Which welding technique is more likely to lead to overheating during operation?

The weave pattern technique is more likely to lead to overheating during operation due to the nature of the method itself. Weaving involves moving the welding torch or electrode back and forth across the workpiece while a continuous weld bead is being deposited. This lateral motion can create a wider heat-affected zone as the arc moves over a larger area, leading to a greater accumulation of heat in the material.

In this technique, the prolonged exposure of the base metal to the heat from the arc can result in elevated temperatures that might not dissipate quickly enough, which can cause warping, burn-through, or other thermal distortions in the material. In contrast, a stringer bead produces a narrow and more concentrated weld, which minimizes the heat input and reduces the risk of overheating. Fillet and spot welds generally involve shorter durations of heat application, also mitigating the chance of overheating.

Understanding the properties and heat dynamics involved in different welding techniques is crucial for preventing issues such as warping and structural failure in welded components.
