Can Your Foundry Weld This? SF&E Can.

Stainless Foundry & Engineering, Inc. (SF&E) casts over 250 alloys. When pouring that many materials, from time to time, we are required to perform repair welds to remove surface casting defects. Initially, we always attempt to blend and grind surfaces to meet customer contract requirements. However, we cannot remove all indications by blend and grind, so we utilize our ability to perform weld repair.

SF&E has a vast library of weld upgrade procedures for almost all weldable grades of material that we produce. We take pride in this initiative because it helps us control the quality of the finished product, and it is an important part of what makes us a one-stop shop for customers. In addition, our advanced welding services are an offering not many foundries provide.

Stringent Weld Requirements

SF&E imposes 100% compliance to the requirements of our customer purchase orders and material specifications.

SF&E follows the most stringent weld requirements such as:

ASTM (American Society for Testing and Materials) A488 – Steel Casting Welding, Qualifications of Procedures and Personnel
ASME (American Society of Mechanical Engineers) Boiler and Pressure Vessel Code, Section IX – Welding, Brazing & Fusing Standards
NAVSEA (Naval Sea Systems Command) S9074-AQ-GIB-010/248 Requirements for Welding and Brazing Procedure and Performance Qualification
NACE (National Association of Corrosion Engineering) MR0175/ISO 15156, Parts 1-3
Numerous other welding-related requirements from customer specifications

Personnel Certifications

To meet all the codes and standards listed above, we are required to certify our welding personnel to various practices. The qualifications our welders obtain allow us to perform weld repair, upgrade, and/or overlay for most of the weldable alloys poured. We have training and support programs, as well as third party certification activities from European Registrars (TUV-SUD), that support our practices. Additionally, we have a NAVSEA compliant Welder Workmanship Program, required for welding Navy and DOD (U.S. Department of Defense) work.

Our welding personnel are experts at the processing of castings needing repair.

Nuclear and NAVSEA – SF&E’s Quality Assurance Department performs annual vision screenings with our welders to ensure they meet the requirements of the ASME BPVC, Part 1, Section III for nuclear work and NAVSEA Tech Pub.
Nondestructive Evaluation – We ensure our welders are certified in accordance with the American Society of Non-Destructive Testing SNT-TC-1A Liquid Penetrant (PT) and Visual Testing (VT) by our on-site NDE (Nondestructive Evaluation) Level III. This allows them to verify their own work prior to our Quality Assurance Department Level II personnel certifying the preparation to weld or final welded locations.
Pressure Equipment Directive – To meet the stringent requirement for welding castings in accordance to the Pressure Equipment Directive (2014/EU/68 PED), our welders are qualified in accordance with EN287.
Broad Range of Material Grades – SF&E is qualified to weld many European grades of material as well as over 100 material grades for PED Particular Material Assessment (PMA) orders.

When you place an order at SF&E, we have the programs and personnel to ensure that welding can be performed and will be done so to meet all needs and requirements. To learn more about our welding capabilities, contact SF&E at sales@stainlessfoundry.com.

Non-Galling ILLIUM 8 Alloy Is the Right Recipe for Food Processing Equipment

Nickel-based ILLIUM 8 alloy has qualities that are ideal for food, dairy, and pharmaceutical processing equipment, as well as petrochemical equipment. We have been pouring ILLIUM alloys for decades, continuously working to improve our processes with every pour. Learn more about ILLIUM 8, and how its non-galling and corrosion-resistant qualities make it a critical component to the success of some of our most vital industries.

Clyde Union® Pumps Keep The Oil Flowing On Offshore Drilling Platform

One of the most rugged workplaces in the world is located nearly 200 miles off the Newfoundland coast on the Hibernia oil production platform. To ensure the oil keeps flowing, Stainless Foundry and Engineering recently worked with the pump manufacturer Clyde Union Canada Ltd., to upgrade the platform’s three centrifugal pumps.

Supporting the Global Defense Supply Chain

All major weapons systems contain a metal casting. Stainless Foundry & Engineering works with different alloys and techniques to produce castings that are better equipped to support the defense industry needs, anywhere from submarines to advanced weapons systems.

High Spec Castings – What You Need to Know about Testing

Parts produced for the nuclear, petrochemical, power generation, military, and defense industries require a high level of specification. Thorough testing is imperative to ensure these critical castings not only meet customer and industry standards, but they have the structural integrity to perform throughout their expected service life. Here’s how we do it.

Anatomy of a Pour: Investment Casting Photo Story

When Stainless Foundry & Engineering (SF&E) opened its doors in 1946, we specialized in sand casting, primarily producing impellers for pumps. SF&E added investment casting to its service offering in 1968 in response to the increasing demand for precision parts. We’ve documented our investment casting process in a series of photos as a way to pay homage to this practice, which dates back to 3,000 B.C.
