For top expertise and products in welding equipment, look no further than Red-D-Arc Welderentals. This equipment can be used for different types of welding, including such common examples as oxy-acetylene welding and arc welding. These processes are generally used for the same purposes, but they have very important differences.
A recent blog entry by Red-D-Arc examines the differences between oxy-acetylene and arc welding, including respective pros and cons.
Gas versus electric arcs
Also known as gas welding, oxy-acetylene welding uses two sources of gas, oxygen and a combustible fuel. Pumping both through a torch, mixing them, and blasting them through a nozzle creates a jet of combustible gas. Arc welding use the power of an electric arc to melt conductive metals quickly: a current is placed through a circuit, with one end on a welding torch and the other on the workpiece. When the two come close together, the circuit completes in a high-energy arc.
One of the biggest differences is temperature. Oxyfuel welding creates flames as hot as 3,600 degrees Celsius, more than enough to melt steel for joints. But arc welding generates even more heat, and this is often preferable. Lower heat can create a large heat-affected zone, according to Red-D-Arc, which can lead to more area of the steel becoming compromised. Other criteria to consider when weighing these options:
