Welding gas, also known as shielding gas, is used extensively in welding processes like Gas Metal Arc Welding (GMAW) & Gas Tungsten Arc Welding (GTAW), etc., mainly to protect welds from atmospheric contaminants like oxygen, nitrogen, & water vapor, among others. There exist several types of welding gases like CO2, Argon, Oxygen, Hydrogen, Acetylene, & Helium, among others, used either in their pure forms or in a combination of two, like argon-helium, argon-carbon dioxide, argon-oxygen, etc. With the flourishing building & construction, metal manufacturing, automotive, & aerospace sectors globally, the welding industry is witnessing an unprecedented boom, as welding is one of the crucial processes in these end-user verticals.

Consequently, there is an ever-growing demand for welding gases to attain high-quality welds in these industries. Considering their growing production & demand, a recent research report published by MarkNtel Advisors has cited that the Global Welding Gas Market is set to record around 5.2% CAGR during 2022-27. Rising urbanization & industrialization, the increasing number of residential & commercial development projects, especially in emerging countries, and the mounting use of gases in metal fabrication & manufacturing welding processes are the key aspects projected to drive the industry in the forecast years.

Different Gases Used in Welding Processes

  • Carbon Dioxide
  • Argon
  • Hydrogen
  • Oxygen
  • Others (Helium, Acetylene, etc.)

Among all the gases, argon is the most prominent shielding gas used in welding processes, especially in the metal manufacturing & fabrication sector. Due to its inert nature, it creates a barrier between welds & contaminants in the environment (Atmospheric Oxygen, Nitrogen, CO2) and offers great stabilization on electric arcs in metal fabrication processes. In addition, properties like the excellent resistance to heat cracking and high thermal conductivity of argon gas make it ideal for the stainless steel welding application.

Geographical Landscape of the Shielding Gas Industry

Countries like China, Japan, & India are massively investing in infrastructure development projects and witnessing significant industrial expansions, improving economic conditions, & rapid urbanization. These aspects indicate the burgeoning use of welding processes across these countries and, consequently, the mounting utilization of welding gases across Asia-Pacific. Moreover, the massive automotive sector, thriving electronic, heavy engineering, & metal fabrication industries, and an increasing number of housing facilities in these countries are also contributing to the surging demand for welding gases across the region, thereby creating remunerative prospects for gas manufacturers to expand their production & distribution capacities in order to meet the ever-growing end-user requirements.

Final Words

Welding is an integral part of most end-user industries like metal manufacturing & fabrication, building & construction, aerospace & defense, and automotive, which are expanding at a rapid pace globally. Likewise, gases are always in demand to facilitate the welding process & ensure that welds are of the highest possible quality.

Moreover, efforts are being made toward achieving greater levels of reliability, high quality, & automation in welding, and there’s a growing need for lower manufacturing costs & enhanced productivity in the welding industry. Hence, these trends indicate that the global welding gas market is set to witness notable growth in the coming years and create a pool of profitable prospects for the leading gas manufacturers operating in the industry.
