The Story Behind Wahl's On-site Welding

Founded in 2018, Wahl's On-site Welding And Repair LLC began with a vision: deliver the kind of skilled, mobile welding support heavy industries need — fast, safely, and reliably. Backed by over 18 years of field welding experience, Spencer Wahl built the company on grit, craftsmanship, and commitment to doing the job right the first time.



From a single mobile rig to a trusted name in the Northeast’s industrial repair scene, the company has grown without ever losing its focus on quality and accountability.
