Hiring a welder in Wisconsin
How do I find a mobile welder in Wisconsin?
Filter the providers below by "Mobile" or "Both" to see who travels. Mobile rigs in Wisconsin cover service radiuses from 30 to 200 miles depending on the operator — radius is listed on each profile.
What's the difference between a shop and a mobile rig?
A shop is a fixed location with fab tables, lifts, and (usually) a crane. Better for structural work, larger fabs, or jobs that need controlled conditions. A mobile rig is a truck-mounted welder-generator combo that comes to your site — better for emergency repairs, ranch and farm work, and anything bolted down.
Do providers in Wisconsin carry insurance?
Each provider sets their own. Look for the "Verified" badge — it means we've checked documentation. Always confirm current insurance directly with the provider before work begins.
What materials should I expect?
Most Wisconsin shops handle steel and aluminum at minimum. Stainless, cast iron, and pipe are specialty — filter by material if you need them.

Shops and mobile rigs join Wisconsin as the directory grows. Leave your email and we'll tell you when a new welder that fits your job lists — no middleman, no fee.
