Question:

Why should the electrode be baked before use?

Why should the electrode be baked before use?

Answer:

Ordinary carbon steel electrode can not be used, but other electrodes, especially white steel, must be baked, because the welding rod welding when there will be holes
I don't want to tell you anything that is very theoretical and very textbook. Our project is very wet in the south, so the steel production base often does.The main reason for baking the electrode is (or to prevent) the welding rod from being wetted.Welding rod after wetting, in the welding of workers will indirectly cause more slag, more bubbles, the current is not good control, burn the main tendons, and the strength of the steel bar connection will not meet the design requirements.That's all.
