The inclination of the electrode during the welding process affects the rate of heating of the metal. Therefore, the choice of the optimal angle depends on the types of welded joints and the types of welds used.
The next important nuance in welding is how the electrode moves in the process of creating a weld. The trajectory of movement is selected depending on the thickness of the workpieces and the types of welding joints.
The following schematic diagram clearly illustrates the allowable electrode paths when creating vertical, horizontal and overhead joints:
Transverse oscillatory movements of the electrode during welding provide good heating of the root of the weld and its edges, make the connection more durable. Also, the amplitude of the oscillation allows you to get a seam of a given size. There are various looped shapes that the electrode draws during welding – “ladder”, “triangle”, “tree”, “crescent”, “loop”. The choice depends on the types of welding connections, as indicated in the diagram above.
