Different Types of Welding joints


In gas welding, the gas fire is used for melting and warming the connecting surfaces along with also the filler rod. Gas welding is carried out by burning a combustible gas with oxygen or air at a concentrated fire of elevated temperatures.

Most significant combustible gas that gives maximum fever is acetylene. Hydrogen can also be utilized in gas welding of low melting point metals like aluminum. Infection oxyacetylene flame is all about 3200 C and is now enough to weld steel. If you want to learn more about welding joints then you can explore www.skfitting.com/fittings.htm.

Acetylene is a compound of hydrogen and carbon (C2H2) comprising 92.3 percent carbon and 7.7 percent hydrogen by weight. It’s a colorless and has a pleasant and renowned odor. Sometimes oxygen is a colorless, odorless and tasteless gas. Usage of pure oxygen levels up responses and raises fire temperature.


Arc welding is most widely used way of joining metal components. Inside this, the supply of warmth is an electrical arc. An arc is generated involving an anode (positive pole of direct current power source) and the cathode (negative pole). Arc welding is carried out by creating an arc involving the job to be welded as well as also the suggestion of the electrode.

After two conductors of the electrical current are attracted together make electric contact, and then split, an electrical arc is shaped. A substantial resistance to this flow of the present is therefore released; the electrode suggestions are increased to elevated temperature because of an air gap between these.
