Narrow gap welding is an advanced technology in the field of thick plate welding, suitable for welding the outer longitudinal and circumferential seams of pressure vessels and thick walled shaft workpieces in nuclear power, petrochemicals, heavy machinery, etc. perfect for wind tower, boilers and shipbuilding manufacturers. It provides the possibility of welding at points with high and long distances. Compared with submerged arc welding with ordinary grooves, narrow gap welding has unparalleled advantages. If the groove is narrow and the amount of metal filling in the weld seam is small, it can save a lot of welding materials and welding time.


DIG Benefits
Precision: Fully programmable. Ensures consistent welds with precise control through movement of the welding head.
Safety: Reduces the need for operators to work in hazardous positions, minimizing the risk of injury.
Absence of visible arc and ease of penetration. High deposition rates and deep penetration.
Narrow groove welds have less metal filling, which can save a lot of welding materials and welding time
Narrow gap welding has a lower heat input, which significantly refines the microstructure of the weld metal and heat affected zone, thereby improving their mechanical properties, especially plasticity and toughness
Versatility: Adaptable for various welding processes and can be customized with different welding heads and tools.
