Orange Coast College welding students have captured first place in the American Welding Society (AWS) poster competition for the third year in a row.

Jason Rhoton of Huntington Beach, Lam T. Lam of Garden Grove and Steven Zeal of Fountain Valley submitted the winning poster describing their project, "The Effect of Arc Gap When Using Active Flux." Faculty advisor for the winning entry was David Belzaire. Zeal also participated in last year's winning entry.

Active fluxes have been developed to improve the depth and consistency of weld penetration in austenitic stainless steels, according to Zeal. The effectiveness of these fluxes is dependent on the arc length used, he explained. In the OCC experiment, students evaluated the effect of arc length on weld penetration of orbital welds in stainless steel. The project showed that use of the flux increased the weld penetration. The students also determined that the effectiveness of the flux increased as arc length increased.

The FABTECH conference, held in Las Vegas this year, is North America's largest metal forming, fabricating, finishing and welding event with more than 35,000 visitors and 1,300 exhibitors. The conference includes workshops presenting the latest technology, cutting-edge topics and industry experts.

FABTECH is co-sponsored by five industry-leading associations: the American Welding Society (AWS), the Fabricators & Manufacturers Association, International (FMA), the Society of Manufacturing Engineers (SME), the Precision Metalforming Association (PMA), and the Chemical Coaters Association International (CCAI).

Winning the competition is "a testament to the ability of our students and strength of our program," Bezaire said. He noted that there are many career options for welding students, including inspectors, welding engineers and lab technicians.
