What is the maximum wind speed permitted while welding using GMAW or FCAW-S?

The maximum wind speed permitted while welding using Gas Metal Arc Welding (GMAW) or Flux-Cored Arc Welding with Shielding (FCAW-S) is critically important for ensuring the integrity of the weld. Wind can disrupt the shielding gas used in these welding processes, which is necessary to protect the molten weld pool from atmospheric contamination. If the wind speed exceeds the permitted limit, it can lead to inadequate shielding, resulting in defects such as porosity or lack of fusion in the weld.

A wind speed of 5 miles per hour is the recognized maximum limit for these welding processes. This allows for a stable environment where the shielding gas can adequately protect the molten weld from the elements. Keeping the wind speed at or below this limit helps ensure high-quality welds and enhances the safety of the welding operation.
