Grinding Down Welds How To and Should You Welding Mania

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.

Why hard turning can be an alternative to grinding for many

Hard turning typically refers to a lathe or turning center using singlepoint turning tools to process materials with hardness values over 45 HRc typically in the 5868 HRc range. With singlepoint cutting and turning the process can produce grooves and contours even high precision threading in a single chucking.
