Arc Welding-Laser Shock Forging Process for Improving the Mechanical Properties of the Fe-Cr-C Cladded Layer

<div>(a) Optical macrograph of the Q235 steel pipe welded via AW-LSF (welding current of 110 A, welding speed of 140 mm/min, and laser shock frequency of 2 Hz), which illustrates the geometric characteristics. (b–d) Effects of the AW-LSF parameters on the weld height (<i>H</i>), bead width (<i>W</i>), penetration depth (<i>D</i>), aspect ratio (AR), and residual coefficient (RC). (b) Welding current. (c) Welding speed. (d) Laser shock frequency.</div>
