The 3 Stages of Weld Inspection

Proper inspection is crucial throughout the welding process, which means it has to be employed for all three stages—before the weld, during the weld and after the weld. This approach helps to ensure that correct welding techniques are being followed in each step, which is crucial for obtaining a weld inspection certification in the UK. Below we have mentioned how it is carried out for each step:

1. Pre-Weld Inspection

Weld inspection begins with pre-weld inspections that occur before any welding begins. This process involves verifying that all safety protocols are in place, reviewing relevant documentation such as welding procedure specifications (WPS) and ensuring that all necessary materials and tools are prepared. A pre-weld inspection helps to identify potential issues early on, thus, results in a successful welding operation.

2. During-Weld Inspection

During-weld inspection involves monitoring the welding process itself. In this phase heat input is tracked, cleanliness between weld passes is maintained, welding techniques are observed and joint positioning is evaluated to maintain quality. It is one of the most crucial steps in weld inspection. Here the welding process is actively inspected to detect and address problems as they arise to reduce the risk of defects in the finished product.

3. After-Weld Inspection

After-weld inspection is conducted once the weld has cooled and solidified. This step involves checking the weld size, identifying discontinuities or flaws and checking the strength of the weld through various means as well as ensuring that the weld meets all specifications. After-weld inspection is necessary for ensuring the quality of the final product.

Once these inspections are completed without any error, a weld inspection certification is issued.

Types of Weld Inspection

Weld inspections can be categorised into two main types: destructive and non-destructive. Let us take a look at what these two inspection types are along with the methods involved.

Destructive Weld Inspections

Destructive weld inspection (DT) involves evaluating welded joints by intentionally damaging or breaking them to assess their integrity and mechanical properties. This method is essential in critical applications where understanding a weld’s characteristics is paramount for safety and reliability. While effective for detailed assessments, destructive testing can lead to material waste and increased costs due to the destruction of test specimens.

Common Methods of Destructive Weld Inspection:

1.     Macro Etch Test: This type of destructive testing involves taking small samples from the weld and subjecting them to an acid etch to reveal internal structures.

2.     Fillet Weld Break Test: In fillet weld break, a sample is broken to examine its entire length for defects such as lack of fusion.

3.     Transverse Tension Test: Here samples are pulled until failure to determine tensile strength.

4.     Guided Bend Test: In guided bend test, samples are bent around a specified radius to evaluate ductility and identify flaws.

Non-Destructive Weld Inspections

Non-destructive weld inspection (NDT) encompasses various techniques that evaluate the quality and integrity of welded joints without employing any destructive procedure. This approach is vital across numerous industries—including aerospace, automotive, oil and gas—where maintaining operational reliability is crucial. NDT allows for thorough evaluations while preserving the integrity of components.

Common NDT Methods:

Visual Inspection (VT): This is the simplest form of NDT where welds are visually examined for surface defects.

Liquid Penetrant Testing (PT): Liquid penetrant testing or dye penetrant testing uses a liquid dye to reveal surface cracks.

Magnetic Particle Testing (MT): In magnetic particle testing a magnetic field is applied to detect surface defects in ferromagnetic materials.

Ultrasonic Testing (UT): This non-destructive testing technique employs high-frequency sound waves to detect internal flaws.

Radiographic Testing (RT): In radiographic testing X-rays or gamma rays are used to produce images revealing internal structures.

Eddy Current Testing (ECT): This NDT method uses electromagnetic induction to identify surface flaws in conductive materials.

Now that we know the types of weld testing, let us take a look at what makes non-destructive weld inspection a preferred choice over destructive welding inspection.

What Makes Non-Destructive Weld Inspection Better than Destructive Weld Inspection

Using non-destructive testing for obtaining weld inspection certification offers several advantages over destructive methods, for example:

Preservation of Assets

One of the most significant advantages of NDT is its ability to preserve the inspected components. Unlike destructive testing, which damages or destroys test specimens, using NDT ensures that materials remain intact and functional after inspection. This preservation is particularly crucial for high-value items, such as aircraft parts or critical infrastructure, where operational continuity is vital.

Cost-Effectiveness

NDT proves to be more cost-effective method for obtaining weld inspection certification. Since it eliminates the need for replacing or repairing the damaged specimens, companies can save significantly on material costs. NDT also allows for early detection of defects, which helps to prevent more serious issues from developing. This saves companies significant amount of money by avoiding downtime and repairs.

Increased Safety

NDT methods ensure enhanced safety as they do not expose materials to potentially destructive forces. This is particularly important for high-stress components where failure could result in catastrophic consequences. By identifying potential issues before they escalate, NDT contributes to a safer working environment and reduces the risk of accidents.

Time Efficiency

NDT methods are typically faster than destructive testing methods, which can expedite the process time for weld inspection certification. Many NDT techniques can be performed on-site and in real-time, allowing for immediate decision-making and reducing operational downtime. This efficiency is especially beneficial in industries with tight production schedules.

Non-Invasiveness

NDT techniques are non-invasive, which means they do not alter the physical properties of the material being tested. This characteristic is crucial for assessing the structural integrity of critical components, as even minor alterations can affect performance. NDT’s ability to conduct inspections without dismantling equipment ensures that operations can continue smoothly.

Continuous Monitoring

NDT allows for ongoing monitoring and routine inspections, enabling early detection of defects or damage throughout the lifecycle of equipment and structures. This proactive approach can prevent unexpected failures and enhance reliability.
