Eddy Current Array (ECA) technology has become a key enabler for rapid, high-resolution inspection of welds across a variety of conductive materials, offering superior sensitivity to surface-breaking flaws and submillimeter surface defects. Building on this foundation, the development of orbital weld probes has extended ECA’s application to high-precision inspection of tube and pipe welds in aviation and aerospace systems.
In aerospace applications, orbital welds in critical tubing systems, such as fuel lines and hydraulics circuits, demand high-reliability inspection techniques capable of identifying surface-breaking defects that could compromise structural integrity or system performance. Traditional methods like dye penetrant and radiographic testing often fall short in terms of speed, repeatability particularly in high-density assemblies and non-ferromagnetic alloys.
Eddy Current Array (ECA) technology offers a field-proven solution for orbital weld inspection, combining high sensitivity to surface flaws with rapid and full-circumference coverage in a single scan. By utilizing multiplexed sensor arrays, ECA generates high-resolution electromagnetic responses that reveal cracking, porosity, and other discontinuities with precision. This capability is particularly effective in inspecting thin-walled tubing and components with restricted external access, common in aerospace systems, where traditional methods are limited. Its capacity to adapt and deliver consistent, high-quality data in real time positions ECA as the standard for modern weld inspection.
These advancements collectively redefine the benchmark for weld inspection, enhancing reliability, accelerating inspection cycles, and improving data quality while reducing operational downtime.
