Automatic welding equipment common welding defects and precautions
First, stomata. The application of automatic welding equipment in full position welding, the stoma is a more common problem, resulting in the problem for many reasons, such as welding consumables own reasons, improper operation, environmental reasons. In view of this, in order to effectively prevent this problem, the protection of gas should be strengthened during the welding, the welding temperature should not be too high, and the gas should be filled strictly according to the proportion and related requirements to ensure the filling purity meets the requirements. At the same time also pay attention to the environment around the welding site, if the wind speed on the construction site more than 8 meters per second, the use of windshield to implement protection, and the environment should not be excessive humidity. In addition, in order to ensure that the welding position to keep dry, you can use a ring flame heater or medium frequency induction heater to implement heating.
Second, not fused. In the welding, the problem of unmelting usually occurs in the vertical welding position. The reason of the problem is that the shape of the welding bead is not correct, the welding welding deviation from the welding seam or the width of the welding gun swinging is not reasonable. In view of this, in the welding process, the implementation of the weld grinding operations, should be polished as smooth. At the same time before welding, but also the wire should be carefully observed to see whether the swing width is correct. In addition, during the welding process, if deviation occurs between the welding pool and the weld bead center, adjustments should be made in a timely manner so as to avoid the problem of unmelted.
Precautions:
1, flexible and diverse manner of solder, while supporting spot welding and drag welding (pull welding), automatic welding equipment, all process parameters can be set by the customer to adapt to a variety of difficult solder jobs and micro-solder process, all the solder parameters can be accompanied by welding Point coordinates program to read and save, to achieve the flexibility of solder operations.
2, iron components can be any angle, any position adjustment, control the R-axis iron group, you can freely rotate 360 degrees, according to different pads and components are free to set the number of tin delivery, preheating time and soldering time, to achieve a plate A variety of solder joints of the complex welding process, to achieve diversification of solder operations.
3, 4-axis / 5-axis robot manipulator, automatic welding equipment all servo drive and advanced motion control algorithms, effectively improve the end of the campaign - tip positioning accuracy and repeatability, to achieve accurate positioning of any welding space in 3D space.
