Welding work using an electrode, the most common in everyday life and on industrial sites. Quality welding of metal structures depends on many variable factors. But, both a master and a novice specialist can achieve a good result.
Working with an electrode
In any work, not only theoretical knowledge is needed, but also practical experience. Choosing the right equipment is key to the end result, but don't forget how to properly handle the electrode so that the two surfaces to be welded are firmly held relative to each other:
- After the arc appears, you need to get used to the brightness of the emitted light.
- Optimal inclination of the electrode relative to the parts is 30-60 degrees;
- The direction of the electrode movement is practically irrelevant.
- The speed of movement depends on the thickness of the metal.
Important: if you first firmly fix the parts, make them motionless relative to each other, the quality of the seam will increase significantly. As the molten metal cools, it tends to attract two parts, bending their position relative to each other.
Typical beginner mistakes
As practice shows, most people, at the very beginning of their career as a welder, make the same mistakes. If you know them in advance, you can initially show a completely acceptable result. Avoid abrupt movement of the electrode by depositing a minimum amount of metal.
The slag that forms during the formation of the seam must be removed with a special hammer. Almost immediately, without waiting for the parts to cool down. But, not instantly, as soon as the welder has finished moving the electrode just a few centimeters.
