Uses & Applications of Acetylene Gas by Industry

Automotive & Transportation Equipment

Acetylene is used as a key component in low pressure carburizing. It provides the precise carbon source automotive manufacturers need to create a strong, wear-resistance surface layer on steel parts.

Welding & Metal Fabrication

Acetylene offers the hottest flame temperature of all commercially available fuel gases, making it an ideal atmosphere for oxy-fuel welding and cutting, as well as, brazing applications.
