Arc and gas welding stainless steel are two of the oldest types of welding processes. Welding processes are often classified according to the energy source and other more innovative types would include a laser, a friction, an electron beam and an ultrasound. However, arc and gas or oxy-fuel welding has been around for centuries now. Even with the introduction of robot welding this modern age, arc and gas welding continue to be quite useful for many industries.
Advantages of Gas Welding Stainless Steel over Arc Welding
Gas welding stainless steel or also known as oxy-fuel welding does not require electric power supply unlike arc welding. It produces flame with the mixture of fuel gases and oxygen usually acetylene and oxygen. The flame’s temperature is adjusted with the mixture of fuel gas and oxygen to make a good welding flame. Other fuel gases include propylene, gasoline, hydrogen and MAPP or Methylacetylene-propadiene or MPS mixed with (LPG) liquefied petroleum gas. Acetylene is known to be more expensive compared to the other fuel gasses. But since oxygen and other fuel gasses are portable, it makes it very convenient for many to choose gas welding stainless steel in remote areas. On the other hand, without power supply, arc welding becomes impossible. This is the biggest advantage of gas welding over arc welding.
Disadvantages of Gas Welding Stainless Steel over Arc Welding
While the common issue of arc welding is focused on cost of constant power supply, gas welding has its own disadvantages too. Safety and protection are two of the main issues in gas welding. Fuel gasses are combustible and require a lot of care and proper use and storage. Oxygen tanks are also dangerous and must be placed properly with valves secured in place. Oxygen tanks do not burst but they swing around. And with the pressure, they can hurt people seriously.
Issues of chemical exposure are also relevant when it comes to gas welding. Serious side effects include neurological problems, lung and heart disorders. It is necessary to use the protective gears at all times and observe safety measures all the way. Finally, welding quality of arc welding is better compared to gas welding. The different processes of arc welding and innovations thereof contribute to the enhanced welding quality. In addition, the speed in completing a welding job is definitely faster with arc welding compared to gas welding stainless steel.
Choosing Between Gas Welding Stainless Steel and Arc Welding
Definitely if you simply needed something to be done without any urgency but with budget constraints, gas welding stainless steel is preferable. This also means that there are no quality specifications that only arc welding can accomplish. This is why welding of pipe and tubes are still done with gas welding as well as repair work and fabrication. There are also instances when only gas welding is possible especially in construction work in remote places where electricity is controlled, limited or not available. However, if time is of the essence, cost is not an issue and quality is a primary consideration then one must consider using arc welding instead or a combination of arc and gas welding stainless steel.
