One drawback to the SMAW process is that it is slow. The equipment and materials are inexpensive, portable and relatively simple to operate even in outdoor conditions. SMAW (Shielded Metal Arc Welding): Commonly referred to as stick welding, SMAW is the most commonly used welding process today. Prospective tank buyers should be aware of the different processes. Each of the four processes will repeatedly produce quality weldments. Figure 1 illustrates a typical circuit for shielded metal arc welding.įour basic arc welding processes are used in fabricating steel tanks. When the electrode is held so that it is nearly touching the workpiece, the electricity arcs continuously, creating intense heat that melts the electrode and the workpiece, thus welding them together. Arc welding systems consist of: (1)an electrical power source (either AC or DC) equipped with leads for connecting the electricity to the metal being worked on (workpiece) and (2)an electrode holder that is connected to an electrode (or welding rod). Simply put, arc welding is a process in which an electrical arc is created and used as a source of heat to melt and join metals.

Typical Circuit for Shielded Metal Arc Welding Let’s take a quick look at how it works (no safety glasses needed) and then talk about the four different arc welding processes used in steel tank construction. On the good side, arc welding is the essential process that makes the construction of steel tanks possible. Arc welding produces radiation and may burn your eyes (similar to sunburn). The advice back then, not to look directly at the source of the sparks-the welding arc-without proper safety glasses, is still great advice. Those who grew up on the farm likely saw the same kind of sparks when farm machinery was being repaired by welding. Many PE&T readers have seen blue sparks flying from a welder on an overhead bridge.
