Joining two or more pieces of metal together by melting or burning the search with an electric arc as a source of heat. The use of electricity as a source of light is divided into two:
1. Electric resistance welding
2. Electric arc welding flame
Electric resistance welding is a welding process will be undertaken by an electric current flows through the fields or the surface of the workpiece to be on the dial or the welding. Prisoners in the electric current will arise in the fields of touch and useful heat will cause the surface of the melt grafting. Thus, the pressure exerted between the two materials will cause a blend of work between the two pieces are connected. While electric arc welding is a welding flame that is done by changing the electrical current into heat to melt or melt the surface of the object to be spliced and generate electricity through the flame arc electrodes. The occurrence of an electric current is caused by the voltage difference between the two poles of the work and electrode. This voltage difference is called voltage arc flame.
This voltage large between 20 volt and 40 volt
b. Electrode
Electrodes is an important part in the electric arc welding. During the welding electrodes will expire at on welding. Will affect the types of welding electrodes, so that the selection and type of elektrode be appropriate. Based on the protective film can be divided into two kinds of electrodes and electrode webbed plain.
Webbed electrode consists of the core and the protective or flux. Coating flux coating done with the way in spray, dip or destrus. Her purpose in this flux to the electrode when burning will produce co2 gas welding in order to protect the liquid, an electrical arc of oxygen that can undergo oxidation so that the weld material will affect the nature of the mechanism of the weld metal.
So the membrane electrode has functions such as:

So the membrane electrode has functions such as:
- Prevent formation of nitric oxides and metal during the welding process takes place.
- Creating a protective shaft so as to reduce the speed of cooling, with the aim of the welded workpiece does not have brittle or fragile.
- Provide specific properties of the weld by adding certain substances contained in the membrane.
- Stabilize the arc and the arc flash drive so easy to control.
Hence the choice of electrode should be appropriate to consider the following.
• Type of weld metal to be in
• Thickness of material to be welded
• mechanical strength that is expected from the welding
• Outstanding welding and
• The seam of the workpiece
• Type of weld metal to be in
