During which temperature range should finish grinding of the weld be performed?

Finish grinding of the weld should be performed within the temperature range of 900 to 600 degrees. This range is critical because it allows for the effective finishing of the weld while the material is still within an appropriate thermal state.

During this temperature range, the weld metal is solidified but not completely cooled, which makes it easier to grind and shape the weld without causing damage or introducing stress concentrations. Grinding at too high a temperature can lead to excessive wear on grinding equipment, while grinding at too low a temperature may cause the metal to harden and become more difficult to grind, potentially leading to cracks or other structural issues.

Selecting the optimal temperature range ensures that the mechanical properties of the weld are maintained and that the final weld surface meets the required specifications for strength and integrity.
