Open Weld Heads

  
 

     
 MU IV    MU IV 195 HW
     
For standard or special applications
Perfectly adapted for joining small and medium wall tubes and pipes out of all weldable materials. The head clamps on one side of the weld joint. During welding, the head body remains stationary, the torch rotates around the tube.
TIG / GTAW cold wire welding of tube to tube joints (O.D. from 8 mm/0,3” to 275 mm/11”)










 
For multipass TIG Hot Wire welding of tubes and pipes high-performance
TIG hot wire increases the deposit rate by more than 3:1.Compared to TIG cold wire orbital, TIG hot wire orbital welding is particularly advantageous for medium and heavy wall thicknesses. Full function weld head with AVC and torch oscillation. Perfectly adapted for
joining medium and heavy wall tubes and pipes out of all weldable materials. The head clamps on one side of the weld joint. During welding,the head body remains stationary, the torch rotates around the tube.
TIG / GTAW hot wire welding of tube to tube joints (O.D. from 76mm/3” to 195mm/8”)

For multipass TIG welding of tubes and pipes
Perfectly adapted to tube and pipe welding of medium and heavy wall thicknesses, narrow gap welding up to 100 mm (3.9") groove depth. The weld head travels around the tube on a premounted guide ring. Guide rings are available for all tube and pipe sizes. The full function weld head reproduces all motions of a skilled manual welder and completes the weld in a series of passes.

TIG / GTAW cold wire / hot wire welding of tube and pipe joints (O.D. >= 168 mm/6")






  For small and medium wall tube and pipe thicknesses
 
Full function welding heads with AVC and torch oscillation. Perfectly adapted for joining small and medium wall tubes. The welding head travels around the tube on a premounted guide ring. Guide rings are available for all tube sizes. The full function welding head reproduces all motions of a skilled manual welder and completes the weld in a series of passes.

TIG cold wire process - welding of tubes (O.D. from32mm/1.26"
to 168mm/6")
     
     
     

     
 POLYCAR 60-2    POLYCAR MP / Pipe
     
For "large diameter" pipes
Perfectly adapted for joining medium and heavy wall tubes and pipes out of all weldable materials. The weld head travels around the tube on a premounted guide ring. Guide rings are available for all tube and pipe sizes. The full function weld head reproduces all motions of a skilled manual welder and completes the weld in a series of passes.
TIG / GTAW cold wire / hot wire welding of tube and pipe joints (O.D. >= 114 mm/4")




  For multi process
The full function weld head can be used with various arc welding processes and groove designs. Perfectly adapted for joining medium and heavy wall tubes and pipes out of all weldable materials. The weld head travels around the tube on a premounted steel band.
TIG / GTAW cold wire / hot wire welding for large or narrow groove designs
MIG-MAG/GMAW/FCAW V-bevel with or without gap / U-bevel without gap
Plasma / Butt welding
