Stick or MSAW welding
Advantage Fabricated Metals performs a number of welding processes. The two most common welding processes we use include TIG, an acronym for Tungsten Inert Gas welding and MIG, an acronym for Metal Inert Gas welding. TIG is also referred to as GTAW (Gas T ungsten Arc Welding) and Heliarc®. MIG also is referred to as GMAW (Gas Metal Arc Welding). We also provide stick or MSAW welding.
Shielded Metal Arc Welding (SMAW) is frequently referred to as "stick" or "covered electrode" welding. Stick welding is among the most widely used welding processes.
The flux covering on the electrode melts during welding. This forms the gas and slag to shield the arc and molten weld pool. The slag must be chipped off the weld bead after welding. The flux also provides a method of adding scavengers, deoxidizers, and alloying elements to the weld metal.
The process allows only short lengths of weld to be produced before a new electrode needs to be inserted in the holder. Weld penetration is low and the quality of the weld deposit is highly dependent on the skill of the welder.
Process characteristics of Shielded Metal Arc Welding (SMAW/Stick)
During the SMAW welding process the arc is established, the flux coating on the rod disintegrates and then forms a gas that shields the weld from the atmosphere. The slag that is produced by the flux coating prevents the weld metal from oxidizing.
Equipment required to perform the SMAW welding process includes a constant current power source that supplies the power to the consumable rod electrode.
The illustration below shows these four common welded joints.
Flux-coated electrodes are available in many core wire diameters and lengths. Matching the electrode properties to the base materials as a general rule for choosing the type of electrode. Available electrodes types include aluminum bronze, bronze, mild steel, nickel, and stainless steel.
Materials commonly welded using the SMAW process include mild steel, cast iron, and stainless steel.
