Understanding these codes ensures that fabricators aren't over-engineering parts and that clients receive products that fit their structural requirements without unnecessary expense.

is the international standard titled "Welding — General tolerances for welded constructions." en iso 13920-bf

This class specifically governs the geometric tolerances of the weldment, including how straight a part is or how flat a surface must be. 2. Tolerance Tables for Class B (Linear & Angular) Tolerance Tables for Class B (Linear & Angular)

This notation tells the welder: "Use Class B for most features, but tighten up this specific surface." is widely considered the "standard workshop accuracy" class

Q: How do I determine the tolerance class for my welded construction? A: The tolerance class depends on the specific application, industry, and required level of precision. Refer to the standard or consult with a qualified engineer or inspector.

is widely considered the "standard workshop accuracy" class. It is the "Goldilocks" zone for general mechanical engineering—tight enough to ensure parts align during assembly but loose enough to be achieved by a skilled welder without specialized jigs or constant measurement. Practical Application
