Adapted from 0 to 100 mm wall thickness. The V2-Nozzle has the particular feature of being insulated and channelling the gas directly into the groove.
Family: Equipment for Narrow Groove welding
Narrow Groove TIG welding – an essential process
POLYSOUDE has a comprehensive line of “Narrow Groove” welding torches for all wall thicknesses up to 300 mm and more.
Each torch has a range which enables it to be used from maximum wall thickness (maximum torch insertion depth into the groove) up to completion of surface capping runs.
Two essential approaches and their advantages shall be examined:
– Single stringer bead per layer
– Single oscillation pass per layer
Conventional torch
Adapted for wide & narrow groove applications from 0 to 45mm wall thickness
OSC-Electrode
A line of 3 torches for wall thicknesses from 0 to 150 mm, 0 to 200 mm and finally 0 to 300 mm, with trailing shield assembly for all runs from root to cap.
