Abstract
Overview
EN 29313:1992 (identical to ISO 9313:1989) specifies standard requirements for cooling tubes used in resistance spot welding equipment. The standard defines permissible diameters, cut-off angles and dimensional tolerances, and it establishes rules for to ensure interchangeability and reliable coolant flow. The tube end is cut at an angle to promote sufficient water flow to the welding electrode.
