Summary

Summary

This hands-on guide to welding covers everything a beginner needs to know to work safely and productively with welding equipment. Starting with the basics of setting up a welding outfit and with a focus on oxyacetylene welding, this book discusses new processes, fuels, equipment, supplies and welding techniques in an easy-to-understand format. It even covers safety issues and how to set up your own welding workshop. it also provides welding projects for beginners to try out what they've learned. Its an ideal hands-on learning tool for beginners and an excellent bench reference for experienced welders.
