Frequently Asked Questions
Why is it called Heliarc welding?
Heliarc welding derives its name from the unique combination of welding techniques and gases used in its process. Developed by Vladimir Pavlecka, Tom Piper, and Russell Meredith for the Northrop Aircraft’s experimental magnesium aircraft in the 1940s, the name “Heliarc” originated from the utilization of a tungsten electrode arc and helium gas as the shielding gas. This innovative welding technique proved to be vital for working with magnesium, as it required a specific method to prevent oxidation and maintain the integrity of the weld joint. Thus, the name Heliarc aptly reflects the key components and gases involved in this pioneering welding process.
What is the process of Heliarc welding?
Heliarc welding is a welding technique that involves the use of an inert gas and tungsten electrodes to join metals. The process begins by passing a high-frequency current through the machine, which heats and melts the metal, transforming it into a liquid state. The tungsten electrodes sustain an electrical arc between the metals, allowing them to be fused together. This method offers a precise and controlled way of welding, as the use of inert gas protects the metal from oxidation and contamination.
What are the 4 types of arc welding?
Arc welding is a versatile and widely used technique in the metal fabrication industry. The four main types of arc welding techniques are Gas Metal Arc Welding (GMAW), Gas Tungsten Arc Welding (GTAW), Shielded Metal Arc Welding (SMAW), and Flux-Coated Arc Welding (FCAW). GMAW, also known as MIG (Metal Inert Gas) welding, uses a continuous wire electrode and a shielding gas to protect the weld metal. GTAW, commonly known as TIG (Tungsten Inert Gas) welding, utilizes a non-consumable tungsten electrode and a shielding gas, providing precise control and high-quality welds. SMAW, or stick welding, employs a consumable electrode coated in flux, which creates a protective gas shield as it burns. FCAW is similar to GMAW, but the consumable electrode is coated in flux, providing additional protection and allowing for welding in outdoor and windy conditions.
When was Heliarc welding invented?
Heliarc welding, also known as gas tungsten arc welding, was invented in 1941 and perfected by Meredith. This groundbreaking welding technique was patented under the name Heliarc welding. With subsequent development of the water-cooled torch at Linde Air Products, gas tungsten arc welding emerged as one of the most significant welding processes in history.
