Gas pressure welding
This page introduces the principles of gas pressure welding, a method often used for joining steel building frames.
This method is often used to join steel frames for buildings. The joining surfaces of the base materials are pressed against each other and the area is heated with acetylene gas and oxygen. When the base materials heat up and start melting, they are further pressed against each other. Impurities in the joining surfaces are pushed out and the surfaces are joined.
