Water Heater Double Circular Seam Welding Machine

1. Welding torch is fixed while workpiece rotating. Welding position is horizontal. The workpiece is clamped tightly by fixture and rotates.
2. Two welding torches and two power sources work simultaneously to improve work efficiency.
3. Torch, rotary axis box and tailstock can be adjusted longitudinally to fit various kinds of welding.
4. Japan Omron PLC is adopted to control the machine to run and speed is adjusted by AC servo, which can improve the reliability of the equipment.
5. Adopts end face positioning and pneumatically clamping mode.
6. Adopts human-machine interface to alter the parameters. The welding time and weld length can be set via this interface. The alteration of the parameters can be input through the touch button conveniently and timely. Parameters can be stored and called.

1.Two sets of welding guns and adjustment devices are installed on the left and right sides of the machine tool, which are pneumatically moved up and down to switch the welding gun between the preparation position and the welding position. The swing mechanism allows the welding gun to swing left and right according to the pre-set parameters, thus making the welding quality more beautiful.

2.During the welding process, a pneumatic device generates sufficient clamping force to securely fix the cylinder in its designated position, driving the workpiece to rotate smoothly and at a constant speed around its axis. Meanwhile, the welding torch remains fixed in place. This automated "workpiece rotates, welding torch remains stationary" mode efficiently and accurately completes the two circumferential welds at the connection between the cylinder's two ends and the end cap in a single pass.

3.Integrated control panel. Control buttons, touch screen and welding parameters are all integrated on one panel, which is convenient to use and operate.

4.Located to the right of the clamping fixture, this support rack provides stable support for the cylindrical workpiece during double-girth welding. Working in conjunction with the left-hand clamping fixture, it ensures precise alignment of the workpiece during rotational welding, effectively suppressing offset vibration caused by the cylinder's own weight. Its height-adjustable mechanism accommodates varying cylinder diameters. Its rigid support structure and rolling roller design reduce friction and ensure alignment between the workpiece's rotational axis and the welding trajectory, ultimately guaranteeing both girth weld quality and process stability.
