Resumo
Increasing automotive safety and energy efficiency have become the biggest concerns of the
automotive industry in recent years. The advanced high strength steel (AHSS) is chosen for the
weight reduction and high mechanical strength for the body in white (BIW) safe cage. The 22MnB5
press hardening type steel (PHS) patchweld technology allows to obtaining a reinforcements and
structural parts with one fie stamping stroke during hot forming. In the present study, adaptive
resistance spot welding control was using to keep consistent spot welding diameter. The resistance
spot welding esse evaluated using microhardness, tensile test and residual stress measurements.
The results showed that the 22MnB5 steel with galvanneled coating as received consisted of ferrite
and perlite after the resistance spot welding the fusion zone (FZ) has a lath martensitic structure
with higher hardness. The resistance spot welding showed a tensile strength reduction and
compression residual stress at the surface of the spot welding.
