Automatic Pipe To Flange Welding Machine

Device Type

Automatic girth welder (mainstream): The steel pipe is fixed, the welding gun rotates, and 360° continuous welding is achieved, which is suitable for mass production.
Gantry welding machine: Large diameter flange welding, equipped with multiple gun heads, high efficiency.
Robot welding workstation: Flexible production, suitable for multi-specification flange welding (need to be equipped with a positioner).
Manual/semi-automatic welding machine: Cooperate with welder operation, suitable for small batches or maintenance scenarios.

Welding processes

MAG welding (CO₂/mixed gas shielded welding): low cost, high efficiency, suitable for carbon steel flanges.
TIG welding: stainless steel, alloy steel flanges, high weld quality.
Submerged arc welding (SAW): high penetration welding of thick-walled steel pipes.
Laser-arc hybrid welding: high precision, low deformation, used in high-end fields.

Core components

Welding power source: digital MIG/MAG, TIG or submerged arc welding power source.
Rotating mechanism: The head and tail frames clamp the steel pipe, and the servo motor drives the uniform rotation.
Flange positioning fixture: hydraulic or pneumatic clamping to ensure the verticality of the flange and the steel pipe.
Control system: PLC programming, storing multiple sets of welding parameters (current, voltage, speed, etc.).

Technical features
✔ High efficiency and stability: the automatic welding speed is stable.
✔ Strong adaptability: can weld carbon steel, stainless steel, alloy steel, etc.
✔ High weld quality: no defects such as pores and lack of fusion, and can be detected by X-ray or ultrasonic.
