What Is Oxy Acetylene Welding?
Oxy-Acetylene gas welding is technique of welding metallic pieces through heat in this case a mixture of oxygen and acetylene gas is burned and is then made to contact the metal pieces to be melted with the impact of heat the metals melt and then they fuse into each other finally they are left for cooling and a joint is produced. The important components of this type of welding are oxygen and acetylene cylinders, oxygen cylinders are usually painted green they contain compressed oxygen with a pressure of roughly 2200 psig. If Oxygen comes into contact with oil or grease, it will burst into flame so it is not recommended to use oil or grease on cylinder valves or regulators. Even the hand and gloves of the user should be free of grease and oil. The other important part is acetylene cylinder which contains compressed acetylene up to a pressure of 250 psig however a great care is to be taken whenever one is using this gas if the pressure of release is exceeded above 15 psig; it could be v
