Carbon arc welding is the first electric welding process invented by russian inventor Nikolay Benardos in 1881. In this welding method, an electrode made up of carbon or graphite is used to initiate an electric arc. The welding i…
A welding electrode is a piece of wire or rod used in the welding process for joining the metals. The welding electrode is connected to the welding machine, carrying welding current, and establishes an electric arc to fuse the me…
The power supply used for electric welding can be either direct current (dc) or alternating current (ac). In this article let us see the difference between ac and dc welding machines. AC Welding : An ac welding set or machine …
The process by which two metal or non-metal pieces are joined by heating them to the melting point is known as Welding. Electric welding is a process in which two metal pieces are joined together by the heat produced due to the f…
Resistance welding is a type of electric welding in which heat produced to weld the two metal pieces will be due to the resistance offered to the flow of current by the two metal pieces at the point of joint. In this article let …
The process of induction heating is based on the principle of transformer working. The material to be heated make use of induced currents due to changing electric current in the primary. Generally, there are two types of inductio…
Induction heating is a type of electric heating in which currents induced in the material by electromagnetic action are used to heat it. It is a contactless electric heating method in which the material will be heated without mak…
