- Read blueprints and drawings and take or read measurements to plan layout and procedures
- Determine the appropriate welding equipment or method based on requirements
- Set up components for welding according to specifications (e.g. cut material with powered saws to match measurements)
- Operate angle grinders to prepare the parts that must be welded
- Align components using calipers, rulers etc., and clamp pieces
- Weld components using manual or semi-automatic welding equipment in various positions (vertical, horizontal or overhead)
- Cut, thread, and hammer pipe to specifications, using tools such as saws, cutting torches, and pipe threaders and benders.
- Assemble and secure pipes, tubes, fittings, and related equipment, according to specifications, by welding, brazing, cementing, soldering, and threading joints.
- Attach pipes to walls, structures and fixtures, using brackets, clamps, tools or welding equipment.
- Inspect, examine, and test installed systems and pipe lines, using pressure gauge, hydrostatic testing, observation, or other methods.
- Measure and mark pipes for cutting and threading.
- Select pipe sizes and types and related materials, such as supports, hangers, and hydraulic cylinders, according to specifications.
- Cut and bore holes in structures, such as grating, walls, and mains, prior to pipe installation, using hand and power tools.
- Modify, clean, and maintain pipe systems, units, fittings, and related machines and equipment, following specifications and using hand and power tools.
- Inspect work sites for obstructions and to ensure that holes will not cause structural weakness.
- Install automatic controls used to regulate pipe systems.
- Turn valves to shut off steam, water, or other gases or liquids from pipe sections, using valve keys or wrenches.
