How the Submerged Arc Welding Process Works. Submerged arc welding gets its name from the process itself. The welding process is invisible to the eye as it happens under a thick layer of flux – the flux is conductive when molten, allowing the current to pass to the workpiece without any sparks, splashing or fumes.
Mechanics of the Welding Process. In submerged arc welding, a powerful arc melts metal surfaces together. It creates a smooth, even weld pool quickly. This method is known for its high productivity and superb weld quality. It also reduces spatter and defects. Advantages and Limitations of SAW. SAW has several benefits: Creates high …

A shielding gas is not required. Prior to welding, a thin layer of flux powder is placed on the workpiece surface. The arc moves along the joint line and as it does so, excess flux is recycled via a hopper. Remaining fused slag layers can be easily removed after welding. As the arc is completely covered by the flux layer, heat loss is extremely ...

Since in this process, welding arc and the weld pool both are completely submerged under mound of granular fusible and molten flux; therefore, it is called submerged arc welding. During welding, granular flux is melted from the heat generated by arc and forms a shield/cover of molten flux layer (Fig. 13.1 ).
Shielded Metal Arc Welding (SMAW), commonly known as stick welding, is a pivotal manual arc welding process. It employs a consumable electrode enveloped in a flux to fuse metals together. Renowned for its versatility and simplicity, SMAW has earned its place as one of the most widely used welding techniques globally.
1. Introduction. SAW is a unique welding method since it involves the arc which is completely submerged under the layer of granular flux. During welding, this flux that contains lime, SiO 2, MnO, CaF 2 and other compounds reacts with the contaminants in the molten weld metal and forms slag. Thus, slag is considered as waste material.
