<p>An electrode wire for welding has at least one longitudinal cavity (3) provided in its metallic base (1) and filled with a charge (2). The cavity (3) has a slot-like cross-section, the ratio between its width and surface being within 0.005 to 0.5, whereas the ratio between the cross-sectional surface of the cavity (3) and that of the wire is within 0.05 to 0.5.</p> |
