Only some basic considerations for the designer in developing weldments are brought out in this paper, because of the wide scope of the subject. Separately, these basic considerations may seem elementary and self-evident, but when considered collectively in developing a weldment, their complexity becomes apparent. At least twelve different types of components can be utilized by a designer in his weldment and each of these components can be used in several ways. So, the designer must be familiar with limitations in processing weldments and with the scope and limitation of equipment and methods used in their production. These are the factors discussed here. However, this discussion is limited to dynamically loaded welded machinery parts.
