Uneven weld beads are often a direct result of incorrect travel speed or an improper torch angle. When the welder moves too quickly, the heat does not penetrate the base material adequately, leading to a shallow or weak weld. Conversely, moving too slowly can cause excessive heat buildup, which may lead to distortion or burn-through.

Additionally, the angle at which the torch is held can significantly affect the profile of the weld bead. An improper angle may lead to uneven distribution of the heat and filler metal, causing irregularities in the bead’s shape and consistency. Achieving a smooth, uniform weld requires careful control of both travel speed and torch angle to maintain an even heat and proper fusion.

Other factors, such as excessive rod length or using the wrong type of filler metal, can influence the quality of the weld but are less directly related to the specific issue of achieving an even bead. Lack of protective gear is also a safety concern but does not impact the weld bead quality itself. Understanding these nuances in welding techniques is critical for producing high-quality welds.
