In the view of the TURIN welding robot team, setting welding parameters can help the welding robot improve accurate welding, and the welding gun can accurately find the welding position and put down the appropriate welding material for filling. Welding robots can improve welding efficiency while ensuring quality and completing welding work. Welding parameters include welding current, welding voltage, movement speed of the manipulator, movement accuracy, position and posture of the welding torch, etc. The operator can set via the indicator.
How to adjust the welding parameters of the welding robot:
1. Adjust the welding current
The welding current is the circuit current of the electrode and wire. When setting the welding current, it is necessary to refer to the specifications of the welding seam and the penetration depth. If the welding current is too large or too small, the welding quality will be affected. If the welding current is too small, it is not easy to bend, and the welding process The medium arc is unstable, but welding defects, excessive welding current, large welding depth, and wide welding will result in waste of welding spot spatter. On the premise of adjusting the welding current, the welding current can be appropriately increased to improve the welding efficiency.
2. Adjustment of welding voltage
Adjusting the welding voltage needs to match the current. When the welding current is low and the voltage is high, the welding robot is prone to spatter the welding spot and deform the workpiece during the welding process. Only when the voltage is low, the welding process will become relatively stable, so that the welding seam can be formed well, which is beneficial for enterprises to use welding robots for sheet welding.
3. Movement speed of the robotic arm
The motion control system of the welding robot is mainly composed of auxiliary modules such as program interpreter, motion plug, servo driver, etc., to ensure the welding accuracy of the welding robot during the movement process. The setting of the movement speed can be carried out in the control system and can be combined with the welding specifications of the workpiece to be welded.
4. Select the appropriate electrode to improve the welding quality
The welding robot uses a thinner electrode in welding, and a smaller welding current should be selected; a thicker diameter electrode should choose a larger welding current to provide the heat required to melt the electrode.
In addition, the adjustment of welding parameters should pay attention to the following points:
1. Matching of welding current, voltage and welding wire
Welding current is an important welding parameter for welding robots, and the welding current is usually set together with the welding voltage. Before the welding robot enters mass production, the welding current and voltage should be debugged. During short-circuit transition, the welding current increases, the welding voltage decreases, and the short-circuit current increases to a certain value, and thin welding wire can be used for welding; thick welding wire can be used for fine particle transition.
2. The voltage should not be too high
When the welding current is low and the voltage is high, the six-axis welding robot is prone to spatter and workpiece deformation during the welding process. Only when the voltage is low, the welding process becomes relatively stable, which can make the welding seam well formed, which is beneficial for enterprises to use welding robots for sheet welding.
3. Set the welding speed
The welding speed of the welding robot needs to match the speed of the enterprise production line. During the welding process, if the setting speed is too fast, it is easy to have welding defects, and if the speed is too slow, it is easy to slow down the production cycle. Therefore, the welding speed needs to be set according to the production line.
4. Welding gun pose
Faced with different welding seams, it is also necessary to adjust the position of the welding torch, which is related to the welding flexibility of the robotic arm.
Finally: the setting of welding parameters cannot be realized in one step. The setting of welding parameters also has certain requirements on the skill of the operator. Operators need to be able to skillfully set welding parameters and adjust welding parameters according to the actual welding quality. With two to three adjustments, stability in mass production can be achieved. By setting the welding parameters, the user can ensure the welding quality while realizing the smooth operation of the welding robot and help improve the user's production efficiency.
