1. The weld bead and welding trajectory cannot be corrected
First of all, in teach-in mode, the empty walk procedure ensures that the welding orientation is correct. Secondly, consider that there is a problem when soldering*** is searching. At this time, it is necessary to consider the way the welding robot finds the weld bead (arc or laser) to set, and after analyzing whether the TCP (welding *** center point orientation) is accurate and adjusting. If this situation occurs frequently, it is necessary to check the zero position of each axis of the robot, and re-calibrate it for correction.
2. There are a lot of undercut problems
Consider whether the welding parameters are not properly selected, the current is too large, the voltage is too large, the welding posture is not conducive to welding, and whether the welding orientation is limited, and adjust it appropriately.
3. There is a problem of dense pores
It may be that the gas is poorly maintained, the welding surface of the workpiece is not clean, or the maintenance gas is not boring, and it can be dealt with by adjusting accordingly.
4. Excessive splash problem
It may be due to improper selection of welding parameters, gas composition or too long extension length of the welding wire, you can properly adjust the size of the machine power to change the welding parameters, adjust the gas ratio instrument to adjust the gas mixture share, and adjust the relative orientation of the welding machine and the workpiece.
5. The problem of an arc pit is formed after cooling at the end of the weld
The pit function can be added to the working step when programmable, and it can be filled.
6. No arc starting
It may be due to the fact that the welding wire does not touch the workpiece or the process parameters are too small, the wire can be fed manually, the interval between the weld and the weld can be adjusted, or the process parameters can be adjusted appropriately.
7. Poor weld forming
It may be due to the uneven installation void of the weldment, the welding swing amplitude is too high or too low, the current selection is not suitable, and the welding speed does not match the parameters.

The way to reduce spatter – OTC welder
1. Adjust the arc voltage
If the settings are incorrect, the voltage setting will significantly add to the spatter. The low voltage setting can cause spatter as the wire is repeatedly short-circuited in the weld pool, resulting in a small burst at the wire tip.
This short circuit is normal for short arc MIG welding, but ...

The type of control of the robot - OTC robot
1. The type of robot control can be divided into open-loop control and closed-loop control according to whether there is a reaction or not, during which open-loop control is generally considered to be more accurate, but the requirements are more chaotic. Generally speaking, if we want to achieve open-loop accurate manipulation, we need to know the accurate model of the controlled object ...

OTC Odichi welding machine to reduce spatter method
Splash issues
Because metal is thrown from the weld point to adjacent surfaces, spatter reduces power and adds expense to the installation line. After the welding is completed, the welder needs to sort out the weld, and the rest of the data is wasted.
Many welders think it's part of welding. Many people learn ...

OTC robot contacts need to be replaced
Contacts are one of the items that often replace welding materials. During this time, the contact fixes the direction of the wire, and since the instantaneous current that moves when the arc is closed after welding is too simple to melt the contact outlet, it must have a role. The wire and contacts have been welded together, so that the welding can no longer be performed ...
