There are several different ways to join metal parts together to make different products. This includes welding, seals, soldering, and a range of fittings and fixtures. Whatever the choice, it is important to ensure the joints are strong and reliable. Visual inspection or VT can be helpful to check them for signs of problems. It can complement other methods of non-destructive testing (NDT).
Issues to look for
The problem with joining metals is each method of creating a joint can have flaws. For example a weld may be shallow, uneven, or have discontinuities. Seals can have problems such as gaps and poor adhesion. Soldering can have similar problems to welding. Any fixtures or fittings may also be poorly fitted or have flaws.
The main consequence of flaws in joints is the final product may not be as strong as you expect. This could even lead to accidental structural failure in some situations. That is to be avoided at all costs as it could be a serious risk to health and safety.
Another concern is leaks. Metal tubes can carry all kinds of substances, including water, different gases, oil, and more. These are often pressurised to transport the resources. However, a flaw at a joint could allow a leak. This could result in the release of harmful substance, a loss of resources, and even put people and the environment at risk. The same issue can occur with joints on storage containers and pressure vessels.
Start off with visual inspection
Every business should make visual inspection the first step of their quality checks and maintenance schedule. While it can only provide a basic surface check, it can discover obvious flaws like cracks and gaps in joints. It is a great starting point before moving on to other more intensive tests like UT, magnetic particle, or dye penetration.
Format NDT Ltd appreciates the importance of checking joints for flaws. We can offer clients a full range of professional services, including VT and more. With our help they can get a clear idea of the condition of each joint, whether it is a weld, a seal, or solder. Our techniques are non-destructive, plus we can choose different ones to look at the surface and inside of the joint.
