Spot Welding Machine Working Principle

Today we will learn about resistance welding principle types application advantages and disadvantages.

Spot welding machine working principle.

Basic idea of welding transformer a welding transformer is a step down transformer that has thin primary winding with a large number of turns and its secondary has more area of cross section and less number of turns ensuring less voltage and very high current in the secondary. The process uses two shaped copper alloy electrodes to concentrate welding current into a small spot and to simultaneously clamp the sheets. The working principle of resistance welding is the generation of heat because of electric resistance. This is glowing electrical discharge among two electrodes throughout ionized gas.

The resistance welding such as seam spot protection works on the same principle. Projection welding is one of the types of resistance welding and its working principle is quite the same as the resistance welding. Spot welding or resistance spot welding is a type of electric resistance welding used to weld various sheet metal products through a process in which contacting metal surface points are joined by the heat obtained from resistance to electric current. The working principle of arc winding is in a welding process the heat can be generated with an electric arc strike among the workpiece as well as an electrode.

It is a thermo electric process in which heat is generated at the interface surfaces of welding plates due to electric resistance and a controlled low pressure is. This welding process could be manual fully or semi automated. Resistance spot welding operation is used for joining the plates of railway tracks fuel tanks domestic radiators etc. Usually spot welding as also other erw machines are automatic and work on the following weld cycle.

Working principle of electric arc welding. The only difference here is that projection or embossed joints are used for the welding purpose. Resistance welding resistance welding working principle. In this article we have studied about welding transformer working and application.

In the projection welding as per the name different projections are formed for effective welding. In the last session we had discussed gas welding process and arc welding process and whereas in today s session we will discuss on resistance spot welding along with its definition construction working principle applications defects advantages and disadvantages.
