PROBLEM TO BE SOLVED: To provide a component discrimination method in welding which allows an operator welding one component with the other component to discriminate right and wrong of the one component, easily and accurately at low costs, through visual observation in a short time and a welding method which enables the discrimination and is applicable to components affecting the appearance and strength.SOLUTION: In welding one component 11 to the other component 12 temporarily, right and wrong of the one component 11 is discriminated through a concave part 13 formed in a to-be-temporarily-welded part. The part in which the concave part 13 of the one component 11 is welded temporarily with the other component 12 to fill the gap of the concave part 13. A root part penetration is secured with the temporarily welded part 14; the one component 11 is welded finally with the other component 12; and the concave part 13 is filled completely with the finally welded part 15. |
