In terms of welding safety, arc blow usually requires what level of attention?

Arc blow is a phenomenon in welding that occurs when the electric arc is deflected from its intended path due to magnetic fields, which can result in an unstable arc and poor weld quality. In terms of welding safety, arc blow can lead to increased spatter, a rough weld bead, and even develop into a more serious issue if not addressed promptly.

Immediate corrective action is necessary because prolonged arc blow can create safety hazards, including weld defects and increased risk of arc strikes to the welder. Addressing the issue as soon as it is identified helps to ensure safe and effective welding operations, maintains the integrity of the weld, and protects the welder and their environment from potential dangers.

Taking minimal intervention, performing routine maintenance checks, or relying on single point observation may not sufficiently address the underlying issues caused by arc blow. These approaches could allow problems to persist, leading to more severe complications that may affect both the quality of workmanship and the overall safety of the welding process.
