1. EQUIVALENT STANDARD AND CONFORMITY
2. CHARACTERISTICS AND APPLICATION
- The basic advantage of automatic and semi-automatic welding under the flux layer of EL12 welding wire is to ensure the quality of the weld, which has uniformity, high productivity, and the ability to save welding wire.
- The EL12 allows the use of high welding amperage, high heat source usefulness, and fully automated or fully automated operations that cause – maintain the arc – move the wire to the full length of the weld.
- EL12 is a welding wire with low carbon content, medium manganese and silicon content, and extremely small sulfur and phospho- rus impurities, creating welds with high strength and toughness.
- EL12 is built with high precision, even wire direction, and is plated with a layer of high purity copper for preservation and stable solder- ing.
