Comparison between oxyhydrogen welding and Oxyacetylene welding |
||
Comparison |
Oxyhydrogen welding |
Oxyacetylene welding |
Working features |
Only water and electricity to produce oxyhydrogen gas on demand |
Oxyacetylene welding is high pressure oxygen cylinder and acetylene cylinder |
Welding quality |
1. High temperature, flame temperature can be 2800 celsius 2. Flame concentration, no flame spread 3. The solder joints are smooth and full |
1. Low flame temperature, easy to cause virtual welding.This will affects the product quality. 2. Flame spread, easy to cause the adjacent varnished wire depainting and lead to poor insulation |
Working efficiency |
1. Quick welding speed, high temperature will increase the welding efficiency 2. High energy, hydrogen heat value is 34000 kilocalorie, 3. No need to remove the copper varnish coating |
1. Low flame temperature, low relative welding efficiency 2. Gas cylinder need keep in storage and carry, cost labor-hour. 3. If the gas company doesn't send gas in time, it will seriously affect the production 4. Need to remove the copper coating.It costs more time. |
Safety |
1. No gas cylinders 2. No leakage and explosion 3. No poison 4. No high pressure 5. No thermal radiation. 6. Built-in anti-fire protecting device |
1. Gas cylinders, with a risk of leakage and explosion 2. Gas leak will lead to poisoning or death |
Cost |
1. Water cost is low, only some electricity and no other fuel cost 2. energy saving 40%-60% |
Acetylene cost is high per cbm, so more fuel gas cost and high welding cost |
Health and environment |
1. Zero carbon emissions processes. 2. Water as a source for welding and only water vapor after combustion. 3. Non-toxic to the workers and eco-friendly to the environment. |
1. Oxyacetylene combustion produces toxic gases such as carbon monoxide, carbon dioxide and sulfur dioxide. 2. Harmful to the workers and not friendly to the environment. |
