ABSTRACT:
A material for welding5having a region11in which welding such as laser welding or arc welding is performed, the region including indentations5a-1which are produced by carrying out a first working step comprising embossing, V-bending, U-bending, L-bending, drawing, stepped drawing, or a combination of these to form a curved portion5ain the material being worked, and a second working step which is press working which crushes the curved portion5awhich is formed by the first working step. The indentations5a-1have a protruded portion11awhich projects from a flat surface which forms the surface of the material being worked5, and a recessed portion11bwhich is formed on the inside of the protruded portion11. Indentations5a-1are provided in the form of at least two separated dots so as to be generally parallel to the predicted welding position and are arranged on the expected welding position.
