XYZ-Welding

These flashcards cover key vocabulary related to welding and material science as discussed in the lecture.

X-ray

A form of electromagnetic radiation with a very short wavelength, used in radiographic testing (RT) to inspect the internal integrity of a weld.

Yield point

The first stress in a material, less than the maximum attainable stress, at which an increase in strain occurs without an increase in stress.

Yield strength

The stress at which a material exhibits a specified limiting deviation from the proportionality of stress to strain.

Young's modulus

A measure of the stiffness of an elastic material, defined as the ratio of the stress to the strain in the elastic region.

Zero-defect

A quality control concept that aims for the elimination of all defects in a manufacturing or welding process.

Zirconiated tungsten (EWZr)

A tungsten electrode that contains a small amount of zirconium oxide; it is used primarily for AC welding of aluminum and magnesium because it retains a balled end and is highly resistant to contamination.
