High-integrity fabrication backed by certified processes, in-house metallurgical analysis, and strict compliance with AWS, ASME, and ISO standards. From prototype joints to production-scale structural welds, we deliver consistent, inspectable results.
MetalCore's welding and metallurgy division combines certified welding operators, automated robotic cells, and a dedicated materials lab to deliver structural and pressure-critical components that meet the most demanding industry codes.
Our team develops and qualifies Welding Procedure Specifications (WPS/PQR) tailored to your base materials, joint configurations, and service environments. Every weld is traceable, documented, and verifiable through rigorous NDT protocols.
Comprehensive joining and material analysis capabilities for complex engineering applications.
High-purity joins for stainless, aluminum, titanium, and nickel alloys. Ideal for orbital, root passes, and aerospace/medical tubing.
High-deposition processes for structural steel, plate, and pipe. Optimized for productivity with consistent bead profile and penetration.
Multi-axis robotic cells programmed for repeatable seam tracking, reduced heat input variation, and high-volume production.
Optical microscopy, Vickers/Brinell hardness testing, chemical analysis, and weld metal microstructure verification.
RT, UT, MT, PT, and automated phased array testing. Third-party witness points supported for client and regulatory audits.
Controlled PWHT in induction and batch furnaces. Pre-heat and interpass temperature monitoring to prevent HAZ cracking.
We engineer WPS/PQR packages for a wide range of commercial and specialty alloys.

Our welding operations are governed by a documented Quality Management System aligned with ISO 9001:2015 and AS9100 (for aerospace programs). All procedures are developed per AWS and ASME standards, with PQR testing conducted in our accredited lab or approved third-party facilities.
Every production weld includes full traceability: welder/operator certifications, consumable batch records, pre-heat logs, interpass monitoring, and post-weld inspection reports. We welcome client quality representatives and third-party inspectors for witness points and final NDE validation.
