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, and they often read blueprints to understand project specifications. Safety is a crucial aspect of welding, as the process involves intense heat and bright light. Welders wear protective gear, such as helmets, gloves, and flame-resistant clothing, to shield themselves from sparks and harmful radiation. Proper training and certification are essential for welders to ensure quality work and maintain safety standards.
