Shielded Metal Arc Welding

Book excerpt: Shielded Metal Arc Welding provides thorough instruction in the shielded metal arc welding process through 35 concise and easy-to-understand lessons. Each new concept is presented in a separate unit, allowing students to focus on one area of instruction at a time. Students will find the concise, write-in text unintimidating and clearly illustrated as they progress from the study of basic welding concepts, such as welding safety and basic weld joints, to more challenging welding techniques, such as welding thin sheet metal, aluminum, and pipe. In addition to providing instruction for shielded metal arc welding in all welding positions on ferrous and nonferrous metals, this text also provides lessons on surfacing and padding, strategies for controlling distortion, weld inspection and quality control, and welding careers. This text helps prepare students for the Knowledge Tests and Welder Performance Qualification Tests for Module 4 of AWS SENSE Level I--Entry Welder certification. It also explains the interpretation of AWS welding symbols, teaching students to properly read welding drawings and blueprints.
