Generally, the boilermakers cut, shape, assemble and weld structural steel and other metal stock to construct and repair metal products and structures. They are supposed to have adequate knowledge of materials, methods, and the required skill level to operate advanced tools involved in the construction of buildings and other structures, including boilers and pressure vessels.
A boilermaker has way more expertise than a regular welder. They are capable of assembling very big metal structures as well as small stuff, like handrails and building details, for exposed welds, and giving the product the perfect final touch it requires. Their confidence and tradesmanship comes with many years of welding experience in a variety of materials and structures.
As a veteran tradesperson, the boilermaker will have manual dexterity, static strength and great visualisation capabilities to carry out complex welding, fabrication and repair works. He should have the expertise and tradeskills for repairing, installation, quality control analysis, equipment maintenance, operations monitoring, and troubleshooting in a professional way.
