Which of the following is a method to prevent weld defects?

Ensuring proper electrode angle and movement is a critical factor in preventing weld defects. The angle at which the electrode is held and the technique employed during the welding process significantly influence bead shape, penetration, and overall weld quality. A proper angle allows for better flow of molten metal, promotes uniform heat distribution, and minimizes the risk of defects such as incomplete fusion, undercut, or excessive spatter.

Additionally, maintaining consistent movement of the electrode ensures even deposition of filler material, which contributes to the integrity and strength of the weld. This technique allows the welder to control the heat input and manage the puddle more effectively, leading to a sound and defect-free weld.

Other methods mentioned may contribute to challenges rather than solutions in welding practices. For example, using high heat at all times can lead to burning through materials or distortion, while welding in enclosed spaces can often introduce issues like inadequate ventilation, leading to increased susceptibility to defects. Similarly, maximizing the distance between the workspace and the power source can result in loss of heat and inadequate arc stability, creating additional problems for the welding integrity.
