The full-position automatic welding machine trolley can realize constant speed walking along the outside diameter of the pipe, up and down step adjustment of the height of the welding gun, fine tuning of the welding gun, left and right swing of the welding gun, left and right welding stay of the welding gun, welding current and voltage control.
1, The main body of the crawler trolley is made of aviation aluminum alloy, with an overall weight of about 14KG, which is convenient to carry in site construction, light in structure and high in strength;
2, The main design size of the crawler trolley is compact, and the rotating space within 300mm around the pipeline can meet the requirement of rotary welding;
3, The walking motor, the oscillating motor and the raising motor of the crawler are all equipped with an orthogonal encoder to achieve position feedback and speed feedback, ensuring accurate position positioning accuracy and speed accuracy, as well as better dynamic performance and output torque
4, welding gun swing and position adjustment using stepper motor, stepper motor can achieve accurate positioning characteristics, to ensure the width of swing, residence time and high and low attitude control accuracy.
5, The welding power supply adopts digital gas shielded welding power supply, and all welding parameters adopt digital processing, so there is no need for manual intervention in the welding process.

7, Welding power supply: imported from Sweden issa digital gas welding power supply, to achieve the welding material in the welding pool of accurate transition control.
1, the LCD screen + intelligent waterproof soft button control, used for welding program preset, display and parameter fine-tuning, hand-held control box with waterproof design to avoid sweat into the function failure.
2, We developed a new generation of all-position automatic welding machine, crawling trolley walking using our company's special
development of constant torque motor drive, whether downward welding or upward welding, can maintain the speed of crawling welding constant, greatly improve the quality of welding stability the fourth generation wire feeding machine, wire feeding rolls, special welding torch directly integrated installation on the trolly, such as more compact structure, adopts the design of the cable without welding torch, welding torch, wire feeding machine, all in a car, does not exist when welding torch wire bending problems, greatly improve the welding electric arc stability, at the same time by reducing the wire feeding machine parts made of independent equipment overall quality lighter;
3, using CPLD microelectronic digital integrated circuit and FPGA chip as the core controller, to achieve the control of the motor, I/O interface control and all the operations. FPGA chip's high speed operation and timely sequence logic function performance ensure that each motion control and related operation can be completed in a very short time.With X axis straight pendulum and two axis composite pendulum function, regardless of wall thickness, wall thickness, groove girth weld or fillet weld can achieve excellent welding quality;
4, High clarity LCD screen page in the face of "welding parameters setting page" and "monitoring page" to distinguish, to facilitate the setting of process parameters before welding, welding finished switching to the "monitoring page" for real-time observation of welding parameters dynamic, at the same time effectively avoid the welding process in the wrong operation
