  • In addition to producing high quality radiographs, theradiographer must also be skilled inradiographic interpretation .Interpretation of radiographs takes place in three basic steps: (1) detection, (2)interpretation , and (3)evaluation . All of these steps make use of the radiographer'svisual

  • Welding processes can introduce contaminants and metallurgical defects into a component. Applied Technical Services offers NDT welding inspection on structures, both ferrous and non-ferrous, or components to detect surface and sub-surface defects and discontinuities. In order to meet quality and safety standards, welds are commonly required to withstand load and stress conditions.

  • As anyone in the fabricating and welding business knows, process and part inspection is a critical component of a successful business. Build and weld a poor part will simply guarantee failure. Today, welding associations, such as the Canadian Welding Bureau, offer certification courses to help welders learn the ins and outs of proper inspection processes, but before taking the course, you should

  • The procedure of Post Weld Heat Treatment projects is often recorded in a quality document beforehand. It lists the requirements that should be met for the relevant heat treatments and that will lead to a guaranteed result. Post Weld Heat Treatment (PWHT) is the international term for stress relief annealing: a heat treatment that is carried out – among other things – after welding work

  • Induction Heating The most common methods for achieving a more controlled preheat temperature are induction heating and electrical resistance heating. “The equipment used for induction is considerably more expensive than that used for electrical resistance heating,” said Fong. “However it does get your steel hotter quicker. It still offers you much more control than what you

  • The Vessel Pressure Testing article provides you with information about pressure vessel hydro-static testing requirements and related item in pressure vessel inspection. The requirements have been described based on ASME Code Section VIII. You need to do this test after completion of the construction process, but before the internal parts assembly and also before painting process. This content

  • We all have probably heard about destructive testing in welding. After all, those of us who are certified welders or work at a place that needs to certify welding procedures, have at one time or another heard about a bend test, or a charpy v-notch test. However, there are several types of non-destructive testing available. As you can imagine, performing destructive testing on

  • Weldingis an essential part of operating and maintaining assets in the petroleum (upstream, midstream, downstream) and chemical processing industries. While it has many useful applications, the welding process can inadvertently weaken equipment by imparting residual stresses into a material, leading to reduced material properties. In order to ensure the material strength of a part is retained

  • A crucial step in many welding applications, preheating slows the rate of cooling in a finished weld, lowers the amount of hydrogen in it, and reduces the risk of cracking. Artificially introducing heat into the base metal — by means of an external heat source — adds a step to the welding process; however, it can save you time and money in the long term by reducing the potential for a failed

  • PIPING HYDROSTATIC TESTING (OVERVIEW) Pressure source and test gauge should be upstream of check valve. If pressure source is downstream, check valve should have flapper removed or jacked?up. (Pressure must be released downstream of check valve after test completion.) Ensure that test blinds installed are the Correct thickness. Ensure that all items such as control valves, relief valves,

  • PostHeating In case of alloy steel materials such as Cr-Mo stels, if the post weld heat treatment is not performed immediately after welding, then the weld joint and adjacent portion of pipe, at least 50 mm on either side of pipe, shall be uniformly heated to 300°C. This temperature shall be maintained for half an hour minimum, and then wrapped with mineral wool before allowing it to cool

  • Welding Procedures are the guidelines used to perform a weld. They are designed to provide a record of the welding variables used and the inspection results obtained during the procedure qualification test. They can also provide the instructions for the welder to use in production in order to produce acceptable welds. Usually welding procedures are developed in accordance with a welding code or standard,

  • Preheating involves heating the base metal, either in its entirety or just the region surrounding the joint, to a specific desired temperature, called the preheat temperature, prior to welding. Heating may be continued during the welding process, but frequently the heat from welding is sufficient to maintain the desired temperature without a continuation of the external heat source. The interpass temperature,

  • Ensuring a topnotch weld inspection program​ Ensuring that welders follow specific procedures is a crucial step in the overall welding quality system. There are a number of reasons to inspect a weld, the most fundamental of which is to determine whether its quality is good enough for its intended application. To evaluate the quality of a weld, it is necessary to
