Welding is a process of joining two elements that can be made of the same material, but it is not necessary. Sufficient energy must be applied to these two elements to cause the edges to melt and join. Sometimes this is enough and you don't need to add anything to get these elements combined, but in most cases you need to add the so-called binder that will help join elements.
