The only difference here is that projection or embossed joints are used for the welding purpose.
Spot welding machine working principle.
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.
Usually spot welding as also other erw machines are automatic and work on the following weld cycle.
Today we will learn about resistance welding principle types application advantages and disadvantages.
This is glowing electrical discharge among two electrodes throughout ionized gas.
The working principle of resistance welding is the generation of heat because of electric resistance.
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.
Introduction to spot welding working principle of projection welding introduction to spot welding spot welding is one of the type of welding processes.
The resistance welding such as seam spot protection works on the same principle.
Resistance welding is a liquid state welding process in which the metal to metal joint created in liquid or molten state.
Resistance welding resistance welding working principle.
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.
Whenever the current flows through electric resistance then heat will be generated the same working principle can be used within the electric coil.
This welding process could be manual fully or semi automated.
The process uses two shaped copper alloy electrodes to concentrate welding current into a small spot and to simultaneously clamp the sheets.
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.
Projection welding is one of the types of resistance welding and its working principle is quite the same as the resistance welding.
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.
