Currently in stock at our works in Leicestershire, UK we have a large variety of sub arc welding equipment.
Suitable for a variety of applications and industries.
The Process.
Sub arc welding is defined by the use of a layer of granular flux that is applied by a flux hopper. It helps to aid temperature control, eliminating cracking and contamination in the weld, making it stronger and more resistant.
For a full description of submerged arc welding, the TWI have a great one on their website.
SAW is mainly used in the production of longitudinal & circumferential butt and fillet welds when manufacturing large steel structures, cans and vessels for industries such as nuclear and oil and gas (onshore and offshore).
Equipment.
