EWI researchers worked with shipyards to identify the soundness and productivity of aluminum joints welded with four different types of GMAW.
Experiments show that FE-based alloys welded with the FCAW process have higher wear resistance when no gas shielding is used.
AWS competitions often involve flying sparks and the crackling sound of welding. The AWS Poster Competition is different. It’s designed to test a welder’s ability to investigate, think creatively, and communicate effectively; skills that employers say are often lacking in their job candidates. According to Thomas Lienert, AWS vice president and chair of the Technical … Continue reading AWS Poster Competition Tests Skills Employers Need
Children’s books about welding aren’t exactly a dime a dozen. So I was delighted to have recently come across the Metal Man by Aaron Reynolds. This beautifully illustrated book is nothing less than a lyrical ode to the creative spirit inherent in welding. It tells the story of a seemingly ordinary summer day in the … Continue reading The Metal Man: An Inspiring Children’s Book About Welding and the Power of Art
Researchers examine operational, metallurgical, and in-service issues related to duplex stainless steels, including discussions on multipass welding and brazeability.
Resistance spot welding (RSW) has been a mainstay in the automotive industry for many years. In fact, the typical car body contains 4500 spot weld joints. As a result, the American Welding Society’s (AWS) D8 Committee on Automotive Welding has long published periodically updated editions of D8.1 Specification for Automotive Weld Quality – Resistance Spot … Continue reading New AWS D.8.2 Code Responds to the Rise of Aluminum in Auto Manufacturing
Researchers show how multi-pass friction stir welding (FSW) can be used to overcome the limitations imposed by the length of the tool pin in order to join thicker materials.
By most accounts, having to expand your welder training facility by several thousand feet just to keep up with the influx of new students is a good problem to have—if you have the money. The Pennsylvania College of Technology finds itself in just such a quandary. According to Dr. Davie Jane Gilmour, welding continues to … Continue reading Welding Programs Seek Funds to Meet Rising Demand
A new edition of the D3.6M, Underwater Welding Code was recently published and includes numerous updates. The internationally recognized code for the welding of structures underwater in both wet and dry environments was first published in 1983 and is currently in its 6th edition. The 2017 edition includes the following changes: The clauses have been … Continue reading AWS Releases New Edition of D3.6M, Underwater Welding Code
Chris Guise has made a career out of patrolling roads and waterways. He patrolled the roads for more than seven years as a Terrebonne Parish Sheriff’s Office deputy. Since he joined the Sheriff’s Office Water Patrol in 2004, he’s kept watch over the parish’s teeming waterways and wetlands. The amphibious deputy is on call 24 … Continue reading Meet the Welding Patrolman
