Hot work needs the right coverage.
General liability, workers' comp, tools and equipment and commercial auto for shop and mobile welders, fabricators and structural steel contractors.
Quick answer A welder or welding business typically needs general liability for fire and property damage from hot work, workers' comp, tools and equipment coverage, and commercial auto for welding rigs and trucks.
- Welding is hot work, and fire damage on a job site is one of the most common and costly claims welders face.
- Welding businesses need workers' comp when they have employees, and all licensed contractors will need it from 2028.
- Commercial auto covers a welder's truck, while equipment coverage protects the welding machine and tools.
- Structural steel and height welding work carry higher insurance rates than other welding work.
- Because hot work can start fires, carriers price welding fire risk carefully, and fire watch and permits help.

Welding insurance, answered
Why is welding liability expensive?
Hot work can start fires, so carriers price fire risk carefully. Fire watch and permits help.
Is structural work rated differently?
Yes. Structural steel and height work carry higher rates.
Is my welding rig covered?
Commercial auto covers the truck. Equipment coverage protects the welder and tools.
Do I need workers' comp?
Yes, with employees, and for all licensed contractors from 2028.
Do you offer welding insurance outside California?
Yes. Clients across the country send the same quote form. California policies are placed directly; outside California the request is handled together with a partner agency in your state, and the shopping across carriers works the same way. Rules, minimums and markets differ by state — see insurance requirements by state.
