What is a Hot Pass in Welding?

In welding, the hot pass is the second pass that goes over the root pass. This weld pass helps to ensure that the root pass is properly fused and provides additional strength to the overall weld. The hot pass also helps to prevent any defects from forming in the final weld.

To perform a hot pass, the welder will first need to clean the area around the root pass. This will ensure that there is no debris or other contamination that could cause problems with the weld. Next, the welder will need to preheat the metal in the area to be welded. This helps to prevent the metal from cooling too quickly and cracking.

Once the metal is preheated, the welder will then begin to weld the hot pass. The welder will need to use a higher heat setting than they did for the root pass in order to ensure that the metal is properly fused. After the hot pass is complete, the welder will then need to cool the area down slowly in order to prevent any cracking.
