3 categories of automatic welding robots

The current industrial welding production posts more and more demanding requirements to the welding quality. Therefore, it is getting harder and harder to find the skillful welding technicians and the cost of hiring such experienced welding technicians is getting higher and higher. But luckily, welding robot was successfully invented. It can perform different kinds of welding job with high precision, high quality and shorter time. Based on the welding technique, welding robot can be categorized into spot welding robot, arc welding robot, friction stir welding robot and laser welding robot.

1.Spot welding robot

Spot welding robot features big effective load and big working space. It often comes with specific spot welding gun which can realize flexible and accurate movement. When it first appeared, it was only used for reinforcing welding, but later it is used for fixed-position welding.

2.Arc welding robot

Arc welding robot is widely used in many different industries, such as universal machinery and metal structures. It is a flexible welding system. During the operation of the arc welding robot, the welding gun will move along the weld line and continuously add the metal to form a weld line. Therefore, speed and track accuracy are two important factors in the running of arc welding robot.

3.Friction stir welding robot

During the operation of the friction stir welding robot, due to the vibration, pressure that imposed on the weld line, friction spindle size, vertical and lateral track deviation, higher demand on positive pressure, torque, force sense ability and track control ability for the robot is required.

4.Laser welding robot

Unlike the above-mentioned welding robots, laser welding robot uses laser as the heat source. The common laser sources include fiber laser and laser diode. It has the highest precision and is able to realize big part welding and complicated curve welding. Generally speaking, the major parts of a laser welding robot includes servo-controlled, multi-axis mechanical arm, rotary table, laser head and a small water chiller system. You might wonder why a laser welding robot would need a small water chiller system. Well, it is used for cooling the laser source inside the laser welding robot to prevent overheating problem. An effective cooling system can help maintain the excellent welding performance of the laser welding robot.

S&A Teyu CWFL series small water chiller systems are ideal cooling partner for laser welding robot from 500W to 20000W. They are characterized by dual temperature control, providing individual cooling for the laser head and the laser source. This not only saves space but also saves money for the users. The temperature stability includes ±0.3℃, ±0.5℃ and ±1℃ for selection. Check out the complete CWFL series small water chiller systems at https://www.teyuchiller.com/fiber-laser-chillers_c2

The application of laser welding robot in industrial sector

Laser welding machine has got the popularity among users for many years due to its small heat affecting zone, narrow weld seam, high welding intensity with little deformation left in the work pieces. The laser welding technique gradually becomes mature. However, as users’ needs keep changing and the competition in the laser welding industry becomes more and more fierce, laser welding machines are developed to meet more humanized demands. To meet this demands, laser welding robotwas invented.

Laser welding robot has a wide variety of applications, including sheet metal processing, automobile, kitchenware, electronic engineering, medical or mold manufacturing industry.

Thanks to advantages of deep penetration welding and heat transfer welding, laser welding robot can be widely used. What’s more, laser welding robot can also perform excellent welding on demanding components without post-processing.

In some new applications, laser welding robot can also be applied. Take multi-layer mechanical components as an example. These components will first be cut by laser cutting machine. Then these components will be organized as a muti-layer structure. Then use the laser welding robot to weld it as a whole item. Mechanical processing can also achieve this result, but the cost is far higher than the above mentioned.

Since laser welding robot often adopts fiber laser as the laser source, it is easy to achieve multi-station and multi-light path processing. This kind of processing method can greatly improve the production efficiency. Laser welding robot is far superior than CO2 laser machine. That is because CO2 laser machine is difficult to achieve multi-light paths. For the time being, there are already many cases about laser welding robot replacing CO2 laser machine in the automation industry with the welding efficiency increasing by more than 30%.

Of course, there will be some challenges in metal welding, for example, the shape of the work piece will become more and more complicated; the customized welding order will increase; the welding quality is becoming more and more demanding... But with laser welding robot, these challenges can all be solved very easily.

As mentioned before, laser welding robot is often equipped with fiber laser. Just like any other laser machines that is supported by fiber laser, laser welding robot also requires a laser chiller system to keep it running normally. And S&A Teyu can help with the CWFL series chillers. CWFL series laser welding chillers are supported by a dual temperature control system applicable to cool the fiber laser source and the welding head at the same time. The temperature stability ranges from ±0.3℃ to ±1℃. Find out more detailed information about CWFL series laser welding robot chillers at https://www.teyuchiller.com/fiber-laser-chillers_c2
