F. Planning and Authorization

1. Select the approved capstone design before material procurement. Confirm the design matches the preferred or alternate option described in this chapter.
2. Confirm the project is noncritical and not intended for lifting, structural support, fall protection, vehicle restraint, pressure, trailers, overhead loads, or public safety. Record this confirmation on the traveler.
3. Obtain the current shop drawing, revision, material list, cut list, weld symbols, tolerances, finish, intended use, and load limit. Confirm the document set is complete before proceeding.
4. Review the drawing for missing dimensions, conflicts, inaccessible welds, unstable geometry, and unclear scope. List every open question.
5. Resolve drawing questions before cutting. Obtain answers from the responsible instructor or qualified evaluator and record the resolution on the traveler.
6. Select the approved SMAW or GMAW process and procedure. Confirm the process matches the equipment and consumables available at the station.
7. Identify the responsible instructor or qualified evaluator. Record the name on the traveler.
8. Prepare the hot-work permit or approved shop authorization. Confirm it covers the location, duration, and process planned for this capstone.
9. Create the work-area, fire-watch, ventilation, PPE, cylinder, electrical, and emergency plan. Base this plan on the Chapter 1 readiness practice.
10. Inspect and document the welding area. Repeat the Chapter 1 readiness walk-through for this session.
11. Inspect and document PPE. Repeat the Chapter 2 PPE inspection.
12. Inspect and document the welding machine, leads, clamp, holder or gun, gas system, and consumables. Repeat the Chapter 3 equipment-readiness inspection.

G. Material Verification and Part Preparation

1. Verify material identification, grade or type, thickness, size, and condition. Compare every piece of stock against the approved material list.
2. Reject unknown, cracked, heavily pitted, contaminated, or prohibited coated material. Do not substitute unidentified stock.
3. Create a part traveler with identifiers for every component. Assign each identifier before cutting begins.
4. Lay out parts from a single reference edge. Establish the assembly baseline described in Reference Conventions.
5. Verify all cut dimensions before cutting. Check every marked line against the cut list.
6. Set up stock supports, clamps, stops, screens, and spark controls. Confirm the cutting area meets the Chapter 5 setup standard.
7. Cut parts using approved hand, saw, or abrasive methods. Select the tool approved for each cut per Chapter 5.
8. Control drop pieces and hot material. Direct cut and drop pieces into the marked hot-metal zone.
9. Deburr all handling edges. Remove burrs from every cut part before further handling.
10. Prepare bevels or joint edges only where shown. Do not add a bevel or edge preparation not called out on the drawing.
11. Remove rust, scale, oil, paint, and contamination from weld and clamp zones. Clean every part to bright metal in the weld and work-clamp areas.
12. Measure and inspect every finished part. Record dimensions on the traveler against the cut list.
13. Remake parts outside approved tolerance. Do not carry an out-of-tolerance part into assembly.

H. Fit-Up, Clamping, and Tack Welding

1. Arrange parts in assembly order. Confirm every part identifier matches the traveler.
2. Clean the welding table, fixtures, squares, clamps, and stops. Remove residue that could affect fit-up or grounding.
3. Establish the assembly baseline and origin. Mark it clearly on the table.
4. Lay out the first frame section. Position parts against the baseline and any stops.
5. Clamp parts without lifting or twisting them. Confirm parts remain flat against the table.
6. Check length, width, angle, square, and diagonals. Compare against the drawing tolerance before continuing.
7. Install spacers, stops, or fixtures needed for repeatable geometry. Confirm these do not shift under clamp pressure.
8. Confirm access for all required welds. Check every joint on the weld map against the electrode, gun, or torch angle needed.
9. Attach the work clamp to clean sound metal close to the weld area. Confirm the clamp path avoids bearings, hinges, or unintended components.
10. Set and record machine polarity, consumable, gas, voltage and wire speed, or amperage as applicable. Record the settings on the traveler.
11. Run a parameter-verification bead on matching scrap. Use stock of the same material and thickness as the assembly.
12. Inspect the test bead and obtain approval. Do not proceed to tacking without an accepted test bead.
13. Place tack welds in the approved balanced sequence. Follow the sequence marked on the traveler.
14. Inspect each tack for cracking, porosity, fusion, crater, and size. Reject any tack outside the approved condition.
15. Remove and replace unacceptable tacks. Use the approved repair method before continuing.
16. Recheck overall dimensions, diagonals, angles, gaps, and flatness. Compare against the drawing tolerance after tacking.
17. Correct fit-up before final welding. Do not proceed to final welding with an out-of-tolerance tacked assembly.
18. Mark the final welding sequence on the traveler. Confirm the sequence balances heat input across the assembly.

