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 xem trực tiếp bóng đá việt nam hôm nay is to ensure the quality of the weld, which has uniformity, high productivity, and the ability to save welding xem trực tiếp bóng đá việt nam hôm nay.
- 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 xem trực tiếp bóng đá việt nam hôm nay to the full length of the weld.
- EL12 is a welding xem trực tiếp bóng đá việt nam hôm nay 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 xem trực tiếp bóng đá việt nam hôm nay direction, and is plated with a layer of high purity copper for preservation and stable solder- ing.
