There are a few commonly used welding process. The top used are shielded metal and arc welding.
SMAW stands for shielded metal arc welding. The rectifier used in the welding machines must be referring to this type welding.
A base metal is also called the Parent metal. It is that metal in the welding practice that has been cut by the various forms of cutting, then prepared and is to be welded. Welding is performed to join one section of the base metal to another section of base metal by means of the various welding processes, e.g. SMAW(Shielded Metal Arc Welding) where welding welding rods are used, GTAW(Gas Tungsten Arc Welding) where Tig wire is used, FCAW(Flux Cored Arc Welding) etc. The welding rods, the TIG wires etc are called the filler metals, for they fill the weld gaps by depositing their molten-state weld metals.
For welding 8 mm thickness metals, common methods include MIG (Metal Inert Gas) welding, TIG (Tungsten Inert Gas) welding, and stick welding (SMAW - Shielded Metal Arc Welding). The choice depends on the type of metal and specific requirements.
Steel is such a commonly used metal that almost any welding machine can accommodate it. Some are better than others though. Steel is usually welded with either sick welding, or wire welding (gas shielded or flux core)
Covered electrodes are vital to the process of shielded metal arc welding. The covered electrode is one of four types of filler metal used when creating a joint from two pieces of metal.
Any electrode holder that will accommodate the size of rod can be used. Twin Carbon Arc Welding requires a specific holder. Air Carbon Arc Gouging requires a special holder that also supplies a stream of air.
It is arc welding process using a spool of wire that is fed to the material by an electric motor. Different from shielded metal arc welding which uses consumable welding electrodes with a covering of flux to assist and protect the weld. The MIG uses an inert gas (IG) to keep impurities from the welding point. The technical term for MIG is GMAW (gas metal arc welding), this is because most of the time an inert gas is not used, a mixed gas is more likely. Ex. 90-10 Ar-CO2
When two pieces of metal are joined by welding they become one as if they were made that way. Welding replaced riveting and reduced the amount of metal used while producing a stronger joint.
MONEL alloy 400 is readily joined by conventional processes and procedures. Most of the conventional welding processes may be used to join MONEL alloy 400 to itself or dissimilar alloys. The choice of welding product is dependent upon the materials being joined and the environment to which they will be exposed. For shielded metal arc welding (SMAW), MONEL Welding Electrode 190 is used to deposit near-matching composition weldments. For some applications, Nickel Welding Electrode 141, INCO-WELD A Welding Electrode, or INCONEL Welding Electrode 112 may be preferred. Properties of weldments deposited with MONEL Welding Electrode 190 between two sections of MONEL alloy 400 plate and between sections of alloy 400 and carbon steel plate are shown in Tables 20 and 21. For gas tungsten arc welding (GTAW) and gas metal arc welding (GMAW), MONEL Filler Metal 60 is used to deposit near-matching composition weldments. For some applications, Nickel Filler Metal 61 or INCONEL Filler Metal 625 may be preferred. These same filler metals may be used for submerged arc welding (SAW). INCOFLUX 5 is used with MONEL Filler Metal 60. INCOFLUX 6 is used with Nickel Filler Metal 61. INCONEL Filler Metal 625 is used with INCOFLUX 7.
There are a considerable number of welding processes that cover a vast range of metals and some nonmetals in most industries and applications. An excellent resource for welding information is The American Welding Society (AWS.org). A short list of the most common processes are: Oxygen Fuel Gas (OFG) which includes welding and cutting equipment where oxygen is mixed with a fuel gas such as acetylene, propane, etc. and a torch is used. Shielded Metal Arc (SMAW) sometimes called "Stick Rod" welding. This is a manual process that uses a flux covered wire electrode that melts during welding to form the filler metal. Gas Metal Arc Welding (GMAW) sometimes called "MIG" (for Metal Inert Gas) which is a semi automatic process that uses a bare or flux cored wire that is delivered by a spool drive during welding. Gas Tungsten Arc Welding (GTAW) sometimes called "TIG" (for Tungsten Inert Gas) or Heiliarc (trade name by the Lindy corp.) which uses a non consumable Tungsten electrode in an inert gas shielded gas torch. The Tungsten's produces the heat (via an electric current) and filler metal is added by "dipping" the tip of a bare wire to the weld puddle. The list goes on to include things like Electron Beam Welding , Plasma Arc Welding / Cutting, Friction Welding, Explosion Welding. Microwave Welding, Plastic Welding, etc.. Welding is used on everything from auto mufflers to space vehicles and medical instruments.
