High speed carbon dioxide gas welding method |
摘要 |
An arc welding method which suppresses sputtering and which makes it possible to obtain a smooth bead penetration surface shape as in MIG or MAG welding, without producing undercuts or bumping beads. A carbon dioxide gas welding method effecting welding at welding rates of about not less than 1.5 m/minute using a consumable electrode and a welding power source having a control means for opening a short circuit at a rate of at least about 500 A/msec on detection of such short circuit, wherein welding is effected with a proper volume of globules under the welding conditions obtained by computing a welding voltage corresponding to the proper volume of globules by a first formula representing the relationship between the welding wire feed rate, the welding voltage and the volume of globules traveling to a pond of weld as the welding wire is melting and a second formula representing the relationship between the wire feed rate, the welding voltage, and the period of globules traveling to a pond of weld as the welding wire is melting.
