Abstract: The effect of laser welding on prevention of the fracture of cracked shafts of a high carbon steel are presented. Static tensile strength and rotary bending fatigue strength were obtained using ...

Abstract: This paper investigates the effect of laser hardening on cracked steel specimens. After laser hardening around precracked shafts of SAE 1015 steel, rotary bending fatigue strength was determined. ...

Abstract: This paper investigates the effect of laser welding on the prevention of fracture of cracked steel specimens. Precracks occurred in shaft specimens of SAE 1015 were welded by a CO2 laser, and ...
