100kg Welding Positioner, Rotary Welding Turntable for Pipe Flange Circumferential Welding

The 100kg Welding Positioner is a compact rotary welding turntable specially designed for small cylindrical workpieces, pipes, flanges, and small pressure vessel girth welding. It features a horizontal rated load of 100kg and is equipped with VFD stepless speed rotation, foot pedal control, and a worktable with a central through hole. The machine can tilt 0–90° to adjust the workpiece into the ideal flat welding position, greatly improving welding quality and saving labor costs. It is widely matched with MIG, TIG, and MAG welding sources for circumferential seam welding. CE certified, with a small footprint and easy mobility for metal fabrication workshops.

1. Rated horizontal load up to 100kg with a compact heavy-duty steel frame, providing stable bearing capacity for small vessel and flange circumferential welding.
2. VFD stepless rotation speed adjustment ensures smooth rotation without vibration, making it convenient to set the proper speed for different girth welding requirements.
3. Worktable with a central through hole allows long pipes to pass through, perfect for pipe flange welding and continuous circumferential seam welding.
4. 0–90° tilting function adjusts the workpiece to a flat welding position, reducing welding spatter and guaranteeing uniform weld bead quality.
5. Foot pedal control enables hands-free operation, allowing the operator to focus on welding torch operation and improve workshop welding efficiency.
6. Simple control panel with forward/reverse rotation and emergency stop button, safe and easy to operate for both new and experienced welders.
7. Small size and light weight, flexible to place on a workbench, and easy to match with a welding torch holder for a semi-automatic welding solution.

1. Circumferential girth welding for pipes and flanges, widely used in pipeline fabrication and pipe fitting workshops.
2. Small pressure vessel and thin-wall tank shell circumferential seam welding for metal tank manufacturing.
3. Welding of round barrels, small cylinders, and rotary workpieces for hardware and mechanical parts production.
4. Handrail, lamp post, and small tubular structural component welding in steel structure fabrication factories.
5. Stainless steel small vessel welding for the food, water treatment, and pharmaceutical equipment industries.
6. Machined parts, valve bodies, and rotary workpiece welding, convenient for assembly and inspection after welding.
7. Batch small workpiece welding for job shops, matched with MIG/TIG welders to build a simple automatic welding station.

1. Rotary worktable: Cast iron plate with mounting holes and a central through hole for fixing workpieces and chucks.
2. Rotation driving unit: Motor and precision gear reducer to drive table rotation for circumferential seam welding.
3. Tilting frame: Heavy steel bracket to support the table and realize 0–90° tilting adjustment.
4. VFD control cabinet: Frequency converter, buttons, and display screen to control rotation speed and direction.
5. Foot pedal controller: External foot switch to start or stop turntable rotation conveniently during welding.
6. Safety protection components: Emergency stop button and overload protection device to protect the machine and operator.
7. Optional 3-jaw chuck: Self-centering chuck for fast clamping of round pipes, flanges, and cylindrical parts.
