Introduction
A weld bush is a type of fastener that is designed to be welded onto a workpiece. It is typically made of steel or another metal, and has a small, cylindrical head with a hollow, cylindrical body extending from it. Weld bushes are used in a variety of applications, including automotive manufacturing, construction, and appliance production. They are commonly used to attach components to a metal surface, and can be welded in place using a variety of welding processes such as shielded metal arc welding (SMAW), flux-cored arc welding (FCAW), and tungsten inert gas welding (TIG). Weld bushes offer several advantages over other types of fasteners, including high strength, corrosion resistance, and the ability to withstand high temperatures. They are often used in applications where it is necessary to maintain a smooth surface or to allow for the passage of fluids or other materials through the bush.
