Final answer:
In welding, the joint formed when one plate edge is welded perpendicular to the surface of another is known as a T-joint, resembling a 'T' shape.
Step-by-step explanation:
The joint that is formed when one plate edge is welded perpendicular to the surface of another plate is commonly referred to as a T-joint in welding terminology. This type of joint is characterized by the two plates forming a 'T' shape when viewed from the side. In terms of actual bodily joints, the question information related to anatomical joints doesn't directly correspond to the concept of welding. However, if we draw an analogy, a T-joint in welding could be somewhat comparable to a plane joint in the body, as it involves two surfaces coming together at a perpendicular angle.
