Assignee:

Lincoln Global, Inc. - City of Industry CA

International Classification:

B23K 9/173
B23K 35/02
B23K 9/24

Abstract:

The invention described herein generally pertains to an improved process in the field of welding using longer than recommended contact-to-work-distances coupled with effectively reduced shielding gas flow rates by adding between 0.25-10 parts of at least one porosity reducing agent to the electrode composition comprising a lime-fluoride based slag, selected from the group consisting of: (a) at least one metallic nitride former selected from the group consisting of Ti, Zr, Ca, Ba and Al, including metallic alloys thereof or alloys which incorporate at least one of the identified metals, and further wherein when no Al is present in the at least one metallic nitride former, a Li compound is substituted; or (b) at least one rare earth metal selected from the group consisting of La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu, Sc and Y, including combinations of (a) and (b).
