Welding defects can be classified as structural discontinuities and consist of: porosity, slag inclusions, lack of fusion, cracks, etc.
Porosity is gas pockets or voids in the weld metal which are free of any solid materials, such as It is formed as a result…
NDT Course fees depends on the type of NDT Course Selected, such a number of methods and the International standard chosen for the certification
The Average course fees for General NDT course will be Rs.17500,
This course fees Rs.17500 is for ASNT Level II Certification course…
Elements of Welding Symbols:
The first concepts the Welding Inspector must understand very well, are the welding symbols and how to interpret them on drawings. The reference line of the welding symbol, as shown below, is used to designate the type of weld to be…
Here are some rarely used NDT – Few Other Methods
1. Eddy Current Testing – ET:
Eddy-current inspection uses electromagnetic induction to detect flaws in conductive materials. A circular coil carrying current is placed in proximity to the test specimen (electrically conductive). The alternating current in…
Positions for Welding Pipe
For welding pipe in shops, power plants, oil refineries, and chemical plants for crude oil, gasoline, and natural gas, the same basic welding positions described previously are used.
Flat Butt Weld Pipe Position…
Standards for Piping Design and Inspection:
The original ASME B31 Code for
Pressure Piping was first introduced in 1935 as the single document for piping design.
In 1955, ASME began to separate the code into sections…
ACOUSTIC EMISSION TESTING (AET)
Acoustic Emission Test is a type of Non – Destructive Test method generally used for detecting and locating imperfections in mechanically loaded structures or components.
Flaw origination and progression in a stressed component can be identified by acoustic emission test method.This…
Non Destructive Testing , NDT , is industrial method for analyzing the characteristics of material or finding the discontinuities in the material & Weld joints, without damaging the material.
NDT is otherwise called as, Non Destructive Evaluation –NDE, Non Destructive Inspection (NDI) and it a…
This blog will let you know about the principle of Ultrasonic testing
What is Ultrasonic Testing?
Ultrasonic Testing Uses high frequency sound energy to conduct examinations & make measurements.
It can be used for flaw detection, Dimensional measurements.
