Cable tray weld defects
Some of the most common types of cable tray failures include loosening, corrosion, cracking, grounding issues, and installation errors. These failures, whether isolated or interconnected, significantly impact the performance and safety of the cable tray system. Welding remains a core technique in sheet metal fabrication for joining metal components, but weld defects—caused by improper processes, material mismatches, or outdated equipment—still pose risks to structural integrity. Recognizing and addressing these failures early can prevent more severe issues. Every welder, welding inspector, and fabrication engineer must have a working knowledge of the eight.
