High-Efficiency Welding Processes
-
FCB efficient submerged arc welding process
FCB method, also known as flux-cored copper backing, is to evenly lay backing flux with a thickness of 4~8mm on copper plates in a plate-like shape.

FTI method for high-efficiency submerged arc welding process
FTI welding refers to the double-wire double-sided single-pass submerged arc welding process. I-shaped grooves are used for joining steel plates with a thickness of 25mm or less, while Y-shaped grooves are used for joining plates with a thickness greater than 25mm. Welding is applied on both sides with one pass each.

FGB method for high-efficiency submerged arc welding process
The FGB welding process involves adding alloy powder to the groove, then applying backing material on the backside, and covering the surface with sintered flux.

Efficient submerged arc welding process for thick plates
This method is a highly efficient submerged arc welding process derived from the FCB and FGB. It uses the FCB method to weld with three electrodes simultaneously and fills the groove with alloy powder to achieve double-sided single-pass welding for a maximum plate thickness of 100mm.
