About TIME Group Inc.
TIME Group Inc. was established in October 1984 by Mr. Peng Weimin and MadamWang Xiaolan, along with many scientific and technical personnel, one of the earliest established modern high-tech manufacturing enterprises in Beijing Zhongguancun area, the pioneer of the mechanical and electrical industry in China as well.
Time Group Inc. manufactured the first Leeb hardness tester in China. After over 30 years of unremitting efforts, TIME Group has now developed into a big high-tech industrial economic entity with several billion yuan of assets, 8 holding companies, more than 30 sales subsidiaries and offices, nearly 2000 staff. Our products are involved in testing instruments, welding equipments, testing machines, robots and other high-tech industries. TIME group also builds a state-level technology center and post-doctoral stations, showing our research and development capability.
Upholding “self-design, work together, create excellence” guidance, TIME Group will always deliver state-of-the-art quality products and technologies that meet and exceed our customers’ requirements in the modern material testing world.
for thickness testing, while angle beam utilizes a beam that is introduced into the specimen at some angle other than 90 degrees – for defect location. The choice between the two is made based on the orientation of the feature of interest so that the sound may produce the largest reflection from the feature and obstructions on the surface of the specimen that must be avoided.
Some of the most common Ultrasonic applications are:
Flaw detection (cracks, inclusions, porosity, delaminating etc.) Erosion/Corrosion thickness gauging Info from ultrasonic inspection can be presented in a number of formats: A-Scan displays the amount of received ultrasonic energy as a function of time Be-Scan displays a profile view (cross-sectional) of a specimen C-Scan displays a plan type view of the specimen and discontinuities Hybrid/Stitched displays a C-Scan plan view with A and/or B Scan views along with C-Scan views that have been woven together to illustrate a clearer picture of the damaged areas of a specimen. The stitched views are used for larger specimens and surface areas.
Some of the major advantages of ultrasonic testing are:
Detects surface and subsurface defects Depth of penetration vs. other test methods is superior Only single sided access is required with a pulse-echo technique High accuracy regarding estimating discontinuity size and shape Minimal specimen preparation is required Instantaneous results produced by using electronic equipment Detailed images can be produced with automated systems.
Major limitations of ultrasonic testing are:
Surface must be accessible. Skill training is more extensive than with some other methods for personnel. Normally requires couplant to promote sound transfer. Surface roughness, complex geometries, small parts or exceptionally thin materials are difficult to inspect. Coarse grained material ie. Cast iron is difficult to inspect due to low sound transmission and high signal noise. Linear defects oriented parallel to the sound beam go undetected. Reference standards are required for equipment calibration for each item teste
