As we all know, there are many enterprises applying welding robots in the welding industry. That's because robots not only have high production efficiency, but also have many advantages. This is also an important reason why enterprises use welding robots to replace traditional handwork. First of all, we should know that this yellow thing is actually the impurity in the welding wire and welding base metal. The main reason is that the high-temperature oxidation of silicon manganese element reacts with the CO2 in the maintenance gas during the welding process to differentiate into oxides formed by silicon oxide and manganese oxide, which is a little similar to the welding slag of manual welding rod.

Although these phenomena will occur even if welding robot is used, these oxides will not cause any adverse effects on the welding quality except for the appearance defects, which can be easily removed by brush. If you want to reduce these oxides, you can choose the welding wire with less silicon and manganese elements, and replace the maintenance Gas with the mixture gas with less CO2 content. The oxide content will be less and the yellow spot will be much less.

Welding robot not only has the advantages of high efficiency and efficiency and stability, but also has good flexibility, which can ensure its stable operation even in complex environment. This is inseparable from the composition of the welding robot, including the main body of the welding robot, welding power supply, one-dimensional heavy sliding table, robot l-arm, cleaning gun and wire cutting station, control system and other equipment.

So how about the welding quality of the welding robot? If we say that after manual welding, the weld surface will show a piece of yellow covering, then the welding robot only needs to pay more attention to avoid the occurrence of similar problems and ensure that the welding quality can be qualified.

Considering that the robot has to meet the load ability, it can send the welding tongs to the spatial orientation with a large acceleration, and the heavy-duty robot with 100-150kg load is generally selected. In order to get used to the requirement of short distance and rapid displacement of welding tongs during continuous spot welding. The new heavy-duty robot adds the ability to finish 50 displacement in 0.3. This puts forward higher requirements for the performance of the motor, the operation speed and algorithm of the microcomputer.

How much load the welding robot needs depends on the type of welding tongs used. With the welding tongs separated from the transformer, the robot with a load of 30-45 kg meets the requirements. However, on the one hand, due to the long secondary cable, the power loss is large, which is not conducive to the robot to extend the welding clamp into the workpiece for welding; on the other hand, the cable is constantly swaying with the movement of the robot, and the cable damage is fast. Therefore, the use of integrated welding tongs is gradually increasing. The weight of the welding tongs together with the transformer is about 70kg.
