When are the slag pans removed after the weld has completed pouring?

The correct timing for removing the slag pans after the weld has completed pouring is three minutes. This timeframe is critical because it allows the weld metal to begin solidifying sufficiently, reducing the risk of damage to the weld while still allowing for proper removal of the slag pans.

Removing the slag pans too early may result in disturbance to the weld or the molten metal, which can affect the quality and integrity of the weld joint. Conversely, waiting too long can lead to difficulties in removing the pans due to solidification and cooling, making the process labor-intensive and potentially impacting the finish and alignment of the welded components.

By adhering to the three-minute guideline, welders ensure that they strike a balance between optimal slag removal and maintaining the quality of the weld, which is crucial for the structural integrity of the joint being created.
