When it comes to any kind of pipe assembly or tank construction, one of the best ways to get the job done is with a girth welder. Girth welders are a great option for ensuring a quick and easy weld around the diameter of a pipe or tank. Before you make a decision on your fastening investments, here's what you should know about girth welding.

How Does Girth Welding Work?

Girth welding is a welding process that's done in a few different passes. The welder will rotate around the tank or pipe to ensure a consistent, solid weld. The first rotation will be the slowest one. This initial pass creates the foundation of the weld. It's the most challenging part of the entire process and must be done at a tightly controlled speed for the right results.

The second rotation is designed to fill out the weld. After this pass, the weld is thicker, denser, and more solid. It's usually a fairly quick pass and is done at a consistent speed. The third rotation is the final one, and this rotation is the one where the weld is completed and capped off with a smooth surface finish.

What Are Your Options For Girth Welding?

There are several different approaches for girth welding. You'll need to choose the approach that's right for you based on your situation. For example, you'll need to think about manual welding, semi-auto welding, and automatic welding. While manual welding is done entirely by hand, automatic welding is an automated process that will work for you without much manual intervention.

How Do You Choose The Weld Type?

There are several things you'll need to consider when you're choosing the weld approach. For example, the base metals will play a role in determining which weld type is the most effective. You'll want to be sure that you choose a girth welding method that's going to work well with the material that the pipe or tank is crafted from. That way, you get a solid, consistent weld.

In addition, you'll need to think about where the pipe or tank will be installed and consider any exterior pressure on it that may affect the integrity of the weld. You'll need a stronger, more reliable weld for an application that's experiencing a lot of external pressure than you would for a fixture that's not under any strain.
