About L J's Welding & Fabrication
L J's Welding & Fabrication is a family-owned welding and fabrication business based in Waterloo, Iowa. The company was started by Leo James Kruth (known as LJ) and his wife Marlene after LJ retired from a 30-year career as a maintenance welder at John Deere, turning decades of industrial experience into a shop focused on custom welding, repair, and mobile field services. The shop provides a full range of metalworking capabilities: welding of mild steel, aluminum, and stainless steel; custom fabrication using CNC plasma cutting, CNC routing and machining, CNC press brake bending, and CNC saw cutting; CAD design and drawing; metal cutting, shearing, and raw material processing; and steel sales with custom components. Repair services cover heavy equipment, trailers, structural components, and automotive frames. The company serves agriculture, automotive, residential and commercial construction, manufacturing and industrial facilities, and the trailer and heavy-equipment sectors. It also supplies specialized manufacturing support such as custom tools, flow racks, material-handling solutions, and safety-focused access ladders built to exact specifications for production lines. L J's Welding emphasizes a repair-first mindset, D1.1-certified welders, and a safety-first culture rooted in the founders' John Deere background. The family-owned structure and mobile response capability are positioned as key differentiators for customers needing fast turnaround and dependable workmanship.
