Gas metal arc welding process.

摘要

The gas metal arc welding process of the present invention extends the axial spray metal transfer range with a non rotating arc from 10 to 25 Ibs/hr using an electrode wire diameter between .035 to .052 inches. The process is carried out by maintaining an electrode extension of between 3/4 to 1 1/4 inches with a three component shielding gas mixture consisting essentially of argon and oxygen in combination with carbon dioxide or carbon monoxide in a volume proportion of oxygen 1-2%, carbon dioxide 8-15%, balance argon. The arc voltage is maintained in a range of between 29 and 40 volts.
