Welding robots may encounter some malfunctions:

Porous issues have arisen (possibly due to inadequate gas protection, excessively thick undercoat on the workpiece, or insufficiently dry protective gas; making the corresponding adjustments should resolve the issue).

2. Welding offset issues have arisen (which may be due to incorrect welding positions or issues with the welding gun's search for the correct spot. In such cases, consider whether the TCP (Tool Center Point) is accurately positioned and make necessary adjustments. If this issue occurs frequently, check the zero positions of the robot's axes and recalibrate them for correction.)

3. A problem arises where the weld bead ends, forming a crater after cooling (this can be addressed by adding a function for filling the crater during the programmable step).

4. Excessive splatter issues (may be due to incorrect welding parameter selection, gas composition reasons, or excessively long wire extension length; adjusting the machine's power to change welding parameters, adjusting the gas mixture ratio with a gas blending instrument, and adjusting the relative position between the welding gun and the workpiece can be done appropriately).

5. Edge biting issue occurred (may be due to improper welding parameter selection, torch angle, or torch position; adjustments can be made accordingly)

Potential faults encountered by welding robots during the welding process:

(1) A collision occurred. It may be due to an assembly deviation of the workpiece or an inaccurate TCP of the welding gun. Check the assembly or adjust the welding gun's TCP.

Arc fault occurred, unable to strike an arc. This may be due to the wire not contacting the workpiece or the process parameters being too small. Manually feed the wire, adjust the distance between the welding gun and the weld, or properly adjust the process parameters.

(3) Protective Gas Monitoring and Alarm. Check the coolant or protective gas supply lines if there is a malfunction.
