The authors of Welding, 2/e have experience both in industry and in the classroom. Their industry experience brings together knowledge of welding and manufacturing, welding inspection and quality control, power source design, troubleshooting, and customer service. These experiences, combined with more than 50 years of instructional expertise, inspired the development of this textbook and its accompanying technology. David HoffmanMember, American Welding SocietyCertified Welding InspectorCertified CRAW TechnicianFox Valley Technical College An accomplished welder with thousands of hours of hands-on experience, Dave Hoffman has been teaching welding and fabrication for more than 25 years. He assisted with the development of an Associate Degree program in Automated Manufacturing at Fox Valley Technical College and developed an Associate Degree program for Welding Technology. He also received a state grant to redevelop the Metal Fabrication/Welding Diploma program for which he wrote program requirements, competencies, and the complete curriculum. After completing development of the Associate Degrees in Welding Technology, Dave tested and passed the requirements to become an AWS CWI and CWE. Shortly after, he got involved with AWS and was on the B5E Committee, helping to write the B5.5: 2000, Specification for the Qualification of Welding Educators. Most of the welder certifications in that standard were already certified, however some were not. Dave welded GMAW-S vertical up and overhead plates to certify the welding procedure used in the standard. A past winner of the prestigious Lincoln Award, Dave holds a B.S. in Industrial Education and an M.S. in Technical Education from the University of Wisconsin - Stout. He also holds (and wrote) a patent on a product he designed and built in his home shop, and since retiring from teaching, occasionally works as a weld consultant for training and testing in industry.
