What is the Bend Radius in Welding?

The radius of curvature on a bend specimen or bent area of a formed part is measured on the inside of the bend, and is an important factor when considering weldability. The smaller the radius, the more difficult it is to produce a sound weld. When welding metals with a low melting point, such as aluminum or magnesium, the use of a larger radius is often necessary to prevent the metal from becoming distorted during welding.

Why is bend radius important?

The bend radius is important because it helps to prevent the metal from becoming distorted during welding. A small radius can make it difficult to produce a sound weld, while a larger radius will help to prevent distortion.

How do I choose the right bend radius for my project?

Choosing the right bend radius for your project depends on several factors, including:

the type of metal you are welding,
the thickness of the metal,
and the amount of heat being used.

How do you determine bend radius? What is the bend radius ratio?

The bend radius can be determined by measuring the inside of the bend, from the center point to the outer edge.

The bend radius ratio is the ratio of the maximum to minimum bend radius.

What is the minimum bend radius?

The minimum bend radius is the smallest radius that can be used without causing distortion in the metal. How to calculate the minimum bend radius of sheet metal? The minimum bend radius of sheet metal can be calculated by dividing the thickness of the metal by the coefficient of friction.
