“…Some of the differences of RMW include the following: substantially lower forces and currents, nonferrous materials are often welded, electrode cooling is not possible and much faster cooling rates exist. 1,[14][15][16] Many investigations into the bonding mechanism and dynamic resistance during the RMW of similar non-ferrous thin plates and fine wires have been performed. 1,4,6,9,[13][14][15][16][17][18] Zhou et al 14 and Ely and Zhou 16 were the first to investigate the differences in RMW compared to LSRSW and outline the recommended process parameters to join thin Al, brass, Cu, Kovar, steel and Ni sheets.…”

The bonding mechanisms have been shown to change with material properties and process parameters for similar material joints, including those of crossed wire geometry.…”

Resistance microwelding of dissimilar materials such as Pt-10Ir and 316 low carbon vacuum melted stainless steel is becoming increasingly important for making electrical connections in medical devices. The joining of dissimilar materials increases flexibility in design while providing economic advantages, where more cost effective materials can be substituted for traditional materials. In this work, the performance of joints made using different electrode forces was studied by examining the surface morphology, cross-sections, joint break force and dynamic resistance measurements from resistance microwelding joints. Electrode sticking and excessive expulsion were observed with low electrode forces, whereas joints with undesirable cracks and notches were produced at higher electrode forces. Based on the analysis of single pulse welds, a new process variation using multiple pulses was developed, which improved the weld surface quality while obtaining a joint strength near 90% of the Pt-10Ir wire tensile strength.
