Structural Steel Built-Up Section Fabrication Inspection

This template covers fabrication checks for welded built-up steel members, including document control, material preparation, fit-up, web and flange weld quality, splice welds, dimensional accuracy, surface condition, marking, and final sign-off. It is designed for shop QC or receiving inspection before the member is released to erection. The checklist is specific to fabricated built-up sections, not general structural steel or field erection work.

Use it during fabrication after fit-up and welding, and again before final release if repairs or rework were made. It is especially useful for members with critical splice welds, camber or twist tolerances, or traceability requirements. Do not use it as a substitute for in-process welding controls or separate nondestructive testing records.

A qualified QC inspector, fabrication supervisor, or designated inspector familiar with the shop drawing, WPS, and acceptance criteria should complete it. For hold points or critical members, the inspection may also involve a third-party inspector or customer representative. The person signing should be able to verify both visual condition and dimensional conformance.

Yes, it supports quality control practices used alongside OSHA general industry and construction requirements, ANSI/ASSP fabrication and safety programs, and applicable AWS structural welding practices. If the project has owner, engineer, or code requirements, those acceptance criteria should be added to the template. The checklist itself is not a code citation, but it helps document conformance to the governing fabrication standard.

Common misses include using the wrong material grade or thickness, incomplete fit-up at the splice, weld discontinuities left in place, and members that are out of straightness or twist tolerance. Inspectors also often find missing heat numbers, illegible piece marks, or cleanup work that has reduced section capacity. Those issues are easier to correct in the shop than after shipment.

Yes, and you should. Built-up section tolerances, weld acceptance limits, NDT requirements, and marking rules often vary by project specification, engineer of record, or customer standard. Add the exact tolerance values, hold points, and repair approval workflow so the checklist matches the released fabrication package.

Use it for each built-up section or fabrication lot, and repeat it after any repair that affects welds, alignment, or dimensions. For repetitive production runs, many shops use it as a final QC gate on every member and a sampling review for in-process checks. If a member is designated critical, inspect it at every required hold point.

An ad-hoc walkthrough is easy to miss because it depends on memory and informal notes. This template gives you a repeatable sequence that ties the inspection to the shop drawing, WPS, traceability, dimensional checks, and final disposition. That makes it easier to prove what was checked, what failed, and what was repaired.

Record the deficiency, identify the affected member and location, and route it through your repair or disposition process before release. If the issue affects weld integrity, alignment, or section capacity, require re-inspection after corrective action. Do not close the inspection until the repair status and final acceptance are documented.
