The Importance of Inspection and Test Plan (ITP) Before Any Welding Procedures

19 November 2021

Welding and manufacturing works are unquestionably imperative to the uprightness of construction, building and task. A deformity or issue which is ignored or missed in light of careless inspection and test process is deemed a conceivably risky or calamitous danger already in the works.

This is why organisations and regulatory boards require welding and manufacturing inspection and test plans (ITP). The same ITP’s are utilised by the organisations leading the inspections and tests. They use ITPs to check the record-keeping and guarantee that they have proof of the nature of work and the care they took in directing their work.

An Overview of Inspection and Test Plan (ITP)

Before manufacturing, the buyer should receive a hardware inspection and a test plan (ITP) from the manufacturer. The ITP distinguishes all inspection focuses for the buyer’s overseer. Then the maker needs to set up the task quality control plan dependent on this inspection and test plan.

The manufacturer tells the buyer’s inspector ahead of time to go to the industrial facility for seeing the inspections and tests. The correspondence and coordination channel between the manufacturer, buyer inspector and buyer are consented to in the Pre-inspection meeting (PIM).

Given the global practice, the maker sends a notice to the buyer, and the buyer audits the warning and sends it to the examiner. Then the monitor will go to the maker’s shop to observe the test or inspection. The buyer’s auditor will send the inspection visit report to the buyer. The Purchaser can dole out its inspector, its immediate representative, or hire a third-party inspector.

The ITP must be from a fair organisation and the substance extricated from the development code. In each column of the table, there is quality control and inspection necessity and this figures out which party is answerable for control and inspection.

There are three gatherings in the ITP, the Manufacturer, the Third Party Inspector (TPI) and the Client or buyer. Regularly, the table obliges three areas as follows: before manufacturing, during manufacturing, and last inspection. The first segment includes the Pre-Inspection Meeting (PIM), and the survey of the quality control archives. There are four significant phrasings in the ITP that decides the obligation of each party.

Hold Point (H): Hold on to the creation till TPI Inspector performs inspection and manages the necessary test. By and large, participation in the PIM meeting, unrefined substance inspection and ID, Post Weld Heat Treatment Review, Hydrostatic Test, Performance Test, Run-Out Test and Final Inspection are Hold focuses. Ordinarily, manufacturers will inform the TPI Inspector 7 working days ahead of time.

Witness Point (W): The maker will advise the customer and TPI Inspector, yet there is no hang on the creation. The customer can postpone this inspection dependent on its tact and illuminate the TPI Inspector.

Spot Witness (SW): For things with spot observers, the manufacturer will tell the TPI investigator comments while checking. For instance, one random visit for the UT Tests is enough for the entire surface readiness work for painting.

Audit (R): Review implies Review archive, which incorporates the survey of value control records, test reports, and so forth. When the TPI inspector visits a hold or witness point, the monitor can survey the connected reports.
