Techniques for Welding Pipe 90 Degrees

Welding pipe perpendicular is a critical skill that requires precise technique and attention to detail. If done correctly, it can help ensure the safety of any structure built with the pipe. In this blog post, we will discuss the steps necessary to ensure a precise weld when welding pipe perpendicular.

Understanding Your Angle

The first step in welding pipe perpendicular is to make sure your angle is correct. It’s important to measure before you begin welding, as an incorrect angle can affect the structural integrity of your project. To ensure accuracy, use a protractor or level to measure and double-check that your angle is exactly 90 degrees.

Welding Technique

Once you’ve checked your angle, it’s time to focus on technique. Before beginning, the weld, set your amperage low and practice on scrap metal until you have achieved accuracy and consistency in holding a steady arc length and consistent travel speed. The trick for achieving a perfect perpendicular weld is establishing a “V” shape at the joint edge before moving forward with full penetration. This ensures proper alignment of the two pieces being joined together while also providing greater strength once the weld has cooled and solidified into place.

Use Quality Equipment

Using quality equipment is especially important when welding pipe perpendicular, as any inconsistencies can cause problems during fabrication or installation. Make sure all of your equipment – such as clamps, wire feeders, grinders, and torches – are in good condition and up-to-date before beginning work on your project. It’s also important to check for any potential gas leaks which could cause safety risks or poor welds due to inconsistent gas flow rates.


Welding pipe perpendicular requires precision and attention to detail in order to be successful. From understanding your angles and practicing proper technique with quality equipment, following these steps can help ensure that you achieve a strong, safe weld every time you pick up your torch! Whether you’re working on a large industrial project or just doing some weekend DIY work around the house, welding pipe perpendicular correctly is essential for success!
