Every welding project, from fabrication to repair, is completed one weld bead at a time. Whether you're just starting out or trying to improve your skills, the first step is to learn how to consistently run good weld beads.
Arc Welding I covers welding machines, AC/DC, polarity, welding leads, electrode holders and filter lenses along with demonstrations of the characteristics and uses of the common welding rods.
In-depth explanations of the basic fundamentals, with close-up video of the actual weld, include starting the arc, arc force, arc gap, rod angles, rod movement, travel speed, and setting the amperage.
Using digital editing to slow down and stop the motion, close-up demonstrations provide an understanding of the molten weld puddle, and show exactly where to watch the puddle during the weld.
Also included are extremely clear video demonstrations of actual welds in the flat, horizontal, vertical, and overhead positions using E6010/E6011, E6013 and E7018.
Along with providing more insight into watching and understanding the molten weld puddle, ARC WELDING II takes an in-depth look at metal preparation, fit-up, and welding techniques for different types of weld joints.
After a brief review of the basic fundamentals, Arc Welding II takes a closer look at watching the molten weld puddle to adjust the amperage, and maintain the proper travel speed, rod angle and arc gap.
Arc Welding II provides in-depth demonstrations of metal preparation, joint fit up, and welding techniques for Corner, Lap, T, and Butt joints, including V beveled with a back up bar and V beveled open butt.
Detailed explanations, along with close-up video of the actual welds, show how the amperage setting, travel speed, rod angle, arc gap and rod movement are used to control penetration, the shape and the quantity of weld.
