The Basics of TIG Welding

To understand the basics of TIG welding with its components, definition, and workings, this section presents a solution. Delve into the sub-sections, which briefly introduce the definition of TIG welding, key components of TIG welder, and the way TIG welding works.

Definition of TIG Welding

TIG welding is an electric arc process to heat and melt metal together. It yields high-quality welds with minimal distortion, and is used in aerospace, automotive and nuclear industries. It’s a precise, skilled form of welding.

A tungsten electrode creates the arc. This is shielded by inert gas to prevent oxidation. The filler material is added separately, for greater control. TIG welding is great for thin materials or accurate, precise applications.

Welders use foot pedals to control current, and hold the torch and add filler material with both hands. This slows down the process but produces top-notch results.

A professional welder shared his experience in mastering TIG welding. He said it took years to develop his skills and technique. He practiced on scrap metal pieces and honed his hand-eye coordination with training exercises. His hard work paid off; he became known for creating exceptional TIG welds!

TIG Welder Components

TIG Welding is a delicate process that needs certain components in order to get accurate results. The machine for this type of welding is made up of various parts.

Here are some of the TIG Welding Components along with their descriptions:

• Power Source – A device which creates electric currents for welding.
• Welding Torch – It directs the output from the tungsten electrode to the weld area and controls the start/stop, gas flow, and amperage of the welding.
• Shielding Gas – This shields the weld to avoid oxidation or contamination due to melting and solidification.
• Filler Metal – This works like a patch in places where the metal has melted away or as an extra layer on the existing material.

The tungsten filament for welding must be carefully chosen to match the workpiece material’s conductivity levels without any Oxidation.

Throughout the years, some of the TIG Welding components have been upgraded, such as Plasma Arc Welding. Plasma Arc Welding was introduced in 1957; it utilizes compressed air to produce plasma in an electrical arc by ionizing gas particles through a process that allows high heat conductivity, thus permitting more energy to be sent to harder metals than was initially possible.

How TIG Welders Work

TIG Welders employ electric systems that make arcs between its workpiece and electrode. This welding process melts the metals together, making a strong bond. Control of heat is done with two foot pedals – one for amperage and one for high-frequency current.

Electricity creates heat while shielding gases protect welding surfaces from oxidation. TIG welding has precision, which allows welds of various materials to join without causing harm or distorting the metal. This makes it ideal for thin sheets, stainless steel fabrications, and aerospace components.

The design of TIG welding machines has been updated since A.A. Benardos patented the first method in 1882. It was US spark plug manufacturers who modified them for their factories in the 1940s.
