At Legacy Welding LLC, our name says it all. We’re not just building parts — we’re building a legacy of strength, reliability, and hard-earned craftsmanship that lasts for generations.
Founded by Jonathan Leftwich, Legacy Welding is the result of decades of experience, grit, and a relentless pursuit of excellence. Jonathan’s welding career began early, sparked by a passion for creating with his hands and a deep respect for the trades. That passion quickly became a profession, and he soon found himself on the road with the Boilermakers Union, traveling across the country and contributing to the construction of massive, high-stakes projects — from petroleum tanks to power plants and everything in between.
Jonathan holds an impressive range of professional certifications that reflect his technical mastery and commitment to industry standards, including:
- AWS D1.1 – Structural Welding (Steel)
- AWS D14.1 – Welding of Industrial and Mill Cranes
- AWS D1.6 – Structural Welding (Stainless Steel)
- ANSI / AWS B2.1.002-09 – Performance Qualification
- ANSI / AWS B2.1-84 – Welding Procedure and Performance Qualification
- Kentucky DOT KM611-110 – State DOT Welding Certification
Over nearly two decades on the road, Jonathan not only sharpened his technical skills but also gained a deep understanding of what quality, safety, and professionalism really look like in the field. He worked with some of the toughest crews on some of the most complex builds — and through it all, one goal remained: to one day run a business that would carry his values forward.
That goal became a reality with the establishment of Legacy Welding LLC — a full-service mechanical and fabrication business committed to high-quality work across metal and non-metal applications alike. From new builds to repairs, from custom fabrication to on-site welding, Legacy Welding offers solutions that are tough, dependable, and built to last.
Jonathan built Legacy Welding to reflect everything he learned in the field:
- No shortcuts
- No excuses
- Just honest, hard work — done right the first time
Today, Legacy Welding continues to grow, serving clients across industries with the same integrity and pride that Jonathan started with. Whether you’re a contractor needing structural steel, a plant manager requiring precise repairs, or a property owner looking for custom metalwork, you can count on Legacy Welding to deliver.
Because when you hire Legacy, you’re not just hiring a welding crew — you’re becoming part of the legacy.
