    Welding Procedures (overview) The cost impact of not being able to control the quality of welding and repair rates can be substantial. This will and can cost Grinding Down Welds: How To and Should You? ,While grinding your welds, you end up removing some of the thickness from the weld and the base metal. Grinding welds does inherently does lead to a reduction in the strength of the weld, as you are removing some amount of material from the weld itself. The degree of weakening depends on the amount of material that is removed.
