I second that, normally one would make a part on a big slab of steel. Afterwards the part needs to be removed by wire-edm and annealing (before/after i don’t know). Welding is a profession and just welding at locations like 3D printing has too many pitfalls IMO. The link above is from a duch designer, and although it is a nice testing if something like this works I don’t think that welding is something you’d get to make tolerances, just because of the stresses, warp etc. Haven’t seen a industrial 3D metal printer who works with welding.
