Figure 4.35 – Uninterrupted and interrupted welds

Some corner joints, T- joints and also lap joints are characterized by the size of leg K
(fig.4.36).
A leg weld is the shortest distance from one surface of welding parts to the border of a
corner weld and the surface of another weldable part.

a) b)
Figure 4.36 – A leg weld

The form of edge preparation depends on the thickness of welding parts, the position of a
weld in the space and other information. A bevel angle is an angle  between the bevel edges of
weldable parts (fig.4.37).

Figure 4.37– A bevel angle

The way of making a weld depends on the thickness of weldable parts and technical
conditions of welding. Welds are one-sided (fig.4.38, а) and two-sided (fig.4.38, b).

а) b)
Figure 4.38 – One-sided (a) and two-sided (b) welds

In the welds of the welded joints there are the obverse and reverse sides. The obverse side of
the weld is that from which welding is done (fig.4.39).
