Low Alloy Steel Electroderod of low-alloy steel class, high-tech production has many grades, of course, also have different types, characteristics and uses of various grades of low-alloy steel electrodes. Melt filled in the workpiece at the junction of the metal strips in the welding electrode (covered electrode) or welding. The material of the wire is usually the same as the material of the workpiece.

Low alloy steel electrodes, electrode (coveredelectrode) metal core welding coatings (drug leather) uniform pressure to the carefully painted on welding core. Core welding electrode metal core, in order to ensure the quality and performance of the weld, butt core content of metal elements, there are stringent regulations, especially the content of harmful impurities (such as sulfur, phosphorus, etc.), should be strictly limit, is superior to the base material.

High alloy steel, aluminum, copper, cast iron and other metal materials, welding core components in addition to the requirements of the weld metal similar, the same should control the content of impurities, and press process requirements often by adding certain alloying elements.

Electrode that is coated with a drug skin for SMAW melting electrodes used, it is composed by the drug skin and core welding two parts. In the electrode front medicine skin has a chamfer of about 45 °, which is in order to facilitate arc starting. In the tail section of bare core wire, welding rod total length about 1/16 to facilitate the welding forceps and is conducive to the conductive. The diameter of the wire Chung actually refers to the diameter of the core wire) 2,2 5,3. 2 or 3, 4, 5 or 6mm several specifications used small 3.2, small, small 5 III species, its length "L" is generally between 250 ^ -450 mm.
