Joining Processes and Equipment

 JOINING INVOLVES MANY PROCESSES USED TO COMBINE INDIVIDUAL PARTS INTO A LARGER, MORE COMPLEX COMPONENT OR ASSEMBLY. The joints are where the individual elements of a component come together. Joints transmit or distribute forces generated during service from one component to another. The most common types of joints used in part joining are butt, tee, corner, lap, and edge joints.

The choice of an acceptable design for joining parts is based on a number of factors relating to both the product and the joining method. Aesthetics, manufacturability, repairability, dependability, inspectability, safety, and fabrication unit cost.

Because of the importance of assembly as a design constraint, there has been a significant increase in the attention on assembly in the design process. Design and manufacturing practise currently emphasises on ensuring that parts comply to specifications, minimising variability and randomness, and making non-value-added tasks like orienting and handling as simple and straightforward to do as possible. Many product design departments are now utilising design for assembly (DFA) strategies to increase the ease with which goods are constructed. DFA techniques strive to assure ease of assembly by generating designs that are straightforward to assemble.
