Selection of Welding Joints - The selection of a suitable joint for a particular type of weldment depends upon the following factors;
(a) Base plate thickness.
(b) Geometry of structure.
(c) Magnitude of locating.
(d) Type of loading, i.e., tension, shear, impact, bending, etc.
(e) Rate of loading (sudden or gradually applied).
The load or stress applied on a weldment may be static or dynamic. A static load places the least strain on a weld. The most severe load is stress under dynamic or changing conditions.
(f) Cost of joint (edge) preparation and amount of filler metal used.
