FAQ
- What weld inspection is required in a steel ITP?
- Weld inspection requirements depend on the weld category specified in AS/NZS 1554. Category SP (Structural Purpose) welds typically require 100% visual inspection and a specified percentage of NDT (Non-Destructive Testing) — usually ultrasonic or magnetic particle testing. The ITP should specify the NDT method, acceptance criteria, and the hold point for inspection before the weld is covered or coated.
- What hold points apply to bolt tensioning?
- Bolt tensioning is a critical hold point because under-torqued bolts compromise connection capacity, and over-torqued bolts can cause bolt failure. The ITP should include a hold point at bolt tensioning verification, with the inspection recording the torque method (turn-of-nut, direct tension indicator, or calibrated wrench), the target torque value, and the inspector's sign-off.
- Do structural steel ITPs cover both fabrication and erection?
- They can, but it's common to have separate ITPs for fabrication (workshop) and erection (site). Fabrication ITPs cover cutting, fit-up, welding, and surface prep. Erection ITPs cover delivery inspection, alignment, bolting, and site welding. For simpler projects, a combined ITP works fine.
