A similar situation arises in the case of manual versus automated welding. A number of different processes may be used to produce welds. Each has its benefits and drawbacks. Chapter 7 discusses welding in detail and provides a comparison of various welding processes, including deposition rates. Items to consider include equipment and setup costs versus the benefits of more efficient placement of welds, design for production runs rather than individual fabrications, and weld configurations, such as narrow welds to minimize weld metal required and residual stresses.
