Welding Classes

Learn Welding from an Industry Leader

Dave Barzetti performed his first weld, under the guidance and instruction of his father, "The Ole Buck" Nick Barzetti Sr. in 1970 at age 11. It was more than a bonding experience for the two. Dave purchased the shop from his father in 1984, and never looked back. He passionately teaches eager students from all walks of life, and enjoys watching people improve dramatically in just one hour! He sees welding as a valuable skill for any homeowner, as well as young people who may choose to pursue welding as a career
