Home / What are the manufacturing processes for cold-joints
In general, cold-formed sections are suitable for welding and joints can be made by the open arc process as well as by resistance welding. The principle of the open arc welding is a heat input by an electrical open arc which is being stricken between an electrode and a. The various processes that fall under the category of mechanical joining are all cold forming techniques that either work with or without a fastener. Cold forming, also known as cold heading, is the process of forming a fastener without heating up the material.
