<p><P>PROBLEM TO BE SOLVED: To provide a composite welding method and a composite welding apparatus in which all of laser output, the feeding velocity of a first wire and the feeding velocity of a second wire are regulated so as to be proportional to welding velocity in the welding, by which the second wire is fed to a molten pool formed by a laser and an arc welding using the first wire. <P>SOLUTION: An arithmetic means 20 performs an arithmetic processing in such a manner that all of the laser output of a laser generating means 9, the feeding velocity of the first wire 3 controlled from an arc generating means 13 and the feeding velocity of the second wire 7 are made proportional to the welding velocity, thus satisfactory welding is performed, and further, the setting of welding parameters can be facilitated. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
