Q:What is the standard for the porosity of welded joints?

According to national and industry standards, the porosity of welded joints should generally not exceed 3%. If the porosity exceeds 3%, the mechanical properties and corrosion resistance of the welded joint will be affected, resulting in fatigue fracture and damage to the weld. Therefore, when conducting welding quality inspections, the porosity of welded joints needs to be strictly controlled to ensure that it meets the standard requirements.
