Nondestructive Testing service providers

  Non Destructive Testing has plenty of scope for people interested in Mechanical Industry and also construction sector. This Quality Control Related subjects is thought in almost all major cities all over the world, and the NDT certificates offered by institutes are valuable across the globe. The techniques thought during the courses are applicable to almost any manufacturing &  construction sector, which gives the Trained/ certified persons job opportunities in vast areas. Job opportunities are in foundries, steel Plants, aluminum smelters, Oil & Gas extraction plants, refineries, Plant Construction, railways manufacturing, automobiles machine shops, transport equipments fabrication, earth movers manufacturing, civil structures and pre-fabricated structures. The course fees for NDT varies from 20,000 INR to 3 Lakhs approx or even more depending on the standard which we choose for up gradation. The below are the standards (with abbreviations / Full form)  in whic...

  Welding Procedures Follow a clear example of  test coupons welding procedures for a  3G welding certification . In this 3G  welding procedure the notes were taken from the  same section of the AWS code  that are used for the  3/8 inch  limited thickness test procedure. The  test coupons  shall be  pre-cut  and ready to prepare. The welder shall grind the face of the test plates a minimum of one inch back from the bevel and a minimum of a quarter of an inch. Next the backing bar to bare metal shall be cleaned with a grinder and cleaned the oxidation off of the bevel, to bare metal. After the Welding Inspector will check the bevel angles with a protractor. 1. The Root Pass: The welder shall set to  root opening with two 1/8 inch  welding electrodes and then the test plate shall be inspected for fit-up. The test coupon shall be put in a  vertical position  and marked with a  white marker  to make su...

  Failure investigation often   uncovers facts  that lead to changes in design, manufacturing, or operating practice, which will eliminate similar failures in the future. Failures of insignificant parts can also lead to advances in knowledge and should be done objectively, as with a large structure. The following four areas of interest should be investigated to determine the cause of weld failure or weld defects and the interplay of factors involved: Initial observation . The detailed study by visual inspection should be made at the failure site as quickly as Photographs should be taken, preferably in color, of all parts, structures, failure surfaces, fracture texture appearance, final location of component debris, and all other factors.   Background data . All information concerning specifications, drawings, component design, fabrication methods, welding procedures, weld schedules, repairs in and during manufacturing and in service, maintenance, and service use.
