ASME Section IX Welding Certification
ASME Section IX (also called ASME 9) is a welding and brazing qualification. Northern Stainless is ASME Section IX certified, allowing us to utilize Shielded metal arc welding (SMAW), Gas tungsten arc welding (GTAW), or Gas metal arc welding (GMAW). Our welding and brazing acumen, including NACE Hardness surveys, has been approved by an American Welding Society (AWS) senior welding inspector, confirming our dedication to the highest standards of the metal casting industry.
NDT – Liquid Penetrant Inspection Foundry Control
Northern Stainless performs liquid penetrant inspection (LPI) in house as a foundry control. LPI is a cost-effective method of defect assessment in the surface of non-porous materials.
LPI detects surface imperfections such as porosity, as well as hairline and fatigue cracks on in-use components. Delivering an order with flaws to our customers is simply unacceptable.
