Safety Should be Thought No. 1 When Welding
With all welding, cutting and metal removal processes, you should keep your head out of the fume plume and use local exhaust and ventilation or individual respiratory equipment. Numerous chemicals in use during welding have exposure limits, including: Aluminum fume, arsenic, calcium oxide, cobalt, copper fume, lead, phosphorous, zinc oxide and many more.
Gas Welding | Article about Gas Welding by The Free …
a process of welding through the spot melting of a metal by the flame of a gas-fed welding torch. For higher flame temperature, a mixture of a gaseous fuel and industrially pure oxygen is used. Gas welding is like brazing in that it''s done with a torch, but instead of using molten bronze to "glue" metal parts together, welding generates enough heat to actually melt the metal on each side of
Welding, Cutting, and Brazing Checklist
56. Have employees who are designated to operate arc welding equipment been properly instructed and qualified? .254(a)(3) 57. Are open-circuit (no-load) voltages of arc welding and cutting machines as low as possible, consistent with satisfactory welding 58.
In fusion welding processes, electric arc is the main source of the heat, required for melting of the metal. Electric arc forms when electric current is made to pass between two electrodes separated by a gap.Flow of current across the gap is maintained by the

Acetylene - Wikipedia
Acetylene (systematic name: ethyne) is the chemical compound with the formula C2H2. It is a hydrocarbon and the simplest alkyne. This colorless gas (lower hydrocarbons are generally gaseous in nature) is widely used as a fuel and a chemical building block. It is unstable in its pure form and thus is usually handled as a solution. Pure
