Welding Symbols like leg weld and throat weld difference.

Question

Accepted Answer

Leg weld and throat weld are two types of welding symbols used to indicate the size and shape of a weld.

Leg weld refers to the length of the weld on one side of the joint, while throat weld refers to the minimum distance between the root and the face of the weld.
Leg weld is represented by a straight line perpendicular to the reference line, while throat weld is represented by a diagonal line.
For example, a leg weld symbol with a length of 1/4 inch would be represented by a straight line perpendicular to the reference line with the number 1/4 next to it.
On the other hand, a throat weld symbol with a minimum distance of 1/4 inch would be represented by a diagonal line with the number 1/4 next to it.
Understanding welding symbols is important for ensuring that the correct type and size of weld is used in a given application.
