Why must the weld crater be cleaned before starting a new electrode?
The reason of cleaning the weld crater before starting a new electrode.
The main reason of cleaning the weld crater before starting a new electrode is to prevent the weld crater to slag incursion.
A 'crater' is a small explosion which will allow the droplets of molten metal to flow in every direction. It is the result of encountering small pockets of oxidation inside or on the surface of the metal being welded.
The reasons of cleaning the weld crater before starting a new electrode are as following:
- To prevent the weld crater to slag incursion...
