Abstract:
This disclosure relates generally to arc welding. In an embodiment, a welding system has a welding gas supply system configured to supply a gas flow including a shielding gas and a fluorine-containing gas to a weld pool. Furthermore, the shielding gas is configured to control an atmosphere surrounding the weld pool, the fluorine-containing gas is configured to reduce diffusible hydrogen in the weld pool, and the fluorine-containing gas is substantially free of sulfur.
