Ultrasonic Testing involves utilization of ultrasonic sound waves to detect defects inside a material. The welded joints have possibilities of defects inside the welds , or sometime near the weld zone. The few of defects that are often found in welds are Porosity, Cracks, Slag Inclusion, Lack of fusion, Lack of Penetration, Root concavity, Crater pipes, sharp undercuts, Burn through, HAZ cracks and much more. These defects when located deep and cannot be viewed manually, Ultrasonic scanning  is utilized to detect these discontinuities. The conventional ultrasonic testing of weld joints method which is shown here is totally operator reliable.Therefore the international bodies requires the operator to be qualified as per a standard and the machine used also meets standards requirement. Where to learn NDT? The certification may be ASNT Level 1, Level II or Level III or PCN or ISO 9712 qualification. There are many best NDT training institute for NDT c...

Oil and gas pipelines are designed with wall thickness considering the facts of Design pressure + Corrosion allowance +safety factor. Corrosion thickness testing Using UTT: The corrosion allowance is decided by pre-existing data of corrosion rate for a specific environment and carrying liquid. Based on the corrosion rate the life of the pipeline or tanks is estimated. There are also possibilities that the corrosion rate may vary than predicted. Depending on the climate and processing fluids characteristics. So the wall thickness should be periodically checked to monitor the reduction in wall thickness. If any low thickness areas, lower than the minimum allowed wall thickness is noticed, the pipeline or tank shall be repaired. And also if the rate of corrosion is noted to be at a faster than estimated the pipeline or tanks life shall be redefined and next inspection period shall be planned earlier than planned initially. Corrosion rates can be calculated by finding the difference betwee...

All you need to know about Ultrasonic Testing from AQC- Best Ndt Training Institute and Ultrasonic Testing Service provider in Coimbatore , TamilNadu, India Ultrasonic Sound is sound propagating in higher frequencies that are not audible to human ear. Generally sound with frequency (Frequency number of cycles per unit time) more than 20,000 Hertz is known as ultrasonic. For creation of sound we need to vibrate any matter, therefore in Ultrasonic testing we make a crystal to vibrate in higher frequency (generally  20,00,000 times) to produce Ultrasonic sound waves. These sound waves travels into material , and gets reflected back when it hits any different matter of different elastic property. For the purpose of creation of sound and receiving of sound we use Piezoelectric Crystal. What is Piezoelectric Crystal? The crystal grains which makes mechanical vibrations when electricity is applied and vice versa. The Crystal creates electric energy when mechanically vibr...

Welder Certificate is a document that shows ability of a welder to make a quality weld in a particular welding process. The Certificate also denotes on which type of welding material and which position the welder is able to perform. A full penetration weld can be performed by welder who is qualified for full penetration & fillet. A welder qualified by vertical position (3G) can perform Flat and vertical in production and so on. These qualification ranges are mentioned in the certificates after referring the applicable codes and standards. Welders are qualified for different process individually. Welding process: Shielded Metal Arc Welding (SMAW)- Arc Welding Tungsten Inert Gas Welding (TIG/GTAW)- Arc Welding Metal Inert Gas Welding (MIG)- Arc Metal Active Gas welding (MAG)- Arc Flux Cores Arc Welding (FCAW)- Arc Electric Resistance welding (ERW) and Lot more.. Welding Qualification standards are given in AWS D 1.1 – Structural Welding ...
