In view of the problems in the trial process, combined with the raw materials, shape characteristics, scale accuracy requirements, weld length and position characteristics, welding workload and robot working power, the welding robot system selects the full digital pulse gas maintenance welding power supply, namely pulse MIG welding process power supply.
As we all know, the accuracy of arc control in the welding process determines the better the welding quality. Because the digital technology is used in the full digital pulse gas maintenance welding power supply, the reaction time of the control system is reduced by several orders of magnitude compared with the traditional welding machine, which improves the accuracy and sensitivity of the reaction.
In the selection of pulse welding, it can provide the appropriate pulse waveform, and can also be used to control each pulse to transfer only one droplet, which makes the arc length remain unchanged in the whole welding process, there is almost no spatter in the welding process, and the welding with ultra-low heat input can be completed. Together, it can overcome the traditional GMA welding machine. After welding, the end of the welding wire will form an influence Because of the disadvantage of arc striking, the best match between welding quality and welding power is achieved.
Welding robot connecting plate is a common part of construction crane, which is mainly composed of base plate and four pin columns. The welding method of circumferential fillet weld is used to fix the pin column and the base plate. In the past, the welding process of CO2 gas maintenance plus flux cored wire is used. Because the weld is a circular fillet weld, so
The connecting plate is a common part of construction crane. Its structure is shown in Figure 1, which is mainly composed of bottom plate and four pin columns. The welding method of circumferential fillet weld is used to fix the pin column and the base plate. The previous welding method adopts the welding process of technical CO2 gas maintenance and flux cored wire. As the weld is a circular fillet weld, it is easy to form defects such as poor weld appearance quality, low welding power, poor combination of weld ring line and welding part loop line, and easy to form "desoldering" In addition, in order to ensure the appearance quality of the weld, it is necessary to select a grinder to grind the weld after welding, which is easy to add welding cost. After analysis, it is decided that the welding robot should be selected for welding operation. The key is to plan a reasonable welding robot operating system and formulate a reasonable welding process to ensure the cost and quality are consistent.

Methods to reduce welding deformation and control
I. causes and types of welding deformation causes of welding deformation: welding deformation refers to the deformation of weldments during and after welding. During welding, the molten metal and the base metal near the seam expand and produce plastic deformation. During solidification, the weld and the metal near the seam contract. This is the longitudinal stress and the transverse stress. Make the weld longitudinal and transverse shrinkage, so that the weldment deformation. Because the heat e
Specific differences between grinding machine and polishing machine
Difference: the workpiece processed by grinding machine is rough, and the surface finish of workpiece processed by polishing machine is better, but high finish can be achieved by installing precise grinding wheel on grinding machine. Grinding machine: electric grinder reciprocating electric polishing grinder (also known as file mill). It is widely used in the fine machining and surface polishing of the mold profession. It is a substitute for similar pneumatic products. The main outstanding featu
How to improve the efficiency of straight seam welding machine?
The straight seam welding machine is widely used in ordinary times, and our appeal to the seam welding machine is constantly strengthened. We should know about the operation of the seam welding machine. The straight seam welding machine is not only excellent in spot welding machine, but also excellent in seam welding machine. A good machine must be equipped with a good operator. It is not simple to be a good operator. In addition to the accumulation of time experience, it also needs many tips, s
How to deal with the failure of welding robot?
General welding robot factory has the following shortcomings: a) human shortcomings caused by improper operation, mainly including welding gun damage in welding robot factory, improper loading and unloading of workpieces, and no deformation of positioner follow-up. B) the disadvantages of poor design and manufacture of peripheral equipment mainly include: problems of lifting way switch and cable, quality problems of some components flashed by teaching device. C) improper environmental protection
