Spot Weldability Comparison of High Strength Steel BIF340 and Normal Cold-Rolled Steel St14

Abstract:

The experimental investigation was carried out to compare resistance spot weldability of BIF340 and St14 steel in different weld processes.The spot weld microstructure and properties of two steels were analyzed.The results shown that : resistance spot weldability of BIF340 is better than St14.The optimum parameters of BIF340 were as follows: welding current was 6KA,welding time was 7 cycles, electrode force was 2800N. With the same welding process parameters, the microstructure of BIF340 spot weld was homogeneous and fine-grained, and the tensile shear strength was higher than St14.
