Weihua technical inspection and testing center

Weihua technical inspection and testing center

Weihua technical inspection and testing center was established in August, 2004, covers an area of more than 1000㎡. In July, 2007, we were formally recognized through China National Accreditation Service for Conformity Assessment. Inspection report within the scope of approval issued by our test center not only available in China, but also more than 90 countries in the world, to achieve mutual recognition. In March, 2009, we were appointed as the regular testing agency by Henan Entry-Exit Inspection and Quarantine Bureau. This not only improved our product quality control and testing level, but also strengthened our competitiveness in international trade. At the same time, authorized by Henan Entry-Exit Inspection and Quarantine Bureau, we have rights to test exported cranes and their parts from other manufacturers and trading companies. There are seven testing rooms in the center, named as physical testing room, metallographic analysis room, nondestructive testing room, measuring room, chemical testing room, crane testing room and electrical laboratory.

China National Accreditation Service for Conformity Assessment
Physical test: Testing room are allocated with CHT4106 type electro-hydraulic servo universal material testing machine with maximum load of 1000KN, WEW-300C type hydraulic universal material testing machine with maximum load of 300KN, JB-300B type impacting testing machine with maximum impacting power of 300J, Brinell hardness tester, Rockwell hardness tester, HT320 hardness tester. Special equipment are also allocated, such as surface grinding machine, universal tool milling machine, electric spark wire cutting machine, impact notch for broaching machine. It can carry out mechanical performance test like tension, compress, bending, cutting, impacting (low-temperature impacting), etc. and also surface rockwell hardness like foundry (iron, steel) hardness, alloy material hardness, plating coat, carburizing, non-ferrous metal, etc.
Measuring room is mainly in charge of transferring and tracing instruments' values. We are Henan Province A-grade qualified Measuring Company. By authorization, we can verify by ourself of length mearing tools. In 2009, we were awarded as Henan Province Advanced Measuring Company with main instruments like projection one meter measuring machine, universal tool microscope and other measuring standard.
Electrical laboratory: We have modern training and teaching equipment in the laboratory, including PLC control system, human interface system, AC variable frequency drive system, field bus system and varieties of industrial configuration software systems like PROFIBUS-DP,C-LINK, etc. They represent the most advanced automation and transmission platform nowadays, which will bear the function of training and technical research of electrical automation and transmission systems in the industry of lifting equipment.
Chemical Analysis: the most advanced instruments are equipped in the test room, such as HW-2000 type high-frequency infrared carbon and sulfur analyzer, HGA-3B Manganese silicon phosphorus microcomputer high speed analyzer, UV-4802 type and ultraviolet visible spectrophotometer. They can meet requirements of all kinds of steel alloy element analysis like C、S、Mn、P、Si、Cu、Ni、Cr、Mo、Ti, etc.

Metallographic Analysis: XJL-03 type metallographic microscope which can be enlarged 800 times is allocated to test metallographic structure in the low carbon steel, medium carbon steel, low alloy steel, foundry steel, weld technique, etc. and microstructure in the raw material (foundry iron, graphite form), etc.
Non-destructive test: there is two staff in non-destructive room with ultrasonic and ray Ⅲ grade qualification, others are all four Ⅱ grade. More than ten pieces of instruments are allocated in the room, namely, X-ray detector, multi-purpose magnetic detection machines, numerical ultrasonic flaw detector, etc. All kinds of non-destructive detection can be carried out here, such as crane main girder weld joint, cable drum, hook, steel plate, high-strength bolts, steel tube, small diameter tube and shafts, etc.
Welding procedure is an important measurement to guarantee weld quality. Through welding procedure evaluation, it can be tested whether the functional performance of welded joint meets design requirement and provide reliable basis for welding technology. We have solid technical strength and full tooling equipment so that we can carry out evaluation of welded joint and issue evaluation reports.
Crane testing: Crane testing room mainly equipped with whole crane testing counter, electric hoist testing counter, theodolite, photoelectric tachometer, sound level meter, dynamic resistance strain instrument , static resistance strain gauge, etc. Almost all kinds of test can be carried out, such as main girder camber, bending, vertical divergence between main girder and web plate, local plane, horizontal divergence of upper flange plate, trolley rail height difference, crane rail local plane, span deviation, bridge diagonal, trolley gauge limit deviation, rail lateral straightness, trolley wheel height difference, wheel parity error, radial run-out, motor insulation, static stiffness, static loading test, dynamic loading test and so on.
