What is flashback in gas welding. 2-94, Safety in Welding, Cutting, and Allied Processes. What causes flashback in gas welding? Flashbacks are commonly caused by a reverse flow of oxygen into the fuel gas hose (or fuel into the oxygen hose), producing an explosive mixture within the hose. When a flammable mixture of fuel gas and oxygen or air is present in a gas line upstream of a welding or cutting blowpipe, flame can travel By understanding the difference between flashback and burnback, you can protect yourself from injury when welding. Oxyfuel Safety – Flashback Arrestors flashback arrestor is a safety device that prevents the propagation of a flame upstream reducing the volume of gases available at the tip or nozzle of an oxyacetylene To halt a flashback or reverse the flow of gas, dry flashback arrestors typically use a mix of safety components.
