Oxy-Fuel Welding and Processes

Oxy-fuel welding (commonly called oxyacetylene welding, oxy welding, or gas welding in the U.S.) and oxy-fuel cutting are processes that use fuel gases and oxygen to weld and cut metals, respectively. In oxy-fuel welding, a welding torch is used to weld metals. Welding metal results when two pieces are heated to a temperature that produces a shared pool of molten metal. The molten pool is generally supplied with additional metal called filler. Filler material depends upon the metals to be welded. In oxy-fuel cutting, a cutting torch is used to heat metal to kindling temperature. A stream of oxygen then trained on the metal combines with the metal which then flows out of the cut (kerf) as an oxide slag

SMAW -Shielded Metal Arc Welding

The Shielded Metal Arc Welding process (SMAW), commonly referred to as stick welding, derives the heat for welding from an electric arc established between a consumable stick electrode and the part to be welded. The stick electrode is clamped in an electrode holder which is connected to the stick welder by a power cable. The current produced by the stick welder for welding can AC or DC, depending on the model.

GMAW Gas Metal Arc Welding

Gas-Metal-Arc Welding (GMAW) evolved from CAW when it was realized that a consumable electrode - eliminating any need for a welding rod, could replace the carbon electrode. To reduce oxidation, the electrode wire is coated with materials such as fluorides, oxides, carbonates, metal alloys, and binders to stabilize the arc, to produce gases to shield the weld from oxygen and atmospheric contaminants, and to introduce metal alloy to weld. GMAW is used principally with nickel and ferrous base metals

GTAW Gas Tungsten Arc Welding

GTAW Welding

Gas Tungsten Arc Welding (GTAW) is frequently referred to as TIG welding. TIG welding is a commonly used high quality welding process. TIG welding has become a popular choice of welding processes when high quality, precision welding is required.

In TIG welding an arc is formed between a nonconsumable tungsten electrode and the metal being welded. Gas is fed through the torch to shield the electrode and molten weld pool. If filler wire is used, it is added to the weld pool separately.
