what do welders do

Welders join metal parts using a tool that generates intense heat, typically through arc welding, which uses electrical currents to generate heat and bond metals. They work in a variety of industries, including construction, automotive manufacturing, and energy extraction. Welders read and interpret blueprints, sketches, and specifications, calculate and measure dimensions of metal parts to be welded, lay out, position, align, and secure metal parts, inspect workpieces for defects and check for specifications, ignite welding torches and strike arcs, select welding methods and required equipment, clean welded metal off excess weld, slag, or spatter, fill holes or hammer out bulges and bends, mix and apply protective coatings, and maintain equipment and machinery. They also follow strict safety regulations, including wearing the right safety gear. Welders may work outdoors in all types of weather, or they may work indoors, sometimes in a confined area.
