In welding, cutting, and brazing operations, common hazards include burns from hot metal, the risk of electrical shock, and exposure to flying sparks and molten metal. These hazards arise from the very nature of these processes. Burns can result from contact with hot surfaces or materials, while electrical shock is a significant concern given the high current involved in these operations. Additionally, flying sparks and molten metal pose a direct risk to the skin and eyes, making personal protective equipment essential.

Conversely, asphyxiation is generally not a typical hazard specific to welding, cutting, and brazing, except in certain unique circumstances or environments. The primary concerns leading to asphyxiation tend to be related to confined spaces or inadequate ventilation where toxic fumes from materials being welded or cut could accumulate. However, in standard welding operations, asphyxiation is not considered a direct hazard like the other options listed. Thus, it correctly identifies that asphyxiation is less commonly associated with these tasks compared to the more immediate hazards that welders face.
