Non-Destructive Testing (NDT) is an indispensable quality assurance technology in modern industry. It enables the detection of internal defects, structures, and property conditions of materials by utilizing characteristics such as acoustic, optical, magnetic, and electrical properties—all without damaging or affecting the performance of the tested object.

Compared to destructive testing, NDT has the following characteristics:

First, it is non-destructive, as it does not impair the performance of the test object.
Second, it is comprehensive. Since the testing is non-destructive, it allows for 100% full inspection of the test object when necessary, which is impossible with destructive testing.
Third, it is full-process applicable. Destructive testing is generally only suitable for raw materials, such as tensile, compression, and bending tests commonly used in mechanical engineering. Destructive testing is conducted only on raw materials for manufacturing. For finished products and in-service equipment, destructive testing cannot be performed unless they are no longer intended for use. In contrast, NDT does not damage the test object’s performance, making it suitable for full-process testing, from raw materials and intermediate manufacturing stages to final products, as well as for in-service equipment.

Among the many manufacturers of non-destructive testing equipment, Dandong Tongda Technology Co., Ltd. has developed a variety of NDT instruments that approach or achieve internationally advanced levels, thanks to its solid technical expertise and innovative capabilities.

Technical Features: Portability, Safety, and Intelligence
Tongda Technology's NDT Portable X-ray Welding Testing Machine exhibit several outstanding features. Their X-ray generators adopt an anode grounding and fan-forced cooling design, making them compact, lightweight, portable, and easy to operate.

In terms of safety performance, the equipment is equipped with a delayed exposure function, effectively ensuring operator safety. The devices operate on a 1:1 work-rest cycle, with a rational duty cycle design that ensures detection efficiency while extending the equipment’s service life.

The company’s products incorporate Programmable Logic Controller (PLC) technology and a modular design concept, enhancing automation, improving anti-interference capabilities, and ensuring an extremely low failure rate.

Application Areas: Wide Adoption Across Multiple Industries
Tongda Technology's NDT Portable X-ray Welding Testing Machine are suitable for various industrial sectors, including national defense, shipbuilding, petroleum, chemicals, machinery, aerospace, and construction.

These instruments are used to inspect the welding quality of materials and components such as ship hulls, pipelines, high-pressure vessels, boilers, aircraft, vehicles, and bridges, as well as the internal quality of various lightweight metals, rubber, ceramics, and other materials.
