Effect of AlSi coating on laser spot welding of press hardened steel and process improvement with annular stirring

Laser spot welding method was employed to fabricate AlSi coated press-hardened steel (PHS) joints in overlapped configuration. Al and Si segregate at the notch root of a laser spot weld of AlSi coated PHS resulting in pre-mature cracking and weakening of the joint strength. The thickness-oriented...
