Arc breakage during welding is one of the common problems, which is usually caused by low current during welding, poor quality of welding rods, and unstable performance of welding machines.
First of all, to solve the problem of welding arc breakage, you need to start with the welding current. Welding current is one of the key factors affecting welding quality, if the current is too low, it will lead to problems such as incomplete welds and easy cracking, which will cause arc breakage. Therefore, in the welding process, it is necessary to select the appropriate welding current according to the thickness and material of the plate to ensure the quality and stability of the weld.
Secondly, the quality of the welding rod is also an important factor affecting the arc breakage of welding. If the quality of the electrode is not good, it contains too many impurities and pores, which will lead to the phenomenon of arc breaking in the welding process. Therefore, when choosing welding rods, you need to choose regular brands and reliable quality products, and try to avoid using inferior welding rods.
In addition, the performance of the welding machine is also one of the important factors affecting the arc breakage of welding. If the performance of the welding machine is unstable, it will lead to problems such as current fluctuations and unstable welding arcs during the welding process, which will cause arc breakage. Therefore, when choosing a welding machine, it is necessary to choose products with stable performance and reliable quality, and at the same time, it is also necessary to regularly maintain and maintain the welding machine to ensure the normal operation of the welding machine.
In addition to the above aspects, there are some other measures that can help solve the problem of welding arc breakage. For example, preheating the weldment before welding can reduce the risk of cracking the weld and thus the occurrence of arc breakage. In addition, it is necessary to pay attention to the operation posture and skills during the welding process, and maintain the correct operation posture and welding speed, which can reduce the heat loss and airflow influence in the welding process, thereby reducing the occurrence of arc breakage.
In short, solving the problem of arc breaking in the welding process needs to start from many aspects, including choosing the right welding current, using reliable quality electrodes and welding machines, and paying attention to operation skills and posture. Through the comprehensive application of these measures, the occurrence of welding arc breakage can be effectively reduced, and the welding quality and stability can be improved. At the same time, it is also necessary to strengthen the training and management of welding technology, improve the skill level and quality awareness of welding workers, and avoid the occurrence of welding arc breakage from the source.
In addition to the above-mentioned measures, there are some other workarounds that can be tried. For example, auxiliary tools such as splash inhibitors and baffles can be used during the welding process to reduce welding spatter and protect the quality of the weldFor some special materials and structures, special welding processes and methods can be adopted, such as the use of multi-channel multi-layer welding technology, symmetrical welding, etc.;For some large structures or long-distance welds, segmented welding technology or mobile welding equipment can be used. These methods can solve the problem of arc breakage in the welding process to a certain extent, and improve the welding quality and stability.
In addition, for some arc breaking problems that are difficult to solve, other welding methods or equipment can be considered as alternatives. For example, high-energy beam welding technologies such as laser welding and electron beam welding can be adopted, which have the advantages of high precision, high efficiency and high reliability, and can effectively solve the arc breaking problem that is difficult to solve by traditional welding methods.
