Chabot College Welding Courses

Chabot College offers students a unique educational opportunity. The College believes strongly that all individuals must be given an equal opportunity to reach their highest potential in preparing themselves to face a rapidly- changing world. Our institution is dedicated to serving the community by providing an excellent learning-teaching environment, which will enable you to achieve fulfilling and productive lives.

Among many resources and programs that our college offers, this web page enables you to take a good look at the technical and career-vocational educational welding program. Why the welding program? Because of the big demand of highly qualify and skilled welders, able to understand and perform their tasks using state the art welding equipment. Overall, welders are less affected by volatility of the economic cycle and the possibility of layoffs then other workers are. A skilled welder is part electrician, metallurgist, chemist, designer, and mechanical engineer. Welders are respected for what they do and what they know. The first step in that direction is simply to take your first welding course. I hope you will seize the opportunity and enjoy the knowledge and training that will enable you to pursue a career as a welder.
