Describe a root weld.

What will be an ideal response?


A root weld is the first weld in a joint. It is part of a series of welds that make up a multiple pass weld. The root weld is used to establish the contour and depth of penetration. The most important part of a root weld is the internal root face, or, in the case of pipe, the inside surface. The face, or outside shape, or contour of the root weld is not so important.
