Quality control is a vital component in metal fabrication. It ensures your product meets certain standards and specifications and performs as designed. That is why having a well-defined Inspection and Test Plan (ITP) is critical to the fabrication process. It provides the checks and balances that determine if your work methods will result in a compliant end product. It may also enable effective communication and collaboration between all parties involved and assist in establishing expectations and desired outcomes.
Having an ITP to help structure and standardise your quality control procedures can play a significant role in the success of your output. And this is how:
What is an ITP?
An ITP, or Inspection and Test Plan, details the step by step procedural requirements of testing and inspection during the fabrication process. This “what, how, why, when, and who” plan outlines the critical stages in the process where scheduled inspections and verifications should occur to ensure that operation and safety parameters are being met. For example, an ITP will summarise the following:
- What are the requirements?
- What tests/inspection methods will be carried out to assure compliance?
- How will compliance be demonstrated?
- Who will witness and verify the compliance?
- When are inspections and testing required to be completed?
- Who is responsible for undertaking the inspections and testing?
The purpose of the ITP is to determine any need for corrective action at these pre-defined junctures and enable responsible parties to review and authorise each stage before the process moves forward.
Why do you need an ITP?
The ITP is fundamentally your safeguard against errors. An effective ITP describes the intended plan for managing the quality control and assurance of metal fabrication and provides an opportunity to explore, identify, and strategise in the following areas:
- Risk assessment: understanding what could go wrong and determining ways in which to avoid mistakes, omissions, and defects.
- Fault detection: developing a testing and inspection method that can detect and rectify errors in a timely manner.
- Accountability: defining who is responsible for what and at what stage of the process.
In mapping out a structured path, the ITP offers documentary evidence to verify that the correct procedure has been observed and compliance requirements met. It also ensures accountability at every stage of the process by acting as a record of what work has been done, what has been inspected, when these inspections occurred, and who conducted and authorised each quality check.
How does an ITP improve quality?
Implementing and adhering to a comprehensive ITP provides the assurance that your product is of the highest quality and is built to purpose. Because work is regularly checked for compliance with quality management standards during the fabrication process, the end product will be markedly better than if an ITP was not used.
