TIG welding is a versatile metal fabrication method that is used for a variety of purposes, such as precision welds, intricate shapes, and high-quality materials. The success of this type of welding method is demonstrated by the fact that it is used in multiple industries, including the automotive, aerospace, agricultural, and medical fields.
According to the American Welding Society, TIG welding is the most common type of welding process used in the United States, accounting for over 41% of the total welding jobs. Lift Tig welding is a specialized form of TIG welding that is designed to facilitate the welding of thin sheets of metal, allowing for high-quality welds in a fraction of the time traditionally required. It works by creating a short electrical arc between the material being welded and a lift tig electrode.
This arc creates an intense heat that melts the material, allowing it to be welded together. With Lift Tig welding, welders can produce high quality welds at a rate of up to 24 times faster compared to traditional TIG welding. In addition, due to the precision of the process, Lift Tig welding can reduce the necessary labor costs associated with traditional TIG welding.
What is Lift TIG Welding?
Lift TIG welding is a process that combines both shielded and TIG welding to provide an efficient and reliable welding method.This welding process utilizes a high-frequency alternating current to create an arc, during which the filler metal and base material are heated. This arc is then modulated to better define the weld, producing a cleaner and more durable weld. This technique is often used within the aerospace and automotive industries, as well as in the development of medical devices, due to its efficient and reliable nature.
Description of The Process
The Lift TIG Welding process begins with the use of an inert argon-based shielding gas, similar to that used in regular TIG Welding. This gas is used to protect the weld from oxidation and ensure the quality of the weld. The weld also requires an electrode that is negative, typically made from either an alloy of zirconium, thoriated tungsten, or lanthanated tungsten.The arc that is created is then pulsed, or modulated, using a high-frequency current. This serves to control the heat of the weld and further define the depth, size, and shape of the weld itself.
The intensity of the pulse should be configured so that it is not too high, as a high-frequency current could cause the element to melt and cause slag to build up on the surface of the weld.
Benefits of Lift TIG Welding
- High Strength and Durability – The process of Lift TIG Welding creates a strong and durable bond between the weld and the base metal.
This increases the strength and durability of the weld, making it suitable for welds that require high structural integrity.
- Smooth Finish – Lift TIG Welding provides a smoother finish than standard TIG Welding. The pulsing of the arc produces a much more uniform and neat look, making this process ideal for components that need to have a polished finish.
- High Versatility and Efficiency – Lift TIG Welding is able to accommodate many different types of metals and materials, making it highly versatile. Additionally, the process itself is relatively fast and efficient, making it suitable for larger production runs.
- Clean Welds – Lift TIG Welding produces welds that are free of contaminants. This is due to the shielding gas that is used, as well as the pulsing of the arc, which helps to better control the heat of the weld and prevent inconsistencies.
