Welding is one of the common methods of joining metals, but the welding process is often accompanied by inevitable deformation. This article systematically discusses the different types of welding deformation, including linear deformation, angular deformation and shape deformation, and analyzes the main influencing factors causing these deformations, such as welding temperature, residual stress, welding method, etc. An in-depth understanding of welding deformation and its influencing factors will help optimize the welding process and improve the quality and accuracy of welded joints.

linear deformation

Linear deformation is one of the most common deformations during welding and includes elongation and contraction. When welding, the weld area is heated and expands, then shrinks as it cools. This deformation usually manifests itself as stretching or shortening of the welded joint.

Angle deformation

Angle deformation refers to the rotation or bending of the welded joint caused by the welding process. This deformation is often caused by uneven heating or residual stress, and is especially important for parts that require a perfect fit.

Shape deformation

Shape deformation is the change in the overall shape of the part during the welding process. It may include twisting, warping or bending. This deformation is often related to uneven heating or residual stress distribution.
