oxyfuel safety

The X's and O's of oxyfuel

January 15, 2010

By:

If properly used and well-maintained, this equipment can cut, heat, and weld metals safely. But damaged, worn, or improperly handled equipment can lead to safety hazards such as fire and explosions that can cause serious injury or death. To know how to handle and care for the equipment and devices found in oxyfuel cutting and welding, you have to first be familiar with them and the kind of care they need.

Efficient shielding gas supply methods

February 26, 2004

By:

The introduction of gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW) in the 1940s changed the way metals were joined. The automation of these processes meant the gas supply system also had to be automated to achieve optimal productivity.

Choosing the right oxyfuel gas and supply system

November 6, 2003

By:

Mixing oxygen with fuel gases for brazing, cutting, heating, and welding metal has been around since the early 1900s. Oxyfuel processes have remained in use over the years despite the introduction of other metal fabrication processes, such as arc welding, plasma cutting, and laser materials processing. Finding the most economical method for supplying oxyfuel gases requires a basic understanding of the process.

Efficient use of compressed gases can increase productivity

August 28, 2003

By:

The metal fabrication industry has used compressed gases for more than one hundred years. Oxy-fuel cutting and welding have existed since the beginning of the 20th century. The more automatic welding processes, such as gas metal arc welding (GMAW) and gas tungsten arc welding (GTAW), began as early as 1920.
