How Welders Structure Their Invoices
List materials separately from labor. Clients want to see what they are paying for steel vs. what they are paying for your time. Specify the welding process — MIG, TIG, and stick welding have different rates and applications.
Shop rates vary by certification level and work type. Structural welding typically runs $75-110/hr. Specialty work (TIG aluminum, stainless, aerospace) commands $110-150/hr. Always note any AWS or ASME certifications held — certified welding work justifies higher rates and clients need to know what they are getting.
