Figure 4.42 – The example of T-Joint (a) and interrupted lap welded joint(b)

The example of T-Joint T1 is shown in fig.4.42 (a). It is weld without bevel edge, two-sided,
with length of a leg weld 5 mm.
The example of an interrupted lap welded joint H6 is shown in fig.4.42 (b). Width of a weld
is 6 mm, length of a weld is 50 mm., pitch of a joint is 100 mm.

4.6.2 SOLDERED AND GLUED JOINTS
A conventional views and drawings of soldered and glued joints are in State Standard 2.313-
82.
The place of joints of parts must be represented by a continuous line 2S thick.
For drawing of the soldered and glued joints conditional marks are used which put on lines –
leader by a continuous mainline: C- for a soldering, - for glued joints. The soldered joint is shown
in fig. 4.43 (a), glued joint – in fig. 4.43 (b).

Figure 4.43 – Drawing of the soldered (a) and glued (b) joints
Joints, executed on the closed line, must be marked by a circle with diameter from 3 to 5
mm, drawing a thin line (fig.4.44). The sizes of joints and denotation of roughness of the surface
should be pointed out on drawing of a soldered joint in case of necessity.
