Testermeter-llW2 test block,V2 test block,horn test block,international standard test block
| The standard test blockis the foundation of faw detection, based on the eariest "Dutch test blodk", After decades of development. domestic industries such as powerpetroleum, shipbulding, stel structures,and cranes have their ownindustry standards forfaw detection according to their neds, and corresponding standard test blocks havebeen specied. 0ur company has been inwowed inthe draling of national testing standards sincethe 1980sand has pariipated inthe revsion of over 20 testing standards.in2013, participated in the revision ofthe GB/T11345-2013 "Ultrasonic esting Technology, Testing Levels and Evaluation for Non destructive Testing of Wwelds" standard, anddesigned and produced coresponding standard flaw detection test blocks according to the standard regulations. At the same time, l also participated in the writing anddiscusion ofthe ultrasonic part of NBT 47013 1/T4730 "Non destructive Testing of pressure Equipment, provding a large number of expeimental test blocks for the expertgroup and collecting a lot of data in coniunction with experiments.providing important basis for standard revision, Our company has extensive exchanges with colleagues in theinternational industry and has received visits from friendsthe Mniec，Russia,Indla.Japan,South korea.ano othercountries multiple times.Our productsGermanv.Knacon.are exported to the United States, Canada, Russia, India, South Korea, Japan, Germany, France, and other countries. |
lW2 test block
| IW2 test block (v-2 test block is a standard test block aproved by the international Welding Society. Compared with l test blocks, V-2 (DIN54122) has theadvantages of being lightweight, easy to carry, and particularly suitable for on-site use. As shown in figures 1-2. |
Key points for use:
(1) Measure the incident point and sensitivity margin of the oblique probe using a circular reflector with a radius of R50mm; |
2) Utiize o The refection surface of the 5-way hole can be used to measure the refractive range ofthe oblique probe, which is 45"-65" and 65"-75", respectively1 |
3) By utlzing multiple longitudinal wave refections from a botom surface with a thicknes of 12.5mm, the horizontal and vertical linearty of the flaw detector carbe measured; |
| (4) Use the two curved surfaces R25 and R50 to calibrate the timeline and zero point. |
