Results of electric welding example

determine the current strength used.
the current used in welding should be appropriate, as it will affect the welding result. in determining the strength of the current should pay attention to some important things, including:

 diametr electrode
 thick material welded
 type of electrode used
 position of welding
  polarity (properties) of polarization

The velocity of the hand pulling or pushing the electrode at weld time must be stable, so that it will obtain smooth and smooth welding rigid with good penetration if the electrode is moved quickly, hence the heating of the base material is less, so that the welding of small welds will be obtained by penetration shallow. if the electrode is moved too slowly, a wide and strong welding ridge will be obtained with a deep penetration. even sometimes causing damage to the welding side or often called under cut.
