The invention is concerned with a welding flux composition comprising a first alloy including iron, at least two metals reactive with oxygen under welding conditions and selected from the group consisting of aluminum, titanium, zirconium and boron and a weld improving metal selected from the group consisting of magnesium and manganese, said first alloy comprising from about 1 percent to about 4.5 percent by weight of the flux composition. The invention is also concerned with a weld forming composition comprising a metal tube having therewithin a welding flux as set out above. The invention is further concerned with a process for reducing particulate matter produced during the welding operation, comprising a welding flux used in said operation including from about 1 percent to about 4.5 percent by weight of the above first alloy.
A welding flux composition which produces a reduced amount of particulate matter, comprising:
A process for reducing particulate matter produced during a welding operation, comprising including in a welding flux used in said operation from about 1 percent to about 4.5 weight percent based on the total weight of said flux of a first distinct alloy having at least four metals, said first alloy including iron, at least two metals reactive with oxygen under welding conditions selected from the group consisting of aluminum, titanium, zirconium and boron and a weld improving metal selected from the group consisting of magnesium and manganese.
A weld forming electrode comprising a metal tube having therewithin a compacted welding flux comprising:
