Abstract
PURPOSE:To prevent generating cracks and exfoliations on padding parts at bending by forming plural welded padding parts divided by grooves on a surface of metallic base in the bending area. CONSTITUTION:The welded padding layer 20 divided by narrow grooves 30 is formed on the surface of the metallic base 10 for forming a composite member. In this case, the grooves 30 are formed elongating in the direction of the generating lines of an arc surface at the bending work. Then, when a flat composite member is bending worked to form the arc through a press work, etc., the grooves 30 are changed from open states before bending worked to almost closed states. Groove widths (g) are usually set under the layer thickness (t) of the padding layer 20. In this way, the grooves 30 are brought into closed states, the padding layer 20 is formed to a continuous surface. Therefore, in the stage of performing the bending work into a small radius (R), generating the cracks and exfoliations on the welded padding layer 20 are prevented.
