About Ernie's Welding
Your MRI quench vent system is a critical safety component. When a magnet quenches, helium gas must be vented safely and efficiently. That’s why hospitals, imaging centers, contractors, and OEMs rely on Ernie’s Welding & Fabricating for precision-built MRI quench vent systems manufactured in the USA.
Since 1972, we’ve designed and fabricated stainless steel quench vent components that meet demanding industry requirements. From replacement parts to complete custom vent systems, every component is built with quality, accuracy, and fast turnaround in mind.
Whether you’re installing a new MRI, upgrading an existing system, or replacing damaged components, our engineering and fabrication team can provide the right solution.
