track

*Crawling drive: constant torque motor + high precision planetary reducer + worm gear and worm drive;

*Swing drive: stepper motor + high precision planetary reducer + high precision linear slider;

*Height adjustment of welding torch: stepper motor + high precision planetary reducer + high precision linear slide rail;

*Trolley structure: frame structure, made of aviation aluminum alloy;

*Control features: high-definition LCD screen input parameters, realization of pipe 360 ° 12 welding range, accurate setting each interval of welding technology, digital integrated circuit with CPLD microelectronics and the FPGA chip as the core, the implementation of various motor movement parameters and precise matching of welding current, welding voltage, etc;

*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.

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.

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.

*Based client's facility/site space availability, we are able to study/design and present matched configurations on project schedule, quality, cost and productivity to guarantee production pace is accordance with project requirement.

*To support project execution, we are always ready to work as fireman to give prompt supply on project material from different consumables, tools, equipments/machines to special merchandise. With flexibility, we are also glad to perform as procurement agent in China to seek required supply resources.
