There are many types of welding. A well thought out welding procedure goes a long way towards efficient fabrication of high quality weldments. A welding procedure must ensure the necessary strength of the resultant welds, lowest possible stresses and strains and the lowest cost of manufacture.

DETERMINING THE WELDING PROCESS 

There are many types of welding. Determining which process is most appropriate itself involves a huge task.

Primarily, the joint to be welded is analyzed in terms of its requirements. Whether weld joint is large or small, or the joint is out-of-position or not, and whether the base metal is thick or thin. Further discussion on determining the process of welding can be found here.

Here is a list and description of the types of welding. Details of each can be found by clicking on the term.
