Chained welding defect
Aligned weld defect happens when several nearby irregularities together make an unacceptable condition. Needs full inspection and fix.
Physical-Chemical Mechanism of Action
A chain of welding defects occurs when several nearby irregularities such as pores, cracks, or uneven deformation act together. This combination can impair the overall component and lead to structural instability.
Metallurgical Relevance & Welding Risks
A chain of welding defects can cause significant loss of mechanical strength, especially when the irregularities are in critical load areas. This can lead to cracking and component failure, posing safety risks.
Shop Practice & Action Guidelines
To avoid chain welding defects, careful control of the welding process is essential. This includes adhering to process parameters such as temperature, voltage, and time, as well as using high-quality materials. If a chain defect is detected, comprehensive correction is required, often by cutting out or gouging the affected area and rewelding.
