Welders are skilled tradespeople who join metal parts together using heat and pressure. They use various techniques, such as MIG welding, TIG welding, and stick welding, to create strong and durable connections. Welders work in many industries, including construction, manufacturing, and automotive, where they help build and repair structures and machinery. To perform their job safely and effectively, welders wear protective gear, including helmets, gloves, and flame-resistant clothing. They must also understand blueprints and technical drawings to ensure precise work. The role of a welder is essential in creating everything from bridges to automobiles.
