Identify a factor that can affect the quality of a weld bead.

The speed and angle of the welding torch are critical factors affecting the quality of a weld bead. When the torch is moved too quickly, the heat may not penetrate the base material adequately, resulting in a weak weld. Conversely, moving too slowly can lead to excessive heat, causing distortion or burn-through, which compromises the integrity of the weld. Furthermore, the angle at which the torch is held influences the heat distribution and can affect fusion between the base materials and filler.

Ensuring the correct speed and angle allows for proper melting of the base and filler materials, ensuring good penetration and a uniform bead appearance which contributes to the overall strength and quality of the weld. Thus, mastering the speed and angle is essential for a successful welding outcome.
