Arc welding robots refer to industrial robots used to perform automatic arc welding. The composition and principle of the arc welding robot are basically the same as those of the spot welding robot. Arc welding robots are mainly used in the welding production of various types of auto parts.
Arc welding robot system composition
The general arc welding robot is composed of a teaching box, a control panel, a robot body, an automatic wire feeding device, a welding power supply and other parts. Continuous trajectory control and point control can be realized under the control of the computer. Linear interpolation and circular interpolation can also be used to weld spatial welds consisting of straight lines and arcs.
The basic composition of the arc welding robot system is as follows: robot body, control system, teach pendant, welding power supply, welding gun, welding fixture, and safety protection facilities. The system composition can also be selectively expanded according to the different welding methods and the different welding process requirements of the specific workpiece to be welded: wire feeder, cleaning gun wire cutting device, cooling water tank, flux delivery and recovery device (SAW), mobile device, welding positioner, sensing device, dust removal device, etc.
Features of arc welding robots
1. Stabilize and improve the welding quality to ensure its uniformity. When using robot welding, the welding parameters of each weld are constant, and the quality of the weld is less affected by human factors, which reduces the requirements for the operation technology of workers, so the welding quality is stable. However, in manual welding, the welding speed and dry elongation are varied, so it is difficult to achieve quality uniformity.
2. Improve the working conditions of workers. The use of robot welding workers is only used to load and unload workpieces, away from welding arc light, smoke splashing, etc.
3. Improve labor productivity. The robot has no fatigue, can produce continuously 24 hours a day, and with the application of high-speed and efficient welding technology, the efficiency is improved more obviously by using robot welding.
4. The product cycle is clear, and it is easy to control the output of the product. The robot's production cycle is fixed, so the production schedule is very clear.
5. It can shorten the cycle of product replacement and reduce the corresponding equipment investment. It can realize the welding automation of small batches of products. The biggest difference between the robot and the special machine is that it can modify the program to adapt to the production of different workpieces.
There are two main types of arc welding robots: melting pole welding operations and non-melting pole welding operations, which have the characteristics of long-term welding operations and high productivity, high quality and high stability of welding operations. With the development of technology, arc welding robot people are developing in the direction of intelligence.
