Can cast aluminum actually be welded? Cast aluminum welding
There are many things where cast aluminum is used, but can it also be welded and repaired?
Yes, cast aluminum can usually be welded, in the end it always depends on the composition. Whether other alloys such as magnesium or similar are contained here.
We specialized in aluminium repair welding nine years ago. Among other things, of course, aluminum casting and have been able to gain a lot of experience here and have already been able to implement a lot.
There are a few things to consider with aluminum casting, but the most important point is cleanliness, the right welding filler material and of course the right welding machine settings.
Or save time and money and achieve results quickly and easily.
If you stick to these things, you can really do a lot of repairs, weld cracks and also carry out build-up welding, for example, if you then want to mill material off again.
If you want to weld cast aluminum yourself, this is of course also possible.
Here are a few tips:
The most important thing is the preparation, i.e. cleaning the welded part. First of all, the coarse dirt must be removed and it is best to clean the whole part immediately so that you do not have any smoke development in your workshop.
Then mill out the area to be welded, e.g. the crack, so that you have something to fill it with and the area is also really clean.
Then clean again with acetone and wipe off.
Now you can weld but which welding wire??? Unfortunately there is no formula here, I can only tell you how I do it and that is with an Almg5 wire and then I just test what works best and you can see that really quickly.
