SPOT AND PROJECTION BENCH WELDING MACHINES 2101D..2144D-2102N

Electrical resistance welding is a process of joining metals using heat generated by the electrical resistance of the material itself. The parts to be joined are placed in contact with each other and passed through by an electric current. The passage of current generates heat that melts the metal in the contact zone, thus creating a permanent joint.

Electrical resistance welding offers several advantages over other welding methods, including:

• High joint strength and reliability

• High production speed

• Low heat input

• Clean and slag-free process

• Possibility of welding different metals

   

Electric resistance welding is used in a wide range of industrial applications, including:

• Auto Body

• Household appliances

• Metal construction

• Railway industry

• Electronics manufacturing
