The heat treatment processes that been used in this experimental are annealing, normalizing and quenching. Two pieces of low carbon steel plate were welded together as lap joint by using resistance spot welding. The joints were produced using different welding current which were 2 kAmp, 4 kAmp, and 6 kAmp with difference cycles starting from 2, 4 and 6 cycles.

Microscopic analysis was used to get the microstructures to achieve the each heat treatment structure. The properties that obtained are correlate with the effect of varies welding currents and cycles. From the result obtained, it was found that the maximum load of tensile shear test increases as the welding current and cycles increased. For the hardness distribution analysis, the increasing welding current and cycles do not give a major influence difference on the of hardness distribution of the welds where the area of HAZ in each samples show the high values. There was also found that the increasing welding currents and cycles increased the weld diameters. 2008-11-27T02:50:05Z 2008-11-27T02:50:05Z 2008-04 Learning Object http://hdl.handle.net/123456789/3358 en Universiti Malaysia Perlis School of Materials Engineering
