Abstract:
In this study, the effects of weld current, weld time, electrode force and combination of these on the nugget diameter, heat affected zone and tensile-strength of welding joint in electrical resistance spot welding of AISI 304 sheets of 1mm thickness are investigated. A timer and current controlled pneumatically operated rocker arm type spot welding machine of 10 kVA capacity with pneumatic application mechanism and foot switch, with controls for weld current periods, weld time periods and electrode force is used. Squeeze time is kept constant throughout the process at 40 cycles. The obtained welded joints are subjected to tensile-shear strength. Nugget diameter and heat affected zone (HAZ) are observed and computed. The effect of weld current, weld time and electrode force on nugget diameter, HAZ and tensile-shear are then researched by regression modeling and by related diagrams. Optimum weld current, weld time and electrode force for various configurations are thus arrived at.
