One cause is excessive flux burden (the amount of flux deposited). Excessive flux burden can cause weld bead distortion, as well as pockmarking and porosity. Inconsistent weld toes and rough weld ripples, known as chevrons, stem from the weight of the excessive flux. Flux burden should be deep enough to prevent welding arc flash-through but still allow the operator to

Many shops go to great lengths to limit welders’ exposure to welding fumes: weld fume extractors, respirators, ventilation improvements in welding booths. But what about limiting fume exposure for the shop’s nonwelders? Welding fumes are not something to be ignored. Prolonged exposure can lead to short-term health problems like sinusitis, colds, and irritation of the nasal, mouth, and lung cavities;

Despite his young age, 27-year-old Sun Jianjun is a seasoned welder with nine years of experience. In April 2015, as a high school student, Sun moved from his hometown of North China’s Hebei province to Wuhan, the capital city of Central China’s Hubei province. At the age of 18, he decided to pursue further studies at a welding training institution

It is impossible to start off any article on welder training without stating what everyone already knows. First and foremost, there’s a shortage of welders in the U.S. and there doesn’t seem to be a surefire fix for this any time soon. As the situation exists today, the older welders in the workforce are reaching retirement age at a faster

Finding time to get away from the shop can be difficult. But when the time away is connected with potential investments that might make the company more efficient and create more manufacturing capacity, that’s time well spent. With that in mind, it’s no wonder that so many metal fabricators attendFABTECHon an annual basis. More than 40,000 made the trek to

How much wood would a welder weld if the welder could weld wood? Todd Noe wasn’t really interested in finding out while a student at San Dieguito High School in Encinitas, Calif. He didn’t like waiting around to move on to the next step. “I didn’t have the patience for wood—to let the thing sit up with some wood glue

Editor’s Note:On Sept. 20, Jason Becker, host of theArc JunkiesPodcast, recorded an episode titled “WPS, PQR, WPQR, and other acronyms,” withLincoln ElectricCharlie Cross, welding technical specialist, and Padraic Bean, weld process consultant. The episode, part of theAWSWelding Wednesday series, focused on welding procedures and procedure qualification records and their importance in delivering quality fabrications. Developing a welding procedure specification (WPS)

When it comes to artificial intelligence (AI) and its subset, machine learning, many in the metal fabrication industry see them being applied only in a distant future. Those methodologies expanded to engineering, biotechnology, marketing, and other fields beyond manufacturing. They ushered in Six Sigma and other tools to improve business processes by reducing the number of defect opportunities, minimizing variation,
