WELDING TECHNIQUE

Welding technique applied during the welding process can be done by following the general rules or provisions that apply to welding. The scheme shows that the welding process parameters for the welding done on the position under the hand include:

1.    Direction of welding

The direction in question is the direction of welding electrode movement at the time of starting the welding process. The direction of welding is very dependent on the welder and construction of welded joints.

2.    Movement electrodes used

Electrode movement a swing at the time of welding electrodes, where the swing of this electrode can be moved in a straight line, half circle, full circle, triangle, swaying figure of eight, and in four terms. These electrodes will be seen in the weld metal beads that formed.

3.    Angle between the electrodes with the work piece longitudinal direction angle of electrodes formed on the electrode moving direction makes an angle with a range of 70 º-80 º.

4.    Angle between the electrode with the work piece transverse direction angle between the electrode and the work piece in welding in this transverse direction forming an angle of 90º.

5.    Electrode to the work piece distance a good approach large electrode diameter is used.

6.    Distance/gap between the work piece which will be connected
wine is good between the work piece is the diameter of welding wire used. The reason for providing a gap or spacing is intended to produce a better weld penetration to reach the inner side of the weld metal.

7.    Welding speed

The speed of welding is a very important parameter in producing quality weld connections that meet the standards.

8.    Penetration welding

Penetration is the penetration depth of the weld metal reached on a metal base material on this welding. Penetration is also a melting between the electrodes with the basic material of the upper edge to penetrate the plate.
