Before you even think about welding, make sure you have the right gear, including fire resistant jacket, safety glasses, welding gloves and an approved welding helmet. Helmets have come a long way in recent years.
Welders plan how to do a welding project by following blueprints, specifications or work orders. They select and gather the materials they will need and lay them out. Then they begin to weld the parts together. Welders control the process by setting up the equipment and holding a welding gun (electric arc) or torch (gas), and concentrating the heat against the surfaces to be joined. A bond is made as material from a metal rod or wire melts to join and fill in the weld.
