Boilermakers operate a variety of equipment and machinery to create, repipe and retube hot water and steam boilers, producing them in all steps of the production process. They cut, gouge and shape the metal sheets and tubes for the boilers to size, using oxy-acetylene gas torches, assemble them by shielded metal arc welding, gas metal arc welding or gas tungsten arc welding, and finish them by the approprate machine tools, power tools and coating.
