What does a welding inspector primarily look for in a completed SMAW weld?

A welding inspector primarily evaluates the quality and integrity of the welds produced. In the context of Shielded Metal Arc Welding (SMAW), the inspector focuses on several critical factors, including adequate penetration, which ensures that the weld has penetrated sufficiently into the base material to create a strong bond. Additionally, bead consistency is another vital aspect, as a uniform bead indicates proper technique and control during the welding process. Lastly, an absence of defects is crucial, as any porosity, cracks, or other irregularities could compromise the weld's strength and durability.

These criteria are essential for ensuring that the welded joint meets the required standards for performance and safety. While bead color and length can provide visual indicators of quality, they do not encompass the overall structural integrity that the inspector must assess. Similarly, inspecting a welder's personal protective equipment or training certificates, while important for safety and qualification, does not directly relate to the quality of the weld itself. Thus, focusing on penetration, bead consistency, and defect absence provides a comprehensive overview required for effective evaluation of the weld's quality.
