Welders join metal parts together using various welding techniques including MIG, TIG, stick welding, and flux-cored processes. The work spans construction, manufacturing, shipbuilding, aerospace, pipeline, and repair industries. Welders read blueprints, calculate dimensions, inspect structures for defects, select appropriate materials and methods, prepare metal surfaces, operate welding equipment, and verify weld quality through visual inspection and testing. Advanced positions involve welding exotic metals, working on pressure vessels, or performing structural work requiring certification to specific codes. Work environments vary dramatically—from climate-controlled fabrication shops to outdoor construction sites, underwater structures, and confined spaces. Physical demands include prolonged positioning, exposure to heat and fumes, and wearing protective equipment. Career advancement includes specialized certifications, inspection roles, and welding engineering positions.

Pipefitters install and maintain piping systems that carry chemicals, acids, gases, and other materials in industrial and manufacturing settings, often involving high-pressure and high-temperature systems. The work requires reading blueprints, cutting and threading pipe, fitting and welding components, testing systems for leaks, and ensuring compliance with safety codes. Pipefitters work in power plants, refineries, chemical facilities, pharmaceutical manufacturing, shipyards, and commercial buildings. Systems include steam, compressed air, hydraulics, process piping, and fire suppression. The work demands precision—systems carry hazardous materials or operate under extreme conditions where failures have serious consequences. Specialized knowledge includes different pipe materials, fitting methods, and code requirements for various applications. Physical demands include working in industrial environments, confined spaces, and elevated positions.

Ironworkers install structural and reinforcing iron and steel to form buildings, bridges, and other structures. The work encompasses unloading and positioning steel beams using cranes and rigging equipment, connecting beams with bolts or welding, installing metal decking, placing reinforcing bars (rebar) in concrete forms, and erecting precast concrete components. Structural ironworkers assemble the steel frameworks of high-rises, bridges, and industrial facilities, often working at extreme heights on narrow beams. Reinforcing ironworkers position and secure the rebar that strengthens concrete structures. The job requires reading blueprints to understand how pieces fit together, operating rigging equipment to position heavy steel precisely, and working safely in inherently dangerous conditions. Physical strength and stamina are essential for handling heavy materials in demanding positions. Ironworkers develop expertise in specific structural systems—some specialize in bridge work, others in high-rise construction, and still others in ornamental iron that combines structural function with architectural aesthetics.
