Argon-Hydrogen Blends

Welding processes rely on several gases to provide shielding and heat the metal. Combining two or more of these materials can enhance the project’s results by maximizing the properties of each substance. 

A mixture of argon and hydrogen is one of the more commonly applied welding gas blends. Argon provides arc stability and a continuous metal transfer from the weld pool’s electrode. It also delivers excellent shielding in tungsten inert gas applications. 

Adding hydrogen to argon boosts the welding speed and ensures deeper penetration without impacting the weld’s width, resulting in a higher depth-to-width ratio. The higher heat input also increases the cross-sectional area. 

A Meritus Gas Partners supplier is your one-stop headquarters for high-quality argon-hydrogen welding gas to add value to your business operations. You’ll also receive excellent service to maximize your customer experience. 

Argon-Hydrogen Gas Cost and Availability

Argon gas production is increasing to meet the rising demand. While hydrogen is readily available, as it has numerous essential applications, not all distributors fill hydrogen or hydrogen mixtures. The mixture’s cost varies depending on the cylinder size, the percentage of each gas in the blend and other factors. 

Uses and Applications of Argon-Hydrogen Welding and Shielding Gas

These blends consist primarily of argon gas. Altering the hydrogen content impacts the mixture’s performance. Examples of the more common combinations include:

This blend is a good choice for manual welding applications for materials with a thickness of 1/16 inches or less. It also performs well for gas tungsten arc welding of austenitic stainless steel and as a back purge shielding inside the weld.

If your tasks include welding butt joints on stainless steel workpieces, this combination can do the job up to 50% faster than argon alone. The mixture is compatible with any stainless steel thickness level.

Ramping up the hydrogen content enables the combination to serve as an effective plasma gas. Use it when cutting stainless steel and aluminum, plasma arc gauging and other applications requiring excellent face appearance and cut quality.

Argon-Hydrogen Shielding Gas Safety

While argon and hydrogen are inert gases — meaning they do not react with other substances to form compounds — hydrogen is highly flammable. Keep cylinders containing the mixture away from other combustible materials or anything that could cause a spark. 

This blend is also an asphyxiant that can cause suffocation by displacing oxygen. Use and store the gas in a well-ventilated area.
