The Challenge: Catastrophic Failures & Unknown Root Cause
Northern Manufacturing specializes in providing advanced fabrication solutions for OEMs, particularly excelling in high-stakes projects involving critical components. We combine precision engineering with cutting-edge technology, such as automated laser preparation and robotic welding, to guarantee weld integrity and overall product reliability. Our approach focuses on de-risking supply chains, eliminating field failures, and significantly reducing the total cost of ownership for our clients.
- Catastrophic Weld Failures: A key component (high-temperature heat exchanger) in their flagship machine was experiencing widespread weld failures in the field.
- Significant Downtime & Warranty Costs: Failures led to machines being taken out of service, resulting in exceptional unplanned downtime for customers and substantial warranty expenses for the OEM.
- Damaged Reputation: The recurring failures were harming the client’s reputation for reliability.
- Unknown Root Cause (Suspected): The client suspected improper welding (inadequate joint preparation, incomplete weld penetration) from their previous supplier but needed a definitive solution.
- Need for a New Supplier: They required a new stainless steel fabricator capable of not only producing the part but also engineering a permanent solution to mitigate technical and financial risks.
The Northern Manufacturing Solution: Advanced Manufacturing & Technical Deep Dive
Northern Manufacturing approached the problem with a process-driven methodology, identifying the root cause in the interaction between joint geometry and the welding process. Our solution involved a two-part technological upgrade:
Precision Joint Preparation: Utilized our Trumpf Tube Laser 7000 to machine a perfect, consistent 35° bevel on every tube edge, creating the ideal geometry for a full-penetration weld, eliminating inconsistent manual grinding.
Automated Welding Consistency: Deployed advanced robotic welding cells to execute welds. The combination of robotic precision and a qualified Welding Procedure Specification (WPS) ensured every weld was identical, repeatable, achieved full penetration, and eliminated human error.
Technical Deep Dive: Process Control & Advanced Technology
Northern Manufacturing approached the problem with a process-driven methodology, identifying the root cause in the interaction between joint geometry and the welding process. Our solution involved a two-part technological upgrade:
- Project Focus: High-temperature stainless steel heat exchanger assembly.
- Materials: Specific series of high-temperature austenitic stainless steels, selected for superior performance in high-heat, corrosive food processing environments.
- Cutting & Preparation: Trumpf Tube Laser 7000 processed tubing with a precise 35° bevel.
- Welding Process: Robotic Gas Metal Arc Welding (GMAW) for joining tube and elbow sections, governed by a WPS qualified to AWS D1.6 (Structural Welding Code for Stainless Steel).
- Quality Assurance: Managed under ISO 9001:2015 certified Quality Management System, with on-staff Certified Welding Inspector (CWI) overseeing first article validation and production inspection.
The Outcome:
By blending engineering discipline with cutting-edge fabrication technology, Northern Manufacturing delivered transformative results that went far beyond the client’s expectations.
- Elimination of Field Failures: Achieved a 100% success rate for new assemblies in the field, completely eliminating costly downtime and warranty claims.
- Supply Chain De-Risking: Transformed a high-risk, unreliable component into a stable and predictable part of the client’s supply chain.
- Reduced Total Cost of Ownership: Delivered a superior, failure-proof product for $69,000, which was a 23% cost reduction from the client’s target price of $90,000, along with the elimination of warranty costs.
Client Testimonial:
“We trusted Northern with our target price and our biggest technical problem. They not only solved the issue permanently, but they came back with a final price 23% under our target. That level of integrity showed us they weren’t just a supplier; they were a true partner. It solidified our long-term relationship.”
