Ultra High Vacuum requirements. Welding of Stainless Steel to Aluminum by conventional technique is very difficult due to thermal & metallurgical incompatibility. Consequently a number of non-conventional specialized joining techniques were developed. Joining of SS to Al by Electro Magnetic Forming (EMF) method is an effort in this direction. The paper discusses in detail the joining process, joint design and the results achieved.

Magnetic pulse welding on the cutting edge of industrial applications

“…It was observed [28] that under high strain rates, aluminium ductile behaviour increases, which facilitates magnetic welding similarly to Ti alloys that exhibit excellent corrosion resistance associated to high mechanical resistance. Magnesium alloys is gaining interest in the automotive and aeronautic industries, mainly, because of their high weight to resistance ratio since Mg is the lightest structural material [28,29,30]. It has been tested under high velocity welding technologies, and MPW is feasibility in Mg alloys [30] where ductility and formability increase at high strain rates.…”

Research Progress on Control Strategy of Intermetallic Compounds in Welding Process of Heterogeneous Materials

“…Prasad et al [ 93 ] used electron beam welding technology to conduct welding experiments on steel and Al alloy. It studied the effect of the coil shape on the performance of the joint.…”
