New Mexico Pipe Fitter Journeyman (JPF) Practice Exam

What is the usual pipe end bevel for fit up?

1. 30 degrees

2. 45 degrees

3. 37-1/2 degrees

4. 60 degrees

The correct answer is: 37-1/2 degrees

The usual pipe end bevel for fit up is 37-1/2 degrees. This angle is commonly used in pipe welding to create a proper groove that allows for good penetration during the welding process. The specific bevel angle ensures that there is sufficient space for the welding material to fill the joint adequately, providing a strong and reliable connection between the pipe ends. The 37-1/2 degree bevel is particularly advantageous as it strikes a balance between ease of fitting the pipes together and ensuring the welded joint has enough depth to achieve structural integrity. A bevel that is too shallow may not provide enough area for welding, while a bevel that is too steep could complicate the fitting process and make achieving a proper weld more challenging. Using the correct bevel angle is essential for ensuring the quality and strength of the weld, which is a critical factor in applications where the pipes will carry fluids under pressure or where structural support is necessary.
