Submerged arc welding (SAW) is an innovative metal joining technique that has revolutionized the manufacturing process for a myriad of metal components. According to reports, the global SAW market has grown at a compound annual growth rate (CAGR) of
5% since 2019 and is projected to reach a market size of $25 billion by 202 While this welding method has been around for decades and is used in the production of aircraft, cars, ships and heavy machinery, it is becoming increasingly popular as manufacturers look for ways to minimize costs and enhance efficiency.
So, what is submerged arc welding and why is it becoming so popular? To answer this question and learn about the inner workings of this method, let’s dig into a detailed discussion about submerged arc welding!
What is Submerged Arc Welding (SAW)?
Submerged Arc Welding (SAW) is a welding process in which the entire arc is submerged in a flux-filled fuming chamber.It is also known as Sub Arc Welding, Sub Arc Welding, Sub Arc Process and Sub Arc Welding Process. SAW is a well-established welding process which is widely used in the welding of construction steels, shipbuilding steels, high-strength low-alloy (HSLA) steels, stainless steels and pipe steels among others.
Applications of Submerged Arc Welding
The process is extremely popular in industries where high-quality welds are required consistently and quickly.SAW is used in a variety of applications, from shipbuilding to train carriages, as well as in component fabrication, building construction and pipelines. Its thermal efficiency and its capacity for consistent production make it an attractive solution for mass production or intricate structures.
Advantages of Submerged Arc Welding
The main advantages of SAW are:• High deposition rate.• High welding speed. • Deep penetration.
• Low distortion. • Smooth finish.
• High productivity. • Ability weld in all positions. • Low spatter.
• Low heat input. • Low environmental impact.
