Stress remaining in a structure or member, as a result of thermal and/or mechanical treatment. Stress arises in fusion welding primarily because the melted material contracts on cooling from the solidus to room temperature.
Welding Tech
Weld metal, at the face or root, in excess of the metal necessary to fill the joint.
A gas flame that has a reducing effect, due to the presence of excess fuel.
A test in which a transverse section of the weld is located in the center of the reduced section of the specimen.
