| Summary: | Resistance spot welding is one of the factors that determine the
crashworthiness of a vehicle. It is quite normal that in the automotive industry
the outer panel is being stoned using whetstone when the worker is trying to
find the defect at the panel. The aim of this study is to investigate the welding
quality and mechanical properties of 2 layer welding sheet containing a
reworked galvanneal metal sheet with HSS. Another set of material consisted
of non-reworked galvanneal metal and HSS were welded together as the
reference. The welded samples were prepared according to the ISO
14273:2000. Welding parameters for both types of samples were kept the same.
The tensile strength, hardness and microstructure of the welded material were
checked and the nugget diameters were compared tone another. Based on the
results, it was concluded that the rework process of the galvanneal metal sheet
did not change much the quality and the mechanical properties of the spot welding. |
