California does not have a statewide general business license, but most cities and counties require a local business license or business tax certificate. Businesses must register with the California Secretary of State for entity formation, obtain a seller's permit from the California Department of Tax and Fee Administration if selling taxable goods, and register with the EDD for payroll taxes if employing workers. San Francisco, Los Angeles, and other major cities have their own business registration and tax requirements.

Frequently Asked Questions

Starting a welding business typically requires $15,000–$40,000, covering welding equipment ($3,000–$8,000), a vehicle and trailer ($3,000–$10,000), safety equipment ($500–$1,000), insurance, and working capital. A mobile welding setup serving job sites has lower overhead than a fixed shop.

Shop welding rates range from $65–$125/hour. Mobile and structural welding commands $85–$175/hour. Certified pipe welders earn $35–$50/hour as employees or $100–$200/hour as contractors. Custom fabrication is often quoted as a fixed project price with 40–60% material markup.

Certifications aren't legally required for general repair and fabrication work, but AWS D1.1 structural steel certification is required for many commercial, government, and infrastructure projects. Pipe welding certifications (6G position) can triple your earning potential in oil/gas and industrial sectors.

Mobile welding has lower overhead (no shop rent) but higher vehicle and fuel costs. Shops enable more complex fabrication but require $2,000–$8,000/month in rent. Many welders start mobile and transition to a shop as volume grows. Specializing in one niche (agricultural repair, pipeline, custom automotive) typically yields the highest returns.
