TT-69 unit for contact longitudinal roller welding is designed for welding of longitudinal seams of parts with a length up to 200 mm. Welding is performed in overlapping manner. Welding of longitudinal seams of cylindrical parts is possible.
The unit comes standard with equipment for welding of specific parts.
The unit can be used for welding of longitudinal seams on various alloy workpieces.
Thickness of a welding part should be up to 0.8 mm.
Workpiece is installed in special equipment (mandrel) or directly on longitudinal substrate. Electrode wheel and clamping roller are pressed down by special lever to workpiece by force which is set by pre-loaded springs. After start button is pressed welding cycle begins with given parameters of welding impulses, welding speed and pitch of weld.
