More than 80 percent of the cost for a manual weld lies in the labor required to perform it. By choosing the right welding transfer mode and wire for gas metal arc welding (GMAW), you can reduce your overall cost and improve productivity and efficiency.

El CO2 y el argón son los dos gases más comunes para soldar, pero éstos en realidad funcionan bien juntos, ayudando al soldador a lograr un perfil de cordón, un control de salpicadura y una penetración óptimos.

Argon and CO2 are the most commonly used gases in gas metal arc welding (GMAW). Alone, each has pronounced advantages. Together they combine to neutralize each other’s weaknesses and capitalize on each other’s strengths, all while providing you with your desired weld requirements.

According to the American Welding Society (AWS), there will be a shortage of approximately 290,000 welders in the U.S. by 2020. Education doesn’t fall on the shoulders of just high schools, community colleges, and technical programs, it also rests with industry professionals who have the space, equipment, and the expertise on staff to demonstrate the best practices. Arming educators with this information will only help make the next generation of welders that much stronger. For those of you who are in areas where getting hands-on training for industry leaders isn’t possible, here are a few questions educators tend to ask.
