Welding can be really easy if you go for welding types that do not require an immense amount of knowledge to any extent. Flat welding is an example of a welding practice that requires a really minimal amount of experience since all you really need to do is slightly melt the end of a metal stick and then fuse it to a flat surface by holding it with a significant amount of pressure that would prevent it from moving around all that much.
However, if you were to look into horizontal stick welding, it is important to note that this requires a fair bit more expertise at the end of the day. If you want to weld something of this sort, you need to know how to create a t-weld. This is basically a weld that takes one stick and fuses it into the center of another. You are dealing with metal rods here rather than flat surfaces and they are almost always harder to work with due to their tendency to become unstable if too much heat is applied.
Keeping the top of the rod flexible enough can be tricky, but with enough practice you would be able to do it. The prep work that is involved in this process often takes a lot of time since you need to keep applying heat until the metal is at just the right kind of consistency. Patience is a virtue in the welding field, and that is perhaps most evident in situations where t-welds and horizontal welding might be required of you. Suffice it to say that this is a skill that takes years to develop.
