| Small diameter pipe butt weld through the thickness of the discussion according to
Complex. In order to give a simple, easy to practical application through the thickness according to formula to the above formula gives the small-diameter pipe butt weld through the thickness according to the basis of linear regression. The data in Table 2, the linear regression (for 3 times through the use of a number of photos not included in Table 2 data), you can get the following NDT Vol 30, 8 simple through the small diameter tube butt weld According to the calculation of the thickness of type (type with D, in millimeters, and the result units are in millimeters). 2 according to the situation through the TA2-2.71T + T / D) a 0.37 (  3 times according to circumstances through the TA3-2.24T + T / D) a 1.94 (9) their correlation coefficient r 0.9998 a 0.9968r a visible,moncler günstig, established by the approximate formula can be applied to the actual situation. Table 2 shows the last column by ( and (9) The calculation of value. Of course, if the use of more data, you can create with other factors according to the approximate thickness of transparent formula,ugg italia, and you can get a better relationship with the calculation formula, but their basic form will remain unchanged. Approximate formula given here,Moncler jacken, one line with the actual requirements through the processing according to parameters, and second, with a clear basis for the three is in line with national standards from the late 20th century, clearly defined 80 requirements,air jordans, four is a simple form. So that, the results have been basically solved through small-diameter pipe butt weld according to the determination of thickness, which is solved through small-diameter pipe butt weld accurately determined according to parameters of the problem. Based on this result,stivali ugg, can no longer use the \It should be noted that the approximate formula given, when applied to the actual inspection work, can be combined with practical experience modify the numerical factors, and probably more realistic given formula. But the formula does not need to modify the basic form. References: E1] Zhou Dickson.

Vice Chairman of China Society for Nondestructive Testing of Jilin Shen Gong fields and the Secretary-General Xu Yongchang, electromagnetic (eddy current) i Professional Committee Linjun Ming and from all colleges and universities, research institutes and representatives of more than 47 industries participated in the meeting. The meeting aims to exchange the palm of China in recent years, the electromagnetic (eddy current) without the latest i loss detection theory, the latest technology and the application process! In practical work and results achieved and gained valuable experience, {i study of the electromagnetic (eddy current ) technology status, direction and what if i take the road of independent innovation with Chinese characteristics. Annual meeting received hairpin: * - Zan: * - Zan Zan Qi :·-:·-:·-: * - Lee held more than 50 papers, covering magnetic memory, eddy current, magnetic flux leakage and other aspects of the new Technology and application of the results. One, the magnetic memory of the paper 19, Eddy 22, magnetic flux leakage, and other 8 6, a detailed summary of papers published in a collection, Proceedings CD-ROM 1. During the meeting, representatives painstaking, careful and comprehensive for each paper is discussed, warm atmosphere of the meeting, a heated debate. Through the exchange, learn, gain a larger majority of participants feel. The success of this meeting was held, once again reflects our electromagnetic (eddy current) non-destructive testing technology, the rapid development of new theories, new technologies, new methods are emerging, showing the \. Let us join hands and work together for the 2008 will be held in China to add luster to the World Conference of Nondestructive Testing.
