Mechanics of Crack Tip Opening Displacement

Crack tip opening displacement is kind of a destructive testing that is applied to measure the fracture toughness of the material. In shortened form the method is known as CTOD. In this technique, a notch is made on the test...

What causes Weld Tungsten Inclusion

Tungsten Inclusion is the most occurring weld imperfection, mainly caused by the absorption of tungsten fragments in weld puddle. This problem is associated with tungsten inert gas welding process where an erroneous weld attempt with defected electrode may result in...

Solid Inclusions that impair Weld characteristics

The entrapment of unwanted solid particles impairs weld metal strength. Such weld imperfections are developed by the inclusion of solid substances like slag, flux, foreign metal or oxide. These inclusions are appeared singly or in clustered form. On the basis...

10 causes of Weld Porosity and their practicable prevention

Weld Porosity is referred to as cavities produced due to the entrapment of gas in weld metal. The introduction of gas in a weld is supported by some mistakes that ought to be eliminated. Porosity is categorized according to the...

10 ways how to control Hydrogen Induced Cracking

Hydrogen-induced cracking (also referred to as cold cracking), is caused by the diffusion of hydrogen in the crystal lattice of HAZ near the fusion boundary.  Atomic hydrogen is dispersed throughout the weld material, making it weak in mechanical properties. The...
