Final answer:
Comparing the weld to a drawing verifies compliance with specified dimensions and tolerances and is crucial for quality control, not just aesthetics or technique.
Step-by-step explanation:
Comparing the weld produced or the fit-up to a drawing is an essential step in the welding process. This comparison verifies compliance with specified dimensions and tolerances, which is crucial for ensuring that the structural integrity and function of the welded component meet design requirements. It is not about making the weld visually appealing, optional in quality control, or focusing on the welder's personal technique.
