automatic welding machine for circumferential and longitudinal seam

The automatic welding machine is controlled by PLC, which has high welding efficiency. The operator can weld the perfect weld without knowing the welding technology. The welding efficiency is high and the welding quality is good. The welding output of an automatic welding machine is equivalent to the output of four manual welding workers, and the welding quality is stable, which is not affected by artificial emotions and technology. All operations are controlled by PLC. The touch screen can set the relevant data of the welding machine and can be saved in the system. The next time the welding machine is of the same model, only the data in the computer needs to be called, no need to input again. The rotation, shutdown, welding delay, gun stopping buffer, arc starting and arc stopping are completely controlled by the program.

The welding machine can be equipped with argon arc welding machine, plasma welding machine and carbon dioxide protection welding. The welding power supply can be micro plasma, AC, DC and inverter.

Features of girth welding machine:

◇ pneumatic clamping and positioning, pneumatic gun lifting and delivery, with stable and rapid up and down speed.

◇ single gun, double gun or multiple guns can be welded at the same time, saving time and improving work efficiency.

◇ the rotary head is driven by DC motor or AC variable frequency motor, with stable operation and uniform and beautiful weld formation.

◇ imported or domestic famous brand PLC core, low failure rate, stable and reliable performance.

◇ the bed adopts horizontal structure, which is made of welded structural parts after annealing, to ensure that the guide rail of the bed is not deformed.

◇ the end of the spindle is equipped with a welding fixture or three jaw chuck for clamping and positioning the workpiece.

◇ the tailstock is pneumatically tightened, and different welding clamps or movable centers can be selected at the end according to different workpiece forms.

◇ the tailstock slides on the guide rail of the bed, and the distance between the head and tailstock can be adjusted to adapt to the workpiece of different lengths.

◇ the welding gun mechanism moves to the corresponding position along the guide rail direction according to the different welding positions of the workpiece.

Human machine interface control, digital parameter processing, simple and convenient operation.

◇ the welding power supply can select MIG / CO2 according to the workpiece material.

Pipe flange automatic welding machine series tooling

Equipment Overview

For many years, Wuxi Lingrui Welding Technology has been committed to the research and development and production of automatic welding equipment for pipe flange products. The equipment is widely used in pipelines, water treatment equipment, pressure vessels, food machinery, environmental protection equipment, shipbuilding and other industries. Pipe fittings and pipe fittings, pipe fittings and flanges, pipe fittings and elbows, pipe fittings and tees and other structural products are automatically welded. The materials include carbon steel, stainless steel, aluminum, titanium alloy and other materials. The welding method can be argon. Arc welding (tig), plasma welding (PLAWS), gas shielded welding (MAG/MIG), submerged arc welding (SAW), welding can realize single-sided welding and double-sided forming. The equipment adopts touch screen and plc integrated control, with high degree of automation, convenient operation and advanced technology, which can meet the high-efficiency production needs of users!

Weldable Workpiece Type

Welding Process

You can choose any one of the following welding processes or multiple welding processes for combined welding:

• Argon arc welding (tig)
• Hot wire argon arc welding (quality of ordinary tig, speed of MiG welding
• Gas shielded welding (CO2/MAG/MIG)

Welding Quality

• The weld seam is beautifully formed, and the welding pass rate of radiographic or ultrasonic testing reaches 98%
• Welding meets various testing requirements such as water pressure, stretching, bending, impact and metallographic analysis
