METHOD AND SYSTEM OF USING GAS FLOW TO CONTROL WELD PUDDLE IN OUT-OF-POSITION WELDING

摘要

A system and method for using gas flow to control a molten puddle in out-of-position applications is provided. The system includes a high intensity energy source configured to heat at lease one workpiece to create a molten puddle and a housing assembly configured to supply a gas over the molten puddle in order to minimize sagging of the molten puddle in the out-of-position applications. The system also includes a gas source that is configured to supply the gas. The gas source is operatively connected to the housing assembly. The pressure of the gas in the housing assembly is in a range of 15 psi to 35 psi. The method includes heating at least one workpiece to create a molten puddle and supplying a gas over the molten puddle via a housing assembly in order to minimize sagging of the molten puddle in the out-of-position applications.
