About This Product

Buried arc in high current range achieves high efficiency and quality in thick plate welding

■What is Buried Ark?

Buried arc is low voltage carbon dioxide arc welding. This is a condition where the wire penetrates into the molten metal due to the high arc force and an arc is generated. Because the base metal is heated deep inside, deeper penetration can be achieved compared to regular welding.

■Arc stabilization technology in high current range in carbon dioxide arc welding

Daihen's unique precision waveform control technology has succeeded in stabilizing the arc, achieving high current buried arc welding (D-Arc welding). Conventional arcs become unstable and the current cannot be increased, but D-Arc allows stable welding even in high current ranges.

■Advantages of D-Arc welding

1. Stable welding is possible even in the high current range, which was previously avoided. Contributes to increased efficiency. ・If the number of passes cannot be changed, increase the welding current and speed to shorten the welding time even if the number of passes remains the same. ・If there is no limit to the number of passes, increase the welding current to increase the amount of welding, and reduce the number of passes to shorten the welding time. 2. Reduction of spatter removal man-hours: "Buried arc" is an arc that occurs within the base material, which reduces the amount of large spatter that emerges on the surface. 3. Improved welding quality: Since the penetration is deeper than normal DC CO2 welding, the root can be thoroughly melted even with the same current setting, making it ideal for areas where poor penetration is likely to occur and requires a UT test. .

■Acquisition of “Architectural Technology Performance Certification” from Japan Building Research Center (GBRC)

The construction using D-Arc welding has been proven to meet the required welding quality for welded joints of architectural steel frames. *Tensile strength/yield point: Base metal or higher, Charby: 27J (0℃) or higher (welded metal)

■System configuration

・Semi-automatic specification Depending on the application, only one welding power source (single) or two welding power sources can be operated in parallel (parallel). ・Robot and automatic machine specifications Features

■Semi-automatic: Welding current around 500A

Achieving high efficiency in thick plate welding: By applying D-Arc mode to multi-layer welding, the number of passes can be reduced, making welding work highly efficient. Although the groove shape remains the same as before, D-Arc with high welding properties reduces the number of welding passes and reduces welding time by 55%.

■Semi-automatic: Welding current around 350A

High quality welding achieved by D-Arc mode
