Oil Tank And Pipe Welding Rotator , Tank Longitudinal Seam Welding Machine
Automatic Longitudinal Seam Welder series are mainly used for welding longitudinal seam of thin sheet. It adopts cantilever type, and it is mainly composed of frame, fingers-type clamping unit, water-cooling mandrel, travelling carriage, crossing slider, wire feeder and torch holder. Fingers-type clamping unit owns special push from air cell, pressure of air cell is adjusted between 0 to 7kg/cm2, and the distance of two banks of fingers between 5 to 20mm to satisfy various welding seam width; Water-cooling mandrel is designed according the work pieces' diameter and length to ensure the strength. The top of mandrel is inserted water-cooling insert with groove for heat-sink cooling. It is adjustable in mandrel height to handle various material thicknesses. Beam is fitted with travel carriage which is moved straightly by track and driving unit, variable speed.
