Effect of boron content and welding current on the mechanical properties of electrical resistance spot welds in complex-phase steels.

Highlights: [•] Effects of the B contents on the peak load of the RSW in CP steels were examined. [•] The ND increased with increasing current regardless of the B contents. [•] Load in PF mode was affected by both the min. hardness and fractured diameter. [•] Load in IF mode was dependent only on the fractured diameter. [•] ND<5t 1/2 resulted in IF mode regardless of the B contents. [Copyright &y& Elsevier]
