Welding and Cutting

Gases Used in Metal Welding and Cutting

The gases used in metal welding and cutting need to be highly pure to ensure the best weld and cut quality, minimize waste, and improve productivity. The choice of cutting method depends on various factors, such as laser cutting, plasma cutting, or oxy-fuel cutting, each with its own advantages.

Laser Welding and Cutting Gases

Laser cutting is a highly precise method using laser beams to melt materials. Protective gases are used to shield the lens, cool the edges, and remove molten metal and oxides.

  • Carbon steel and low-alloy steel: Oxygen and Nitrogen.
  • Stainless steel, aluminum, and alloys: Nitrogen.
  • Magnesium, titanium, and reactive materials: Argon.

Plasma Cutting Gases

Plasma cutting involves plasma arc jets created by ionized gas at temperatures of around 20,000°C, melting the metal and removing it from the cut. Typical plasma gases include Argon, Helium, Nitrogen, and Hydrogen, used either individually or in mixtures.

Oxy-Fuel Cutting Gases

Various fuel gases are available, including acetylene, ethylene, hydrogen, methane, propane, propylene, and their mixtures. Each gas offers unique properties, with acetylene, propane, and propylene being the most common.
