Occupational Skills and Safety & Layout and Pattern Development

Welding and Joining Processes & Rigging, Hoisting, and Load Handling
Calculate weld metal volume and deposition rate for a given joint, then convert to arc time and total labor hours using an operating factor
Identify weld discontinuities from written descriptions (porosity, slag inclusion, lack of fusion, undercut, crater crack, lamellar tear) and state the process or handling cause and the correction
Compute the tension in each sling leg for a two-leg and four-leg bridle at a stated included angle, and state the capacity loss at 60, 90, and 120 degrees
Select shackles, hooks, and slings for a given load with the correct working load limit derating, and identify the inspection rejection criteria for each

A rigging and welding calculation package: one weld deposition and arc-time estimate, one four-leg sling tension calculation with a sketch, and a written rejection list for slings, shackles, and hooks
Rigging, Hoisting, and Load Handling & Pressure Vessels, Tanks, and Boilers
Plan a lift from scratch: determine load weight including rigging, locate the center of gravity, choose the hitch, verify crane capacity at radius, and list the exclusion zone and tagline plan
Explain the difference between a fired pressure vessel, unfired pressure vessel, and a power boiler in terms of code jurisdiction, inspection interval, and the fittings each must carry
Trace the water and steam path through a firetube and a watertube boiler and state the failure mode each design is prone to (overheating from low water, tube sheet cracking, caustic embrittlement, scale)
Identify the safety valve, relief valve, gauge glass, low-water cutoff, and try-cock functions and state the test each receives
Your checkpoint
A lift plan for one real or realistic load with weight, center of gravity, hitch, capacity check at radius, and exclusion zone, plus a labeled boiler component diagram naming at least eight fittings with their function and test
Pressure Vessels, Tanks, and Boilers & Structural Steel and Platework
Compute the required thickness of a cylindrical shell and a hemispherical head for given design pressure, allowable stress, joint efficiency, and corrosion allowance, and state the formula basis for each
Explain postweld heat treatment: when it is required by thickness and material, how temperature is measured and controlled, and what happens if the soak or cooling rate is wrong
Lay out and fit a beam-to-column connection and a stiffener plate using a tape, square, and level, and state the tolerance for square, plumb, and camber
Identify the structural shapes (W, S, C, HSS, angle, channel) and state how each is oriented for strong-axis bending and how holes are located from a gauge line

A pressure vessel shell and head thickness calculation with all inputs cited, plus a structural fit-up checklist covering at least eight tolerance and alignment checks for a beam-to-column connection
Structural Steel and Platework & Piping, Tanks, and Industrial Systems
Describe the sequence for erecting a structural bay: anchor bolts, column plumb, beam fit, temporary bracing, final bolt torque, and when temporary bracing may be removed
Explain pipe schedule, nominal size versus actual outside diameter, and how to select the correct flange rating, gasket, and bolt grade for a given service
Trace a piping system from source to use and identify where expansion loops, guides, anchors, and supports belong and why
State the alignment tolerances for a flange joint and the bolt tightening sequence for a four-bolt and an eight-bolt flange

Inspection, Testing, and Quality Control & Occupational Skills and Safety
Explain radiographic, ultrasonic, magnetic particle, dye penetrant, and visual testing in terms of what each detects, its limitations, and when each is specified
