Question

A straight line drawn through the center of a weld and along its length is called the ________.

1) Axis
2) Centerline
3) Baseline
4) Midline

Answer 1

In the context of welding, a straight line drawn through the center of a weld and along its length is referred to as the centerline, which bisects the weld into two symmetrical halves.

Step-by-step explanation:

A straight line drawn through the center of a weld and along its length is called the centerline. This term is used to refer to a line that represents the middle of the weld, both in terms of length and depth, when observed in a cross-sectional view. The centerline theoretically divides the weld into two symmetrical halves, in a similar conceptual way that the baseline is perpendicular to the line from its middle to the object in geometrical definitions. Moreover, within the context of optics, when discussing a lens, a ray that passes through the center of the lens is not deviated, as the center of the lens can be thought of as the origin, or the meeting point of axis in a Cartesian coordinate system.
