Introduction: What Is Shielded Metal Arc Welding (SMAW)? (01:49)
An arc is created when electrons cross from negative to positive, creating intense heat. In stick welding, a flux coating protects the weld puddle, adds alloying elements, and allows the puddle to cool. A safety tip is included.
Components of a Shielded Metal Arc Welding System (02:31)
Components include power sources, which are rated by their duty cycles. Concepts covered include AC, DC, DCRP modes, and equipment such as electrode holder and ground clamp. A safety tip is included.
Choosing the Correct Welding Rod (02:46)
Viewers learn SMAW electrode selection factors. Welding rods come in various diameters. Several all-purpose electrodes are featured. Always refer to the MSDS that comes with all welding rods.
Safe Welding Environment and Protective Equipment (03:31)
Viewers learn how to create a safe welding environment. Protective equipment includes personal protective equipment (PPE), and clothing designed to protect the welder completely. Safety tip warns about "arc flash" or "arc eye."
Setting Up a Shielded Metal Arc Welding System for Use (01:47)
Follow the steps to setting up and turning on an arc welder. Each step of the welding process preparation including cautions and safety tips are demonstrated and explained. Safety tip: Never drape an electrode cable over your shoulder.
Laying a Bead (05:11)
A quality weld means good penetration of welding joint, proper tie-in to other beads, and minimal defects that will pass code. Follow step-by-step instructions and demonstrations from striking the arc, laying the bead, and to restarting the weld.
Reading the Bead (01:42)
From time to time, inspect the weld slag bead for quality. Reading the bead will provide insights into welding variables that might need to be changed. Learn the qualities of a good weld. Computer graphics accompany this discussion.
Advanced Welding Techniques (03:21)
Advanced welding techniques include welding the five basic joint types. Follow step-by-step instructions and demonstrations for welding. Solutions for arc blow are included.
