Description: Low-alloy steel electrode refers to low-alloy high strength steel electrode whose tensile strength is over 500MPa and which is used for structural welding. When selecting welding electrodes, one should do according to the requirements of their chemical composition, mechanical properties, crack-resistance performance and, at the same time, consider comprehensively all kinds of factors like shapes of welded structures, working conditions, stress status and so on. If necessary, do some welding experiments and take some technical measures so as to guarantee welding quality.
