TBM-65 Tube-to-Tube sheet Automated Welding Head
Production Information
The KEPUNI TBM-65 is a precision-engineered welding head optimized for all-position automatic orbital welding of tube-to-tube sheet joints, offering enhanced accuracy and operational efficiency in industrial applications.
Key Specifications:
Welding wall thickness: 0.5-5mm
Welding head adjustment angle: 0°-60°
Welding pipe diameter:22mm-65mm
Welding head cooling method: Circulating water cooling
Advanced Features:
Cylinder mid-mounted technology
Compared with the traditional rear-mounted cylinder, the center-mounted cylinder can make better use of space and provide support for coaxial wire feeding.
Coaxial wire feeding integrated technology
Place the wire reel at the back so that the wire has enough space in the gun to be straightened, and the wire comes out without bending or warping, with good stability.
Adjustable modules
Utilizing five slide rails and a 60° turning device, the welding torch and wire feed port can be moved relative to each other and as a whole, and the inclination angle of the welding torch can be adjusted.
Narrow pitch welding
The design of adjustable three-dimensional modules can minimize the pipe bridge spacing to 6mm when welding dense pipe arrays.
Applications:
Power Generation: Welds boiler tubes, heat exchangers, and steam condensers.
Petrochemical: Repairs process piping and reactor vessels.
HVAC: Fabricates chiller coils and condenser tube joints.
By integrating automation, precision controls, and operator-centric design, while meeting ASME Section IX and ISO 15614-1 standards.
