Comparison between oxyhydrogen welding and Oxyacetylene welding | ||||
Comparison | Oxyhydrogen welding | Oxyacetylene welding | ||
Working features | Only water and electricity to producel oxyhydrogen gas on demand | Oxyacetylene welding is high pressure oxygen cylinder and acetylene cylinder | ||
Safety | No gas cylinders, no leakage and explosion,built-in anti-fire protecting device | Gas cylinders, with a risk of leakage and explosion | ||
Cost | Water cost is low, only some electricity and no fuel cost; energy saving 40%-60% | Acetylene cost is high per cbm, so more fuel gas cost and high welding cost | ||
Health and environment | Zero carbon emissions processes. Water as a source for welding and only water vapor after combustion. Non-toxic to the workers and eco-friendly to the environment. | Oxyacetylene combustion produces toxic gases such as carbon monoxide, carbon dioxide and sulfur dioxide. Hamful to the workers and not friendly to the environment. | ||
