Stick welding calls for expertise in electrodes. Stick electrodes consist of a flux, an encased cable which determines how an electrode is utilized. The American Welding Society (AWS) classifies the 6012 welding rod as a popular stick electrode.
Use 6012 welding rods to connect an open link between two joints. Professional welders use 6012 electrodes in the horizontal position for its speedy, high-current fillet welds.
In an E6012 electrode, E stands for electrode. The initial two numbers signify the minimum tensile strength, which is determined in pounds per square inch (psi). The number, 60, in an E6012 electrode creates a weld bead with a minimum tensile strength of 60,000 psi. The third number ,1, indicates the electrode can be used in every position. The fourth number denotes the coating type and welding current.
Two drawbacks for the 6012 rod include its thin penetration profile and extra post-welding clean-up because of its thick waste material from smelting.
Match the stick electrode to the base metal strength. E60 electrodes work best with mild steel. Choose the welding point and power source. After determining the joint design and fit, pick an electrode that will most likely pierce the metal.
