Application:
The portable weld seam tester is designed for the detection of defects with high precision and speed. After detection, the unit evaluates the defects:
1. Testing aircraft components such as the alloy structure, framework, blades, wheel hub and undercarriage
2. Crack detection of the inner surfaces of aircraft rivets and screw bolt holes with or without fasteners
3. Testing metal components for a variety of industrial applications including nuclear power equipment, aerospace machinery, train engines, electric power equipment, petrochemical machines, and automobiles.

Features：
The ETP0202 portable weld seam tester is a highly valuable testing unit that makes use of electromagnetism theory to detect defects in metal components. It was developed by COBE engineers to solve the problems of traditional ultrasonic testing units that were too complicated and unreliable. The new testing unit is suitable for rapid detection and does not require the test surface to be extensively cleaned to achieve accurate results. The high sensitivity and precision of the seam tester is unrivaled and it can be equipped with intelligent detector units to improve detection efficiency and speed.
The technological parameters of the portable weld seam tester such as the frequency, gain and phase position should be pre-determined by the operator according to the task at hand. During the test, you can carry out detection at any time by choosing the corresponding technological parameters.