I. Final Welding and Distortion Control

1. Begin final welding with short balanced segments where specified. Follow the sequence marked on the traveler.
2. Maintain approved electrode or gun angle, arc length or stickout, travel speed, and puddle control. Apply the technique standards from Chapters 7 through 13.
3. Clean slag or contamination between weld segments and passes. Do not weld over uncleaned slag or contamination.
4. Monitor heat buildup and machine duty cycle. Pause welding if the machine or assembly approaches its limit.
5. Alternate sides or locations according to the distortion-control plan. Do not weld one side of the assembly to completion before starting the opposite side.
6. Do not quench the assembly unless the approved procedure permits it. Allow natural cooling between segments.
7. Pause and remeasure critical dimensions during welding. Check length, width, diagonals, and squareness at the planned checkpoints.
8. Stop for excessive movement, cracking, unstable fixturing, gas loss, electrical fault, or fire-control failure. Correct the condition before resuming.
9. Complete all required welds without adding unauthorized weld length or size. Weld only the joints and lengths shown on the weld map.

J. Cooling, Dimensional Check, and Cleaning

1. Allow controlled cooling in the designated area. Mark the assembly hot until it is verified safe to handle.
2. Release clamps gradually and observe spring movement. Note any shift as clamps are released.
3. Measure final length, width, height, diagonals, angles, level, square, and flatness. Record every value on the traveler.
4. Record distortion and compare it with tolerance. Identify whether any dimension exceeds the drawing tolerance.
5. Remove slag and spatter. Clean every weld and adjacent surface.
6. Clean every weld for inspection. Confirm toes, starts, and stops are visible under adequate lighting.

K. Weld Inspection and Repair

1. Inspect weld location, length, size, profile, toe fusion indicators, undercut, overlap, porosity, crater, starts, stops, arc strikes, and cracks. Use the Chapter 18 defect-identification criteria.
2. Use approved weld gauges. Measure fillet size, length, and reinforcement against the acceptance standard.
3. Mark accepted, repair, and review locations on the weld map. Record the status of every weld individually.
4. Prepare a qualified corrective-action plan for approved repair items. Identify the probable cause before repairing.
5. Remove defects without reducing required section thickness. Use the approved excavation method.
6. Reweld and reinspect repaired areas. Confirm the repaired weld meets the original acceptance standard.

L. Finishing and Function Check

1. Deburr sharp edges and corners. Remove handling hazards from the completed assembly.
2. Grind only surfaces shown by the drawing or finish specification. Do not grind a weld flush unless the drawing permits it.
3. Clean the entire assembly for coating. Remove oil, dust, slag, and abrasive residue.
4. Apply the approved primer, paint, oil, or finish under required ventilation and cure conditions. Follow the manufacturer's cure and ventilation instructions.
5. Do not coat unaccepted welds. Confirm every weld is marked accepted before coating.
6. Inspect finish coverage and cure. Confirm the coating is complete and cured before handling.
7. Perform only the approved noncritical stability and function check. Use the check defined by the drawing or instructor.
8. Do not proof load beyond the stated test or use limit. Stop the function check at the defined limit.
9. Attach a permanent or durable project identification and use-limitation label where required. Confirm the label states the noncritical use and load limit.

M. Documentation and Closeout

1. Complete the material, cut, fit-up, tack, parameter, weld, repair, dimension, finish, and inspection records. Confirm every field on the traveler is filled in.
2. Compile the drawing, traveler, photographs, machine setup, consumable information, inspection form, and finish data. Assemble the complete capstone record.
3. Shut down the welding machine. De-energize and secure the station.
4. Close and secure gas cylinders. Confirm valves are closed and cylinders are upright and secured.
