2013 Arc Exposure Event at Butte College Sparks Interest in High School Welders


Entering its sixth year, the Butte College Welding Program successfully attracts high school students from all over Northern California.

Taking place January 15-18 at the college’s welding department, 134 high school students and 29 instructors will receive hands-on training in the latest welding technology techniques and equipment. 

Representatives from Miller Electric, Hobart Brothers, Smith Equipment, and MJB Welding Supply will offer presentations.  Also during the event, participants will be visiting Metal Works in Oroville for a tour and PG&E representatives will demonstrate a hot tie in at the Butte College Welding Technology Department.  

Twenty Butte College Welding Technology Program students will assist high school students in learning valuable welding skills that they can use to further their welding skills or enter a college career pathway after high school.  School participants are traveling as far north as Hayfork/Trinity and as far south as Clovis/Madera.

Strong supporters of this event include industry partners – MJB Welding Supply, Metal Works, Tinks Inc., Transfer Flow Inc., Sierra Nevada, and PG&E.
