Arc welding robots are industrial robots used for automatic arc welding, and their composition and principles are basically the same as spot welding robots. However, problems such as welding arc breakage often occur during the use of arc welding robots. So, regarding this issue, an analysis has been conducted on the causes of welding arc breaks, hoping to be shared with everyone.
Improper program settings. In the process of automated welding, arc welding robots must perform precise operations according to preset programs. If there are errors in the program, such as mismatched arc start and stop instructions, or unreasonable welding path planning, it may lead to arc breakage. Therefore, during the debugging phase, it is necessary to carefully inspect the welding program to ensure its accuracy and correctness.
The surface condition of the welded parts is poor. If there are oil stains, impurities or hanging objects on the surface of the welded parts, these will affect the stability of the arc and the welding quality, thereby increasing the risk of arc breakage. Therefore, before welding, the welded parts must be thoroughly cleaned and treated.
Wear and tear of electrodes. As the welding time increases, the electrode will gradually wear out, leading to a decrease in arc energy and instability of the arc. When the electrode wears to a certain extent, arc breaking may occur. Therefore, regular inspection of electrode wear and timely replacement of severely worn electrodes are effective measures to prevent arc breakage.
The welding parameter settings are unreasonable. The setting of parameters such as current and voltage must be adjusted reasonably according to the actual thickness and material of the workpiece. If the parameters are set improperly, it will not only affect the welding quality, but may also lead to the occurrence of arc breakage.
Based on the above understanding, the reasons for arc breaking in arc welding robots are multifaceted, including improper program settings, poor surface condition of welded parts, electrode wear, and unreasonable welding parameter settings. In order to effectively solve the problem of arc interruption, it is necessary to start from multiple aspects.
