l in the automatic welding system, in order to achieve to improve the welding efficiency is often necessary to make multi-position automatic welding, including feeding, fixturing, welding, cooling-bit or check bit, the next level, thus forming a complete automation system, a one-time completion of the work piece from the assembly, welding, the work of the detected output. The right is a car Ejector board a three-position automatic welding machine, feeding level, soldering bit, check bit. By the Welding Rodsautomatic welding system which is often used duplex or multi-position welding, in the long arm of the robot within the coverage area, the conversion from one station to another station, in order to achieve the multi- bit welding.
 Parts of the Welding Materials, often including one or more of the weld, and often include multiple parts welding a part. For example, our common water heater, car storage pump cylinder, etc., including steel plate rolling straight seam welded to both ends of the head and cylinder girth welding, faucets or outlet nozzle and the cylinder or end cap ring liner or cylinder rack welding seam welding, and welding to complete a part, that the water heater or storage pump. To achieve each welding done automatically, the need to convert automatically from a station to another station, thus forming a water production operations, automatic welding.

  An open-loop control type
Class welding machine control systems generally use the open-loop control, the control system to pre-set parameters, and by the actuator by the control program sequence. Simple structure of such equipment, technical requirements and costs are relatively low, so get a lot of use. In the welding process, Aluminium Welding Rodfluctuations can not be a closed loop feedback control, the movement of the welding head or welding workpiece can only be carried out in accordance with the pre-specified path or track, can not change with the changes of the workpiece weld, therefore, during use, should ensure the consistency of the workpiece and the weld with precision in order to improve the reliability of the welding efficiency and product Types Of Welding Rod. Such as the right is the robot to automatically flip the welding machine, welding machine by CNC control system software pre-set to the robot manipulator automatically flip welding machine
(Gripping the torch part) to move the track and platform flip angle, butt multiple points, lines, surfaces, and full automatic welding of the pre-set program. The open-loop control of welding procedures for pre-set, the torch movement errors due to workpiece automatically adjust the action away adaptation weldment error. The need workpiece closely with the same, each to be weldment to ensure that the same or within the error, otherwise it can not Auto-completion of all welding work.
2, the adaptive control
Class plane is a high degree of automation of the welding equipment. It is equipped with sensors and electronic detection circuit automatically oriented and tracking the trajectory of the weld, some devices can also achieve closed-loop control of welding parameters such as welding current, welding voltage, welding speed, the entire welding process at a pre-set procedures and processes parameter is automatically completed. For example, a larger cylinder or tube parts, as shown, trailer beam automatic welding machine
To ensure the consistency of the workpiece and reached a high fitting accuracy is very difficult, takes a much higher cost. The welding machine with arc length tracking and torch swing. Torch with the uneven surface of the workpiece due to the uneven surfaces of the workpiece surface, the need for moving up and down in order to maintain the distance of the torch and the workpiece surface, thus ensuring the stability of the arc. Automatically to achieve the multi-layer welding. Welding two layers, welding after a week, tracking the detected surface height increase, you can automatically torch improve.
3, intelligent
It uses various types of sensor, such as vision sensors, antennae, sensors, light sensors, and the use of computer software systems, databases, expert systems and the recognition, judgment, real-time detection, computation, automatic programming, welding parameters call operation only need to enter the grades of the material on the man-machine interface thickness, the groove, wire grades and diameters, flux or type of shielding gas, welding parameters automatically generated or call the corresponding parameters. To complete the automatic welding. Due to the cost of such equipment is very high, the actual impact welding quality of many factors, such as gas purity, flow rate, welding current, voltage, power input fluctuations, moisture or corrosion of the workpiece, the weld width, weld the level of difficult to really complete the intelligent welding, rarely used in actual production.
