2008年5月我们在为一批10个焊工考试时做了RT和BENT TEST,RT全部合格,10个焊工却只能有3个能通过弯曲试验。 这就说明焊工很难操作,而射线却很容易漏检。 焊工考核的详细资料如下: Welding process:(135) MAG welding Product Type:(P) Plate Type of Weld:(BW) Butt Weld Material Group:W01 Welding Consumable...

Non-destructive confirmation of seamless welding is of critical importance in most applications and digital industrial radiography (DIR) is often the method of choice for internal flaw detection. DIR images often suffer from fogginess, limiting the inspection of flawed regions in online and ...

(Carbon dioxide gas shielded welding,alloyed welding wire).submerged arc welding, VSR treatment after weldment. The rugged design of press frames reduces the deflection of platens to practically zero at full load molding. Resulting in uniform molding...
The X-ray NDT equipment is used to show the internal discontinuity or faults of materials, products or welding from a radiographic image on a film, according to the principle of the different absorption of the X-ray for different material depending on the different thickness of the materials. ...
2013的注解c中明文规定UT可以取代RT,而且在这种情况下可以免去弯曲试验BENT TEST。无论新旧版本只做RT的话,都是不能免去弯曲试验BENT TEST的,为什么呢?有解释,是因为这种焊接型式(131、135、138和311)容易产生FUSION TYPE DEFECT(熔合性缺陷),例如:CLD LAP(冷焊)。射线检测RT是不能有效检测出来的。
Metal wires should traverse across the weld and are perpendicular to the welding direction. Wires of smaller diameters are placed on the outer side. When it is impossible to place the indictor at the same side with the radiation source, the indictor may be placed on the weldment surface at ...
We own 5 designers from rendering design to final installation drawings, and there are professional workers of cutting, welding, grinding, spraying, and assembly in workshop. Our factory has introduced full range of advanced machines such as raw materials handling machine, high...
