term used is “gas welding.” Oxyacetylene and oxy-MAPP (methylacetylenepropadiene) welding are two types of gas-welding processes. Both require a gas-fueled torch to raise the temperature of two similar pieces of metal to the fusion point that allows them to flow together. A filler rod is used to deposit additional metal as necessary to merge the two base materials. The gas and oxygen must
