How to make the weld bead even and beautiful

Every metalworker ever has to resort to electric welding. This work is not easy, it requires skill and knowledge of some secrets, but whoever does not learn anything does not know how. We will reveal one of these secrets, which makes it possible in practice to make the welding seam even and beautiful.
Beautiful weld

In order not to complicate the description of the process, we simply consider the formation of a weld bead on the surface of a sheet of metal 2 mm thick. If you learn to work with metal of such thickness, then welding of a thicker one will not cause any difficulties.
Metal sheet

We will cook, for example, with the marking electrode ANO 21,
electrodes

the current strength on the welding machine is set to 100A.

To begin with, with a chalk or a thick white marker, dots mark the line of the future weld on the metal. The line should be exactly white, otherwise it will not be visible through dark goggles or the glass of the shield.
marking line

The welding seam is driven by moving the electrode along this line sequentially from point to point and not holding it for a long time in one place, so as not to burn metal. However, the main thing with electric welding is not to rush and try to maintain the distance between the metal and the electric arc unchanged.

During hasty work, the welding seam is scaly, uneven and, after it is cleaned of scale,
descaling

looks like this:

With the right welding speed, the seam turns out to be smooth, even and neat, and noticeably differs from the hastily made seam. After cooling and descaling, it looks like this (on the left in the photo):

It is in the optimal speed of the electrode along the marking, not too fast and not very slow, that the secret to the formation of an even and beautiful welding seam lies. In practice, achieving such an electrode speed is not difficult at all, you just need to practice. This is done as follows.

If we arbitrarily mark the points on the seam marking line in the form of small circles, it turns out that during hasty work, the welder moves the point electrode to the point, starting from the edge of the previous one.
hasty seam

For optimal electrode driving speed, it is recommended that each subsequent point of the weld start not from the edge, but, as it were, from the center of the previous one. But, of course, without holding it in one place for a long time, so as not to overheat the metal and make a hole in it. This is the trick of forming a reliable and externally aesthetic welded joint.
proper welding

As a result, the seam turns out to be even and smooth, and the connection itself is of high quality. Of course, in order to learn how to make such welds, training is necessary, but it’s better to pre-train and “get your hand” on some “waste” piece of metal than to hurry up and hastily ruin the appearance of the desired product.

Please forgive me, I'm not a welder. But you have to cook sometimes. In my opinion this article is nonsense. All comes with experience. "Guest Vladimir" correctly said.

Well and so it is clear! Buy welding, buy 3 (three) packs of electrodes and start cooking !!! Perhaps by the end of the third pack something will start to turn out!
I saw welders on a railway check. Samples (strips) of blanks are given, they need to be overlapped ... And then in the laboratory the samples are checked for breaking. So different welders had different results! There is responsible work on the railway where a qualified (discharge, etc. tolerance) welder is required.
That's how simple it is. And for 3 years I wiped my pants in a bursa for a 4-bit electric welder
Did I understand correctly? Does ANO-21 of any diameter need a current of 100 A? ))))

In general, the question from the name
How to make the weld bead even and beautiful
For example, I didn’t get an answer ... They explained, not "how", but "What needs to be done for this" ... So everyone who cooks, and so they know, what are the requirements for the arc and welds .. . The question is different: "HOW to fulfill these conditions ???
Wrote "non-welder" ...))))
Even, I would say, "nizrazonesvarschik"))))
