Welding classes
The welding classes are given in5817 If the designer has specified a welding class on a drawing, this has been done in order to ensure that the production unit is aware of the quality requirements applicable to the joint ISO 5817 specifies three different
quality levels: B, C and D, with Class B being the strictest. The standard includes tables that specify different types of defects,
and how large they are permitted to be in the various quality levels.
Class D is usually used for non-load-carrying parts or in structures subjected to only
low static loads.
Parts subjected to high static loads are normally welded according to Class C.
Parts subjected to fatigue loading are normally welded in Class C or Class B, with
the additional requirement that the transition between the weld and the workpiece mate-
rials must be smooth. In extreme cases of fatigue loading, there may be a requirement that the edges of the weld must be ground or TIG-treated to produce a rounded shape
