using statistical and numerical approaches – A reference guide Abstract Welding input parameters play a very significant role in determining the quality of a weld joint. The joint quality can be defined in terms of properties such as weld-bead geometry‚ mechanical properties‚ and distortion. Generally‚ all welding processes are used with the aim of obtaining a welded joint with the desired weld-bead parameters‚ excellent mechanical properties with minimum distortion. Nowadays‚ application of design
