All welcome. We continue our welding stories, these stories are endless, but now analyze an important topic, and how to maintain the electrode during welding? Let's start from afar, what welding and weld? Can a long and tedious to write clever words, as written in the welding textbooks, but I will not do, because it is boring and not interesting, let's be explained by common human conversational tongue! Go! Guys remember, welder - is the operator and the master of the welding arc. And what is the arc? This stream of molten metal which flows into the weld pool under pressure and cooling down instantly forms a so-called weld. I must say that I write my articles mainly for beginners in welding - welders experienced steep it will be interesting, so that an experienced welder close this page. Simplicity - this is the highest level of difficulty! We simpler - represent a stream of water which flows on the very cold surface and freezes instantly, it will be the formation of the weld.
Our job as a welder to make so that this jet freeze tightly and evenly. The electrode will perform our role hose with water simplified fantastic stories that getting on a cold surface would quickly freeze. Our task is correctly to the hose (electrode) to get the right seam. Here the trick is what? Yes, all depends on the thickness of the weld metal. Pattern will be here like this - the thicker the base metal, the more movements you need to make an electrode, and the more you need to put the welding current on your welding machine. Take a thin weld metal - from 1 to 3 mm, here a jet of sufficiently our electrode lead directly and without hesitation. Begin to cook thicker metal, and even if not in the joint, and corner joint, there is already an electrode need to wave! Well, that is oscillate. Let us show you a picture of these movements.
To be honest, especially not to drive on the recommendations of the electrode movement, no I would not say that the movement does not need to do - of course necessary, but just experiment with such options vibrations and pick for yourself the most comfortable to operate - still with all these properly made joint movement was the same, believe me not experimented time. There is quite a big role is played by the current strength - also need to experiment on a piece of iron left before welding the main structure, the main piece of iron. I tried to CHERMET amperage, if everything is fine - do not be afraid to boil. Let's summarize our today's topic - how to the electrode during welding. Metal thin - up to 3 mm - preferably lead directly picking up the normal force of the current, which would not give a shit, and not burn the metal, but here it is necessary to experiment on a scrap ferrous metal, yet if special welding experience. But if the metal thick - more than 3 mm, the wave electrode here, and which use the motion - experiment itself on ferrous metal. Hopefully less razyasnil this at the beginning of the difficult subject of welding. Guys, let's look vidos is formed weld, will be especially interesting for beginners, and I myself really like this video channel cutting Welding electrodes.
