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.
Spot welding machine working principle.
The only difference here is that projection or embossed joints are used for the welding purpose.
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.
In the projection welding as per the name different projections are formed for effective welding.
Working principle of electric arc welding.
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.
Resistance welding resistance welding working principle.
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.
Introduction to spot welding working principle of projection welding introduction to spot welding spot welding is one of the type of welding processes.
This welding process could be manual fully or semi automated.
The working principle of resistance welding is the generation of heat because of electric resistance.
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 process uses two shaped copper alloy electrodes to concentrate welding current into a small spot and to simultaneously clamp the sheets.
Projection welding is one of the types of resistance welding and its working principle is quite the same as the resistance welding.
Usually spot welding as also other erw machines are automatic and work on the following weld cycle.
Whenever the current flows through electric resistance then heat will be generated the same working principle can be used within the electric coil.
