Which weld process uses no consumables?

Explanation:
Non-consumable electrode welding relies on an electrode that does not melt away during the weld. In TIG welding, the electrode is tungsten, which stays intact while the arc heats the workpiece. Shielding gas protects the weld, and filler metal can be added separately if the joint needs it, or you can weld with no filler metal at all. Since the electrode itself isn’t consumed and you can complete the weld without inserting filler metal, this process uses no consumables from the electrode side. This is different from methods that rely on a consumable electrode or filler wire that melts away to form the weld.
