Description
Properties and Applications |
SPEZIAL is a basic, double-coated multi-purpose MMA electrode. The composition of the double coating confers exceptionally good welding characteristics and a highly stable and directional arc. Very good gap bridging and ideally suited for root passes and positional welding. The glassy slag is easily removed from the finely-rippled weld seams, the excellent welding characteristics and ISO-V toughness to -30°C. |
What is double coating |
A double-coated electrode consists of two separate layers: The “outer layer” with higher basicity The “inner layer” rutil-acid The arc-stabilizing minerals and metal powders are concentrated in the inner coating, and the minerals delivering the gas shielding are concentrated in the outer coating. This combination enables unique weldability characteristics. During manufacturing the two coatings are pressed simultaneously in a single extrusion operation. Both coatings from different chemical compositions but very complementary, will give a better technical result |
