Pipe welding is one of the primary methods used to combine multiple pipes. Some of the top welding techniques include TIG welding and MIG welding. Some make a distinction between pipeline welding and pipe welding. Pipe welding relates to the metal pipes that are at plants and refineries. Pipeline welding refers to the pipes used to transport water, gas, and oil. A pipe welding company like ours can work across numerous sectors, including assisting nuclear power stations, fabrication shops, and water industries.

Welding Processes We Use
Pipeline welding is usually done by using the below methods. Our company is experienced in a huge range of different pipe welding techniques, so you know you can trust us to ensure that the best technique is adopted for the job. Want to find out more? Take a look below.
Shielded metal arc welding, or SMAW, is also known as stovetop welding. When we utilize this technique, it means that there is no flux and no shielding gas required, either. This makes it easier than ever for us to port our welding equipment. The metal is welded to the corresponding piece by simply melting the electrodes. This is done through heat via the electric arc. Even though SMAW has many advantages, the slow speed could be more productive compared to other techniques.
Gas metal arc welding offers a much higher level of productivity when compared to SMAW. It can be done with automatic or semi-automatic equipment, and the deposition rates are very high. These techniques require much better control of the welding variables, but the result is both high in quality and efficiency.
FCAW stands for flux-cored arc welding. Gas-shielded welding like this uses semi-automatic machines, giving you a superior welding solution for a range of pipes. One thing to note is that windy conditions can disturb the shielding gas, which can lead to many porosity defects. FCAC, which is self-shielding, avoids this by not using a shielding gas.
ARC Welding (Submerged)
Submerged arc welding is usually done via a semi-automatic process. The arc is not visible, making it very difficult to trace. That being said, it has the highest deposition rate and can also deliver a surface free from any defects.
Tungsten Inert Gas welding is also known as GTAW. The deposition rate is low, and it has higher equipment costs. That being said, the weld quality is high, making it the best option for high-precision jobs.
Advantages of Welding
If you opt to have your pipes welded, you should know that this will come with several advantages. This is especially the case when you compare it to screw fittings.
Welding is ideal as it helps to eliminate the need for fittings. A screwed pipe requires a fitting with every joint, but if you opt for welding, this can join pipes together, and it can also end preparation for the parts that must be joined.
Welded pipes can adopt a thinner wall pipe compared to a screw connection. This leads to a much lower cost overall. Screwing pipes requires a very high cost of labor, as you have to have a lot of technical expertise, and you also need to pay out for the fittings themselves.
Screwed fittings are known for generating a lot of turbulence, not to mention that they have a high level of fluid resistance through the pipes. Welded solutions are ideal as they give you a streamlined surface and facilitate an improved flow overall.
Ease of Repair
If you opt for a welded system, this tends to be much easier to repair when compared to a screwed system. A welded pipe can often be repaired in place, but if you opt for a screwed system, then this can require a great deal of disassembly when it comes to repairing. This will increase labor costs as well as downtime.
Insulating welded pipes is straightforward, as you do not have any threaded connections when it comes to difficult bumps. This makes for much easier insulation overall.
Cons of Opting for Welding
There are some cons of welding, but that being said, all of this can be avoided if you take the time to ensure that you are going through a reputable company, such as ours. The best way to prevent some of the most common mistakes with pipe welding is to have a solid understanding of the process and to know the conditions you are working with. Our team has a great deal of knowledge regarding things like this, so you can trust us always to ensure a positive result.
Pipes need to be Prepared
Before you even think about welding the pipes together, you have to make sure that you prepare them. You have to ensure that the edges are joined and that they are both clean and straight. If you do not do this properly, you may experience a lot of issues, including a lack of fusion, slag traps, and even hydrogen inclusion. When you come to us, you won’t have to worry about this as we prepare every surface and ensure that the job is done to the highest standard.
Aside from the general preparation, it is essential to know that various challenges are associated with working conditions. You have a risk of injury if the proper precautions are not taken.
Another risk of welding would be working in various bad conditions. Luckily our team is highly trained, so this is a con that can be eliminated.
