Compared to pipeline welding, conventional metal welding is a child’s play. For starters, pipes are of varying thicknesses. Moreover, pipes tend to be thicker than conventional welding materials. There is also the issue of the welding environment.
As a pipeline welder, you are effectively a welding nomad. You never know where the job may take you, from the deserts of Arizona to the Alaskan cold. On the plus side, pipeline welding gigs attract a handsome paycheck.
Due to pipeline welding being challenging and demanding, not every welding machine is suited for this. To get started on pipeline welding you will need the best welder For Pipeline. Ideally, you will require a welder that is more powerful than your ordinary welder.
Here are seven welding machines the offer power in plenty. Apart from being powerful, though these seven can also be used outside.

What is pipe welding
Pipelines are to modern cities what veins are to your body. Pipes are used the world over to transport all kinds of things from water, oil, gas and much more. Like most other man-made things pipelines are vulnerable to damage.
Furthermore, the installation of pipes typically involves joining sections of pipes. And here is where pipe welding becomes essential. Pipe welding is the art of fusing two pipe sections using a welding machine.
While there are other ways of joining sections of pipes, welding is the easiest. It removes the need for special threading tools. Also, welding is cheaper and offers fewer flow restrictions.
How to Select the Best Pipeline Welder
Pipeline welding is recognized as a specialized profession. Therefore anyone looking to venture into this industry will need to acquire a pipe welder. Not every welding machine out there can earn the title of the Best welder For Pipeline.
When shopping for the best pipeline welding machine, there are several things you need to keep in mind.
Pipeline welding is unpredictable due to pipelines having varying thicknesses. As such, you will need a machine powerful enough for different tasks. A welder’s power is based on amps output. For domestic use and amps output of 120 to 140 amps will suffice.
However, for welding pipes, a higher amps output is needed. Ideally, go for machines that have an amp’s output of 180 amps and over.
Pipeline welders are nomads who move from Jobsite to Jobsite. However, the machines used are usually powerful, large and bulky. To counter this, it is wise to get a welding machine that is easy to carry either in a truck or has a cart.
Pipes are made from different metals. Thus, a MIG, stick or TIG only welder will not do. For professional pipeline welding, you will need a machine that can do it all. This is to ensure you are not restricted regarding the type of metals you can weld.
The power source is another thing that you cannot be sure of. The power source you have at your disposal will depend on the job site. However, most industrial job sites usually have a 230v or 240-volt power outlet.
Nonetheless, you can never be too sure. A welder than can use both a 110v and 230 v power source will be an ideal option. This way you can plug it in almost any power outlet.
Common mistakes to avoid in pipe welding
- Not preparing the weld surface which can lead to slag entrapment, lack of fusion which results in weaker welds and defects
- Misalignment of the weld surfaces where the pipes aren’t joint in the right alignment leading to a structurally weaker and poor looking weld finish
- Poor joint preparation especially in line with the welding process being used, since different welding processes have different joint preparation procedures
- Using too much shielding gas in the hopes of creating better welds.
Tools you need
To get started as a pipeline welder you will obviously need a pipeline welding machine. But that’s not the only thing you will need to get. There are a couple of things other than the welder that you need to have before embarking on a pipeline welding project. These are.
A welding mask
As you probably have already noticed pipeline welding machines have a higher heat output than your average home welder. As such, you need something to protect your face from flying sparks and the intense heat.
A welding mask will help protect your face and in particular eyes. The intense heat can damage your eyes, especially when welding in an overhead position. Thus, a welding mask is another tool you will need.
Your eyes aren’t the only body part that needs protection from the intense heat produced when welding pipes. Your hands also need protection, especially since they are in close proximity to the welding torch.
Heavy-duty welding gloves will protect your hands from intense heat as well as any hot splash from the weld pool. Again gloves are particularly important when welding in an overhead position.
Metallic brushes are used to clean a metal surface before welding commences. Cleaning is essential for removing rust, dirt and trapped air. These things can result in a structurally and unpleasing weld.
While it is not always necessary, cleaning a metal surface before welding is always recommended. Thus, you may need a metal brush to clean the pipe surfaces before welding.
A pair of welding goggles
Welding goggles have a special tint that protects our eyes from the extreme heat produced when welding. Given the high temperatures produced when pipeline welding having a pair of welding glasses will be helpful.
