An arc welding robot is an industrial robot used to perform automatic arc welding. The composition and principle of an arc welding robot is basically the same as that of a spot welding robot. Arc welding robots are mainly used in the production of welding of various automotive parts.
Arc welding robot system composition
A typical arc welding robot is composed of an instruction box, control panel, robot body and automatic wire feeding device, and welding power source. Continuous trajectory control and spot control can be realized under the control of a computer. It can also weld spatial seams consisting of straight lines and circular arcs using linear interpolation and circular interpolation functions.
The basic components of an arc welding robot system are as follows: robot body, control system, trainer, welding power source, welding torch, welding fixture, and safety protection facilities. The system composition can also be selectively expanded according to the different welding methods and the specific welding process requirements of the workpiece to be welded, such as the following devices: wire feeder, gun cleaning and wire cutting device, cooling water tank, flux delivery and recovery device (SAW when), mobile device, welding positioner, sensing device, dust removal device, etc.
Features of the arc welding robot
1、Stabilize and improve welding quality and ensure its uniformity. When robot welding is used, the welding parameters are constant for each weld, and the quality of the weld is less affected by human factors, reducing the requirements for workers' operating techniques, so the welding quality is stable. While manual welding, welding speed, dry elongation, etc. are variable, so it is difficult to achieve uniformity of quality.
2、Improved the labor conditions of workers. Using robot welding workers are only used to load and unload work pieces, away from the welding arc, smoke private spatter, etc.
3、Improve labor productivity. Robot does not have fatigue, a day can be 24h continuous production, in addition, with the application of high-speed and efficient welding technology, the use of robotic welding, efficiency improved more obviously.
4、The product cycle is clear, easy to control the product output. The production beat of the robot is fixed, so it is very clear to arrange the production plan.
5、It can shorten the cycle of product replacement and reduce the corresponding investment in equipment. Welding automation of small batch products can be realized. The biggest difference between the robot and the special machine is that he can modify the program to adapt to the production of different workpieces.
There are two main types of arc welding robots: molten pole welding and non-melted pole welding, which are capable of long-term welding operations, high productivity, high quality and high stability. With the development of technology, the arc welding robots are developing in the direction of intelligence.
