Welders need to prepare and finish joints in a wide range of industries and locations, from a factory workbench or construction site to a power station or ship at sea. Welders work with different metals to cut and join everything from steel beams to pipes, plates, and pressurized vessels. Being able to operate the various types of welding equipment both safely and accurately is of the highest importance. This can include the latest types of submerged arc, plasma arc, stud welding, and laser welding.
