<p>The process for metal active gas welding of two metal e.g. steel pieces with a rotary electric arc and a solid fuse wire that supplies a protection gas, comprises assembling two metal pieces one after the other to define a circular 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.

The rotation of the electric arc is obtained by implementing a current intensity of less than 360 A and/or voltage of less than 35 V. The metal pieces have a thickness of 1-3 mm.</p> |
