... ( Ref 12.13 ). Provided the welding parameters are adjusted, DP, complex-phase (CP), and TRIP steels can be welded using conventional resistance spot welding processes on commercial spot welding machines. Laser welding of the three steels showed no particular difficulties or problems ( Ref 12.14...

... test to determine if the material is of the specified hardness. The approach for testing hardness is straightforward and is called a Rockwell hardness test. A hardened or diamond-tipped punch is pressed against the specimen surface with a known force to form a dimple. Softer materials have bigger...

... is to increase its second moment of inertia through corrugating or dimpling of the sheet metal. Corrugation or dimpling allows the reduction of thickness for weight savings without compromising stiffness ( Ref 4.2 ). Advanced high-strength steels offer greater design flexibility to optimize the stiffness...
