What is Camber in Welding?

Camber is the deviation from edge straightness, usually the greatest deviation of side edge from a straight line. It can occur during welding when the heat input is not uniform or when the weld bead is not deposited squarely on the previous layer. Camber can also be induced by thermal distortion after welding. When uncontrolled, camber can adversely affect joint fit-up, cosmetics, and fatigue resistance. Therefore, it is important to control camber during welding.

Camber is typically measured with a ruler or tape measure over the length of the weld. The amount of camber present is typically expressed as a percentage of the total length of the weld.

For example, if a weld has a length of 100 mm (4 inches) and the camber is measured to be 2 mm (0.08 inches), then the camber percentage would be 2%.

There are a few ways to control or minimize camber:

One way is to adjust the welding parameters such as welding speed, current, and electrode angle.
Another way is to use a jig or fixture to hold the workpiece in place so that the weld bead is deposited squarely on the previous layer.
Finally, post-weld heat treatment can be used to reduce thermal distortion and thus minimize camber.

What is camber in fabrication?

Camber is the deviation from edge straightness in a fabric or other flat material, usually the greatest deviation of one side edge from a straight line. It can occur during fabricating when the cutting or shaping is not done uniformly or when the fabric is not laid out squarely. Camber can also be induced by stretching or shrinking after fabrication.

Why is Cambering done?

Cambering is done to improve the appearance or function of a fabric. For example, cambering may be used to make a fabric lie flatter, hang straighter, or drape better. It can also be used to reduce wrinkles or create a decorative effect.

Camber beam

A camber beam is a type of beam with a curved upper surface. It is used in bridges and other structures where it is necessary to provide extra support without increasing the weight of the beam. The curvature of the beam allows it to distribute weight more evenly, which reduces the stress on the supporting structure.

What is pre camber?

Pre camber is the curvature that is built into a beam before it is installed. This curvature helps to distribute weight more evenly and reduces the stress on the supporting structure.
