What protects the molten SAW pool from the atmosphere?
The methodused for protecting molten SAW pool from the atmosphere.
Explanation of Solution
SAW stands for Submerged Arc Welding. It is a type of welding process which is used for thejoining of similar as well as dissimilar metals.In SAW, the arc is produced between the electrode and workpiece to be joined. The heat produced from this arc is used for the fusion of these metals.The fusion forms a molten pool. This molten pool is protected from the atmosphere by using a thick layer of flux or slag. The molten flux or slag is formed by the granular fluxing.
This slag covers the spark, radiation of arc and fumes which are produced duringthe welding process. It also prevents the molten metal to react with the contaminants of air, and hence gives a good quality of weld. Submerged Arc
Welding is used in horizontal welding position. It has a high penetrating power. This high power reduces the amount of filler metal used in the welding process. It has high amount of deposition rate. It possesses a better quality of weld.
