In order to produce the best welds, a lot of practice is required. It is a process in which trial and error become an essential part, so there is nothing to worry about if everything does not work out as planned in the beginning. However, you can keep in mind a few tips that will help you make the mistakes smaller to get the result you are looking for in much less time.
First of all you will have to get the right electrode for the job you are looking for, and the size of this should depend on the situation that is worked within the weld , taking into account gravity as an essential factor that affects the final result of a welding
You will need to have a good welding rack so that you have a good guide, especially if you are carrying out a vertical welding .
It is really important that as far as possible you seek not to undermine, which can happen since the electrode must be woven, and this work may be torn off at times and not enough metal fill is available. Remember also that having a larger puddle size will help you have a much greater control of the situation in general.
You should also try to stay away or away from strange sizes for metal, since most metals come in specific and common sizes.
Finally, make sure at all times that you know the arc length, that is, the distance of both the metal and the thickness of the electrode that you are using.
Follow these tips, practice a lot, and you will see that you will be able to develop a remarkably more uniform welding so that you can keep all your projects under control and the result obtained is not another but the desired one.
