Features to Look for in a Pipeline Welding Machine
Keep the varying thickness of pipelines in mind so you get a welder that produces enough power for a range of operations.
Whereas a welding machine with 120 to 140 amperes power can be considerable for domestic purposes, you will need 200A to 300A amperes power for more demanding projects. Pick a welding machine with a range of outputs.
While welding machines are mostly used outside, they require a dependable power source. Many pipeline welders come with an inbuilt generator to handle the machine’s operations for a long time.
It is the percentage of producing current in a given minute. For example, how much particular current a welding machine can produce within 10 minutes without overheating is called a duty circle.
A welding machine rated at 150A and with a duty cycle of 70% needs at least 3 minutes of rest after welding continuously for up to 7 minutes at 150A. Usually, a lower amperage welder offers a higher duty cycle. Thus, having 100A will let you enjoy an 85% duty cycle. Choose a welding machine that provides a large duty cycle for a certain power output you need for the task. Some professional-grade welding machines offer a 100% duty cycle for output.
The required welding technologies depend on the different thicknesses and materials of the pipelines. The most common techniques are Gas Tungsten Arc Welding (GTAW), Metal Inert Gas (MIG) welding, and TIG welding.
While MIG welding is better for thicker and larger pipes, TIG is ideal for thinner pipes and lighter projects. However, it is recommended to choose a welding machine that can handle any type of pipe welding project without considering pipe thickness and the scale of the project.
When it comes to a powerful device like a welding machine, it is vital to keep its safety features in mind. Surge protection is among the unavoidable safety features. Besides, the recommended safety level is between 20% and 25%.
Pipeline welding is a type of highly portable job which is related to lots of dragging and traveling with welding equipment. Thus, it is better to have an easy-to-move machine for any type of pipeline welding project. A portable welding machine should be convenient, lightweight, and should have the ability to withstand tough environments.
As a pipeline welder, the following safety tools should not be overlooked:
Obviously, the pipeline welding machine is the main tool for a welder. Despite the pipeline, the welder should have a couple of things to complete the task safely and properly. They are:
This gear is mostly used for oxyacetylene and autogenous welding. During the welding of the pipeline at extremely high temperatures, the generating plasma emits ultraviolet rays that are extremely harmful to the eyes.
A welding goggle effectively protects from such a situation and only leaves the light intensity required to see the work.
It’s another must-have gear for a pipeline welder. A welding mask not only protects the eyes, but also the entire area of the face. One can increase its effectiveness by using the sun. If the light is dark, the mask won’t offer better protection.
Gloves for the pipeline
The glove is yet another piece of protective equipment for the welder, as it protects against any hot slime. It also protects against the heat released by the electrode or the torch.
An apron greatly protects the welder’s body against splashes. Moreover, it includes front pockets that allow storage of some necessities required for the welding pipeline.
Other accessories you will require are:
• The Gas filter
• Metallic brush or card
• Welding tables
Some common mistakes that welders should avoid while pipeline welding:
• Many welders don’t prepare the weld surface, which leads to slag entrapment. Besides, due to the lack of fusion, a welder may have weaker welds and defects.
• If the welder doesn’t joint alignment properly on the weld surface, it can lead to a weaker structure and a poor-looking finish.
• The welder doesn’t get enough preparation for joining. Different welding processes necessitate a distinct joining method.
• Shielding gas is used by some welders because they believe it is better for welding, but it should be avoided.
For home use, a welder with a power range of 120 to 140 amps is adequate. But if you need to weld continuously for larger projects like pipeline use, then you should get a welder with at least 180 amps.
Compared to other practical jobs, welding offers a healthier and more stable career. A pipeline welder can earn between $36 and $52 per hour in arms pay, $15 to $25 per hour in truck pay, and between $100 and $150 per diem.
Some of the highest paying welding jobs are:
• Pipe welder: $24.50 per hour
• Structural welder: $20.55 per hour
• Welder/fitter: $19.25 per hour
• Welder: $17.90 per hour
• Fabricator/welder: $17.76 per hour
• MIG welder: $16.24 per hour
• Welder helper: $13.53 per hour
The risk and demand related to pipeline welding make it only workable for licensed welders. Undoubtedly, pipeline welding is the highest-paying gig among the different types of welding jobs. As a result, the welder needed to get the best pipeline welding machine with a lot of power to tackle the challenge, which was not a cost-effective investment. Fortunately, you now have some of the best places to find the right welding machine for the pipeline.
Most importantly, the welding machines we reviewed above are priced differently due to their different specifications, but they are all the best in their class. However, if you are a professional welder or contractor, do not compromise the quality of the welding machine due to cost, as quality welding machines are an investment that will last a lifetime.
