flame. • Keep the hot end of the welding rod in the weld pool or within the flame envelope. • When the weld is complete and still in the red heat, circle the outer envelope of the torch around the entire weldment ... torch away from the weldment to ensure a slow cooling rate. Chrome Molybdenum The welding technique for chrome molybdenum (chrome moly) is practically the same as that for carbon steels, except for sections over 3⁄16-inch thick. The surrounding…

almost anyone with some basic mechanical skill, dexterity, and practice can learn to weld. There are three general types of welding: gas, electric arc, and electric resistance. Each type of welding has several variations, some of which are used ... soldering of various metals. Types of Welding Gas Welding Gas welding is accomplished by heating the ends or edges of metal parts to a molten state with a high temperature flame. The oxy-acetylene flame, with a temperature of approximately…
