This is a job that goes deep into factories and industrial settings. As a Pressure Systems Welder, you will use all kinds of welding—like shielded metal arc, gas metal arc, gas tungsten arc, flux cored arc—to weld metal plates, shells, tubes, drums, and other structures in boilers and pressure systems to assemble and repair them. You will also cut pipes and tanks and assemble these pieces, and repair defective welds in boilers and pressure systems.
