Cast steel cylinder welding with electrode

Hey sweat fan greetings,

How best to weld cast steel cylinders with electrodes?

When welding cast steel cylinders, there are of course a few things to consider. The first thing to consider is what needs to be welded. If, for example, a cooling fin is cracked or broken off and needs to be welded back on, it is always advisable to grind down the top layer of metal first. So that it is really bright, the electrode ignites better and the fleece behavior of the electrode is also much better.

What is the best electrode to use for welding? I recommend a pure nickel electrode for this. This is best used for this, or is best suited for it. Then it is also very important that you only weld piece by piece and do not weld through everything at once.

Why should you do it this way? It is important here that not too much heat is applied, because that is precisely the problem, which then leads to cracks in the material. Which is of course extremely bad. It is therefore best to weld only about one to two centimeters and let it cool down. If you do it this way, you will also notice that you can touch the cylinder again relatively quickly, which should also ensure that really little heat is introduced.

Of course, this takes a little more time, but it works really well. We now even have a temperature gauge to make sure that we really try to stay between 60 and 80° so that the cylinder doesn’t get any warmer. And then you will really notice that there are no more cracks in the material.

If you need such electrodes, you are of course welcome to contact me, because unfortunately you usually have to buy a whole package and we can also sell them to you individually. Of course, they are not very cheap either, it has to be said.

We have also made a YouTube video about it, where you can see all the things in detail and where we explain the whole thing in more detail. Just take a look at it.

I hope I was able to help you with this article. I would be delighted to receive your feedback. And if you would like to find out and see more about welding, then take a look at our channels. It’s all about welding every day, e.g. Instagram and YouTube
