At a food-grade stainless line, inspector Morgan is reviewing weld W-2204 on day 14 of a CWI practice rotation. The packet references AWS Part B inspection tool kit, drawing revision R6, and a WPS that was issued before the night shift changed fit-up practice. Ambient temperature is 83 deg F, the crew is behind schedule, and the foreman says the same condition passed on a different job. Part B is open book and practical, so the candidate must use the BOS, exhibits, specimens, and tools. The issue in front of you is unlisted backing change. Which response best matches CWI exam practice and the applicable inspection logic?
At a pressure-piping module shop, inspector Patel is reviewing weld W-2191 on day 25 of a CWI practice rotation. The packet references AWS Part B weld replica set, drawing revision R5, and a WPS that was issued before the night shift changed fit-up practice. Ambient temperature is 76 deg F, the crew is behind schedule, and the foreman says the same condition passed on a different job. Part B is open book and practical, so the candidate must use the BOS, exhibits, specimens, and tools. The issue in front of you is missed start crater in a multi-pass weld. Which response best matches CWI exam practice and the applicable inspection logic?
At a structural steel fabricator, inspector Nguyen is reviewing weld W-2120 on day 26 of a CWI practice rotation. The packet references AWS B1.10 NDE guidance, drawing revision R6, and a WPS that was issued before the night shift changed fit-up practice. Ambient temperature is 83 deg F, the crew is behind schedule, and the foreman says the same condition passed on a different job. Part A is closed book, so the candidate must apply fundamentals without looking up a table. The issue in front of you is crater cracks. Which response best matches CWI exam practice and the applicable inspection logic?
At a pressure-piping module shop, inspector Patel is reviewing weld W-2215 on day 25 of a CWI practice rotation. The packet references AWS Part B weld replica set, drawing revision R5, and a WPS that was issued before the night shift changed fit-up practice. Ambient temperature is 76 deg F, the crew is behind schedule, and the foreman says the same condition passed on a different job. Part B is open book and practical, so the candidate must use the BOS, exhibits, specimens, and tools. The issue in front of you is revision mismatch. Which response best matches CWI exam practice and the applicable inspection logic?
Bridge Girder Inspection During the fabrication of a steel bridge girder, a CWI is inspecting a full penetration groove weld in a butt joint between two 1-inch thick A36 plates. The weld was made using the Shielded Metal Arc Welding (SMAW) process. The visual inspection reveals a smooth, uniform weld face that is slightly recessed below the surface of the base metal.
Which of the following terms BEST describes the observed weld face contour?
La respuesta correcta es B, Concavidad. La concavidad se define como una superficie de soldadura que se encuentra debajo de la superficie del metal base, formando una depresión poco profunda. Esto coincide directamente con la descripción del escenario de una 'superficie de soldadura lisa y uniforme que está ligeramente hundida'. En las soldaduras de ranura, algunos códigos permiten una cantidad limitada de concavidad, siempre y cuando no reduzca la garganta efectiva por debajo del mínimo especificado. La opción A, Convexidad, describe la condición opuesta en la que la superficie de soldadura sobresale por encima del metal base. La opción C, Subexplotación, es una ranura o cráter en el borde de la soldadura donde el metal base se ha derretido pero no se ha llenado adecuadamente, lo que es una discontinuidad y no una descripción simple de la forma de la superficie. La opción D, Superposición, es la protrusión del metal de soldadura más allá del borde de la soldadura sobre el metal base no fundido, creando una arista aguda y a menudo susceptible a la grieta. Comprender estas características visuales es fundamental para la evaluación inicial de un inspector de soldadura certificado antes de proceder a métodos de inspección más detallados.
