TIG Welding (GTAW)

TIG Welding Fabrication

Tungsten Inert Gas welding (TIG Welding) uses the heat of an electric arc between a tungsten electrode and the base metal. A separate welding filler rod is fed into the molten base metal, if needed. A shielding gas flows around the arc to keep away air and other harmful materials

TIG welding fabrication is also known as GTAW or Heliarc Welding. A TIG welder is generally more advanced than any other type of welder due to the difficulty of the process. It takes experience and high precision since both hands are used during this welding process. During welding, one hand holds the TIG torch that creates the arc, and the other hand is used to add the filler metal to the weld joint. This creates more control over the other welding processes out there and constructs strong precise welds.

By using a non-consumable electrode, called the tungsten electrode, a strong and high quality weld is produced. Tungsten is a slightly radioactive, hard but brittle metal. The unique properties of tungsten allows for welding with a hotter arc than the actual melting point of the tungsten. TIG welding fabrication uses the heat of an electric arc between a tungsten electrode and the base metal, shielding gas, and filler metal. A separate welding filler rod is fed by hand into the arc and melted. A shielding gas flows around the arc to keep away air and other harmful materials.

MIG Welding (GMAW)

DMig welding, also known as GMAW(Gas Metal Arc Welding) or wire welding, is not as common as stick welding, but it’s use is on the rise. A few reasons for the increase in it’s popularity could be due to its fast learning curve, a quicker process than the other major welding types, produces less slag for easy welding and cleaning, and continuous welds via wire feeding mechanism. To prevent contamination the welding area of the working material is covered with argon gas, preserving a quality weld.

MIG Welding Fabrication

MIG welding fabrication stands for Metal Inert Gas Welding, also known as Gas Metal Arc (GMA) or Gas Metal Arc Welding (GMAW). Generally the name differs based on the type of gas being used, Inert Gas or Non-Inert Gas. MIG welding fabrication was developed in the 1940s and is now used in high production shops. MIG welding does not require as much skill as other welding processes since it is semi-automated. This type of welding creates clean weldments with very little smoke. It is fast and has a low skill level to operate. It’s also great for spot and tack welding. MIG welding fabricators use a trigger to dispense the wire that is fed from a spool to the weld joint. Some say the wire is very similar to a bicycle break cable since the wire goes through a liner, which contains a gas that is also fed through the cable to the point of the arc.

MIG welding fabrication uses electricity to produce heat, an electrode to fill the weld joint, and shielding gas which protects the weld from the surrounding air. The small electrode or wire is fed continuously and semi-automatically, while the welder controls the welding. There are four ways of transferring the wire to the weld joint, which include: Short Circuit, Globular, Spray, and Pulsed Spray.

• Short Circuit Transfer is used at a lower voltage and occurs when the wire arcs and comes in contact with the metal in short circuits. When the wire meets the heated metal, it puddles. With several short circuits, it sounds like several fast crackles.
• Globular Transfer is very similar to the short circuit transfer as it occurs when the wire arcs when it contact with the metal, but the wire melts longer and creates a blob instead of a puddle. The sound of globular transfer has a popping sound every few seconds.
• Spray Transfer requires high voltage, and the transfer is a spray. The wire sprays or mists to the metal when it arcs. The sound is of spray transfer is a hiss.
• Pulsed Spray Transfer is utilized with special equipment which pulsates the voltage several times a second. This effect allows an arc between spray transfer, to globular transfer, and then back to spray transfer repeatedly.
