Course Description:

Gas Tungsten Arc Welding (GTAW), also known as tungsten inert gas (TIG) welding is a process that produces an electric arc maintained between a non-consumable tungsten electrode and the part to be welded. The heat-affected zone, the molten metal, and the tungsten electrode are all shielded from atmospheric contamination by a blanket of inert gas fed though the GTAW torch. Inert gas (usually Argon) is inactive or deficient in active chemical properties. The  shielding gas serves to blanket the weld and exclude the active properties in the surrounding air. Inert gas such Argon and Helium, do not chemically react or combine with other gases. They pose no odor and are transparent, permitting the welder maximum visibility of the arc. In some instances Hydrogen gas may be added to enhance travel speeds.

The GTAW process can produce temperature of up to 35,000^O F (19,426^O C). The torch contributes heat only to the work piece. If filler metal is required to make the weld, it may be added manually in the same manner as it is added in the oxyacetylene welding process, or in other situations may be added using a cold wire feeder. GTAW is used to weld steel, stainless steel, nickel alloys such as Monel and Inconel, titanium, aluminum, magnesium, copper, brass, bronze and even gold. GTAW can also weld dissimilar metals to one another such as cooper to brass and stainless steel to mild steel.

Pre-Requisite:   

The trainees must have experience in Shielded Metal Arch Welding (SMAW) using various electrodes.

Course Description

Oxyacetylene welding involves placing two pieces of metal (usually carbon steel) close together and heating the junction until it melts, and the base metal flows together. Something additional metal, called filler metal is added in the form of a welding rod which is added to the puddle of molten base metal. Filler metal is usually added to make up any gaps in the weld.

Oxyacetylene welding used to be the most common methods of welding steel before the invention of the arc welder. This method of welding has mostly fallen out of favor for manufacturing because the relatively low heating rate (relative to an arc welder) can cause warping and thermal damage to a wide area around the weld. Oxyacetylene welding is still often used in small shops and by artist, but is not generally used in manufactured goods because of the lower  weld quality.

Oxyacetylene welding is used almost exclusively for the securing of carbon steel, but is also used frequently by jewelers for welding gold and silver. Some metals such a aluminum and titanium cannot be welded using an oxyacetylene torch and must be welded using GTAW (TIG) or GMAW (MIG) techniques.

Oxygen and acetylene combine into oxyacetylene to form the hottest burning and most widely available combination of gasses. MAPP gas burns at a paltry ˜3000 degrees centigrade, while Oxyacetylene will manage 5500 degrees centigrade at stoichiometric ratios.

Course Description:

Pipe fitting is the occupation of installing or repairing piping or tubing system that convey liquid,gas, and occasionally solid materials. This work involves selecting and preparing pipe or tubing, joining it together by various means, and the location and repair of leaks.

Steel Pipe (or black iron pipe) was once the most popular choice for supply of water and flammable gases. Steel pipe is still used in many homes and businesses to convey natural gas or propane fuel, and is a popular choice in fire sprinkler systems due to its high heat resistance. In commercial buildings, steel pipe is used to convey heating or cooling water to heat exchangers, air handlers, variable air volume (VAV) devices, or other HVAC equipment.

Pipe fitter is a trades-person who installs, assembles, fabricates, maintains and repairs mechanical piping systems. Pipefitters usually begin as helpers or apprentices. Journeyman pipe-fitters deal with industrial/commercial/marine piping and heating/cooling system. Typical industrial process pipe is under high pressure, which requires metals such as carbon steel, stainless steel, and many different alloy metals fused together through precise cutting, threading, grooving (Victaulic).

After completing the course, the trainees will be familiar with:

• Blueprint reading/reading isometric sketches
• Detailing
• Layout/flanges and elbow fit-up
• Supports and hanger Installation
• Pipe Threading
• Pipe grinding
• Mechanical pipe cutting and grooving
• Gas arc cutting
• Safety precautions in pipefitting
