Frequently Asked Questions
What is the average welder salary in California?
The average welder salary in California is $26-$40/hr for certified structural and manufacturing welders. Aerospace welders at defense contractors earn $30-$52/hr. Union ironworker welders earn $40-$56/hr in the Bay Area and LA. California has among the highest welder wages in the country but also the highest cost of living.
What is the most valuable welding certification in California?
AWS D17.1 aerospace is the highest-earning certification for Southern California given the concentration of SpaceX, Boeing, Northrop Grumman, and defense contractors. Union ironworker membership (which includes structural welding) is the highest-earning path in Bay Area and LA construction. API 1104 and ASME IX open industrial and pipeline work.
Is there a welding shortage in California?
Yes. California aerospace, defense, shipbuilding, and construction sectors face certified welder shortages. SpaceX in Hawthorne and Northrop Grumman in El Segundo are both active recruiters of certified aerospace welders. Union contractors in the Bay Area and LA report difficulty finding qualified structural welders.
How do California welder wages compare to cost of living?
California has the highest cost of living of any state. Bay Area union ironworker wages of $40-$56/hr are strong but housing costs in the Bay Area are extreme. Many California welders live in more affordable inland areas and commute to Bay Area or LA projects. Welders in the Central Valley have lower wages but significantly lower housing costs.
What is aerospace welding at SpaceX?
SpaceX in Hawthorne, California employs certified aerospace welders on spacecraft and rocket components. Welders working on Falcon 9, Falcon Heavy, and Starship components need AWS D17.1 certification and often additional SpaceX-specific qualification. SpaceX welders earn competitive wages with equity compensation in addition to base salary, making total compensation above typical defense contractor rates.
