To investigate the spring-back behavior of dual-phase (DP) steel,V-shape spring-back experiments with different bending angles,relative bending radii and blank
Impact testing is a primary method to evaluate the impact property of resistance spot welding,which is an important quality index in automotive industry. For te
In this paper,the spot welding technology of a new kind of 22MnMoB hot stamping quenched steel sheet was systematically studied by power frequency spot welder.
