METHOD FOR MANUFACTURING COMPONENT TO BE WELDED

PROBLEM TO BE SOLVED: To provide a method for manufacturing a component to be welded whereby the component after welding can be quickly gripped and transported.SOLUTION: A method according to the present invention includes: a joining process in which in a fuel cell 100, a steering member base material 91 and a component are brought into contact with each other at predetermined parts, and the contact parts are joined with each other by welding; and a transportation process in which a joined steering member 90 is gripped and transported. In the joining process, the steering member base material and the component are joined with each other at the parts which are above the steering member base material except a gravity center position b of the steering member, and in the transportation process, the gravity center position of the steering member above the steering member base material is gripped. 【課題】溶接後の部品を迅速に把持して搬送することができる溶接部品の製造方法を提供する。【解決手段】本発明に係る燃料電池１００は、ステアリングメンバ母材９１と部品とを所定の部位において接触させ、接触部位を溶接によって接合する接合工程と、接合されたステアリングメンバ９０を把持して搬送する搬送工程と、を有し、接合工程では、ステアリングメンバ母材上であってステアリングメンバの重心位置ｂを除く箇所においてステアリングメンバ母材と部品とを接合し、搬送工程においてステアリングメンバのステアリングメンバ母材上にある重心位置を把持する。【選択図】図１３
