Abstract
A fixing structure for a welding electrode and a welding head is shown which enable improvement of durability of a welding electrode, improvement of work efficiency in welding, and a reduction of time required for welding and also which make it possible to execute welding for an extended time with high reliability. In the fixing structure, a fixed section of a welding electrode is inserted via a thermally conductive material into an inserting section of a fixing base and a peripheral surface of the fixed section of the welding electrode is uniformly contacted to the fixing base to affix the welding electrode to the fixing base.
