Mistakes in pipe fabrication processes could lead to costly project delays. That’s why partnering with high-quality metal fabrication companies is so critical.
Pipe welding or fabrication is a simple yet extremely nuanced process. Although the ultimate goal of this technique is to join two or more pipes, there are many ways to achieve this objective. Pipe fabrication is achievable through different fabrication and welding techniques like TIG welding, MIG welding, arc welding, etc.
To carry out any of these techniques, workers need to be extremely skilled and minimise the margin for error. Without precision, there’s always room for weld defects. The last thing providers of pipe fabrication in Sydney need is for their clients to be forced to recall some of their products.
Here are the risks that come with partnering with inexperienced pipe fabrication experts and how they can be avoided -
Not Preparing the Pipes
There aren’t many pipe fabrication processes that don’t require the pipes to be prepared before welding. From ensuring that the edges of the pipes that need to be fabricated are smooth (surface grinding) to cleaning the pipes to eliminate all lubricants – good fabricators always follow intensive pipe preparation practices.
Not preparing the pipes for the fabrication process can lead to many complications. The pipes may refuse to fuse or have weak welds in between them. Hydrogen atoms may get included in the welds leading to slag entrapments. Working with pipe fabrication companies that prioritise preparation processes is the only way to avoid this risk.
Misaligned Parts
When parts of the pipe aren’t aligned properly while being joined, various alignments of the surfaces arise. Customers can’t expect the filler material to automatically adjust to these alignments on the surfaces. When fabricators rush the welding process, they create misalignments which lead to unnecessary welding defects.
To avoid the risk of creating structurally weak welds, customers must partner with experts of pipe fabrication in Sydney who have track records of delivering high-quality results with little to no misalignment-related issues. These experts use the correct speed, voltages, and angles to restrict misaligned parts to minimal levels.
Avoiding WPS Guidelines
Welding Procedure Specifications (WPS) are documents containing important information for the fabricators and the welders. The information presented in these documents helps them create pipe fabrications that are consistent with the code requirements. A typical WPS document for pipe fabrication in Sydney will feature -
- Details about which fabrication and weld types need to be used.
- Information about suitable welding and fabrication positions.
- Clarifying what filler materials need to be used during the pipe fabrication processes.
- Details about preheating and post-heat temperatures.
- Guidelines on weld and fabrication treatment processes.
Experts of pipe fabrication in Sydney use WPS documents to obtain all information that relevant to the fabrication process. On the other hand, inexperienced metal fabrication experts avoid referring to the WPS before starting their welding and fabrication processes. Ignoring such documentation comes with various risks.
A standard process of pipe fabrication in Sydney will have many variables. From the properties of the pipe materials to the need to use tools like flow regulators – a lot of important details are clarified in WPS documents. That’s why companies must only work with pipe fabrication experts who adhere to these vital documents during projects.
