As a leading precision and custom fabrication company, we employ advanced welding techniques and equipment to ensure the highest quality finished products for our clients. A new addition to our toolbox is submerged-arc welding (sub-arc welding) (SAW). SAW involves the use of a continuously fed electrode to create an arc that is shielded by a granular flux that is deposited over the weld zone. The flux melts to form a slag, which protects the weld from atmospheric contamination and provides a smooth, clean finish.
Advantages to SAW
Sub-arc welding is a highly efficient welding process capable of producing high-quality welds at a very high deposition rate. Other key advantages include deep penetration and fusion, and consistently uniform welds. This makes it particularly well-suited for welding thick materials. Additionally, the use of a flux shield helps to reduce the risk of defects such as porosity, cracking, and spatter. Coupling submerged-arc welding with a positioner or drive rolls provides smooth, continuous welds that can be deposited in a short period of time with no need for stopping until the weld is complete. This helps speed up production and efficiency while yielding fantastic results.
