What is a Bevel Angle in Welding?
The bevel angle is the angle formed between the cut surface and a theoretical plane perpendicular to the plate surface. Plasma arc cutting tends to remove more metal from the top than from the bottom, producing a bevel angle on the weld. (Also referred to as cut angle).
When welding two pieces of metal together, it is important to choose the right bevel angle to ensure a strong weld joint. Too shallow of a bevel angle can result in a weak weld, while too steep of a bevel angle can make it difficult to fill the weld joint properly.
The most common bevel angles used in welding are:
 30 degrees,
 45 degrees,
 and 60 degrees.
How do you determine the bevel angle of a welder?
Different types of welding require different bevel angles. For example, when welding two pieces of metal together with a lap joint, a 45degree bevel angle is typically used. This provides good weld penetration and allows the weld to be easily filled. When welding two pieces of metal together with a butt joint, a 60degree bevel angle is typically used. This provides good weld penetration and strength while also allowing for a smaller weld bead.
What is a bevel weld used for?
A bevel weld is used to join two pieces of metal together at an angle. This type of weld is often used in the construction of buildings and bridges, where two pieces of metal must be joined together at a slanted angle.
Why is a bevel needed before welding?
A bevel is needed before welding to prepare the edge of the metal for welding. The bevel creates a surface that is perpendicular to the plate surface, which allows for proper weld penetration.
How do you calculate bevel angle?
To calculate the bevel angle, you will need to know the thickness of the material being cut and the width of the kerf (the width of the plasma arc). The bevel angle formula:
Bevel Angle = Arc Width / Material Thickness
For example, if the width of the kerf is 0.5 inches and the material thickness is 1 inch, the bevel angle would be:
Bevel Angle = 0.5 / 1
Bevel Angle = 0.5 or 30 degrees.
How to bevel pipe for welding?
Pipes can be beveled for welding using a variety of methods, including grinding, milling, and plasma cutting.
