The process for metal active gas welding of two metal e.g. steel pieces with an electric arc and a fuse wire that supplies a protection gas, comprises assembling two metal pieces one after the other to define a weld joint, simultaneously operating fusion of the metals with the electric arc along the weld joint and progressive fusion of the fuse wire, depositing a molten metal at the surface of the joint to obtain a welding cordon after cooling, and protecting the weld joint using the protection gas. One of the metal pieces is a first cylindrical bottom.

One of the metal pieces is a first cylindrical bottom, and other is a second cylindrical bottom connected to the first bottom in an edge to edge configuration. The fuse wire is a solid wire having a diameter of 1 mm. The metal pieces have a thickness of 0.5-5 mm. |
