Welding standard root face.

In preparation for base metals, what is the standard bevel required?

These are generated in a welding job due to the faulty or poor technique used by the inexperienced or unskilled welder or due to fundamental difficulties in the welding operation.

A weld defect occurs when the depth of the welded joint is insufficient.

Is defined as the distance from the base plate top surface to the maximum extent of the weld nugget.

Is a group of small voids and blowholes that are comparatively bigger isolated holes or cavities.

These are small metal particles that are thrown out of the arc during welding and get deposited on the base metal around the weld bead along its length.

It is the change in the shape and difference between the position of two plates before and after welding due to the temperature gradient present at various points along the joints.

It is the change in the shape and difference between the position of two plates before and after welding due to the temperature gradient present at various points along the joints.

It is a kind of weld defect which forms a groove in the parent metal along with the sides of the weld bead.

It reduces the thickness of the plate and also reduces the strength of the weld.

It is due to the tearing of the grain boundaries of weld metal before complete solidification has taken place and the metal is still in the plastic state. 

A shallow fusion between weld metal and base metal.

It is due to excessive heat input and creates a hole.
