The application of welding robots not only combines the advantages of high and stable efficiency, but also has excellent flexibility, ensuring stable operations even in complex environments.
A complete welding robot system includes the robot body, robotic welding equipment, welding positioner, control system and other auxiliary equipment.
How is the stability and welding quality of welding robots? According to the welding experts I consulted, the main factor that affects the quality of robotic welding is, in fact, the technical issue of the robot operator.
There is a layer of yellow coating on the weld surface after manual welding, but using a welding robot can avoid such problems and ensure the quality of welding.
First, we should know that this yellow substance is actually impurities in the welding wire and welding base material, mainly caused by the high-temperature oxidation of silicon and manganese elements during the welding process, which chemically reacts with CO2 gas on the shield and decomposes to form silicon oxide and manganese oxide. The oxides are somewhat similar to the slag formed during manual stick welding.
Although these phenomena are also produced by the use of welding robots, these oxides do not negatively affect the quality of the weld, except for a slight appearance, and can be easily removed with a brush.
There are some silicon and manganese elements in the metal elements of the solder base material, and this phenomenon is objectively present.
If you want to reduce these oxides, you can use wires with fewer silicon and manganese elements and use less carbon dioxide shielding gas. When using gas mixture, there will be less oxide welding and much less yellow staining.
The most important thing in the welding production process is to ensure welding quality. Welding quality directly affects the usability and safety of the welding structure.
There are many factors that affect the quality of welding, among which the biggest are welding defects and the selection of welding parameters.
Welders who are involved in welding work for a short period of time cannot deal well with welding problems, leading to the inclusion of internal slag, porosity, undercuts and welding nodules and other welding defects.
In selecting welding process parameters, each welder will adjust the welding current, welding voltage, type and polarity of welding power source, welding speed and diameter and extension length of welding wire according to his actual experience .
Choosing the wrong welding parameters due to insufficient experience can lead to a decline in welding quality.
Many welders, although they pay close attention to the results of non-destructive testing, often neglect the appearance quality of the weld, leading to unqualified weld appearance and rework, thereby reducing work productivity.
The advantage of using welding robots lies in their stable operation, while ensuring that welding quality meets or exceeds expectations. Adjusting welding process parameters with robots is simple and only requires direct configuration.
Furthermore, the robots have built-in formulas to automatically adjust current and voltage. During robotic welding, the welding parameters for each weld are constant, minimizing the influence of human factors on weld quality and reducing technical demands on robotic operators.
To make the operation of welding robots more flexible and intelligent, we recommend users to equip them with a seam tracking system. This system automatically detects and adjusts the position of the welding torch during the welding process, ensuring that it always follows the welding position.
Maintains a constant distance between the torch and the workpiece, thus ensuring welding quality, improving welding efficiency and reducing labor intensity.
This system can solve welding quality problems caused by thermal distortion and inconsistencies in the workpiece. Additionally, it can free welders from harsh environments, reducing the risk of physical injury.
