Joint methods

A sound welded joint requires proper joint preparation both before and during the welding process. Accurately preparing the joint will also help to prevent various types of welding defects.

Joint types

Welding joints can be divided into two categories:

Joint geometries

The joint geometry explains the shape, dimensions, and configuration of the parts to be joined together, including how the edges of the material is prepared before welding.

The size of the joint root gap

The width of the root gap affects the penetration of the first weld pass.

Other joint preparations

Keep the joint preparation area clean from contaminants such as moisture, grease, rust and oil prior to each weld pass.
