Abstract

PURPOSE:To produce a gas nozzle chip having a film which prevents sticking of a spatter by subjectng the surface of the gas nozzle or chip for an arc welding machine using inert gas or the like to a high frequency sputtering treatment. CONSTITUTION:A gas nozzle or chip 2 for an arc welding machine is preliminarily cleaned with trichloroethylene and is thereafter disposed on the table 7 of a base plate electrode 10. On the other hand, a ceramic plate 8 of a carbon plate or SiC, etc. is fixed as a target on a high frequency electrode 11 side. The inside of a chamber 9 contg. both electrodes 10, 11 is evacuated and a gaseous Ar atmosphere is maintained therein. The electrodes are connected to a high frequency power source to perform sputtering. A carbon film or ceramic film is thus formed on the surface of the gas nozzle or chip 2. The sticking of a spatter on the gas nozzle or chip is prevented if welding is performed by using such gas nozzle or chip and the generation of defective welding and the decrease in welding efficiency are prevented.
