Laser Oscillating of Nickel Alloyed Welds on Press-Hardened Steel [PDF]
Chinese Journal of Mechanical Engineering, 2021 Abstract Laser oscillating welding was employed to fabricate Al-Si coated press-hardened steel (PHS) to improve the element homogeneity in the fusion zone. Laser oscillating welding was employed with various oscillation amplitudes (0 mm, 0.5 mm and 1.3 mm) in this present. Ni foil of 0.06 mm thickness was used as an interlayer between
