What brand is the e4315 electrode?

[VanLeilani]

e4315 electrode is of the J427 brand. Introduction to E4315: The J427 brand belongs to the low-hydrogen sodium-type coating low-carbon structural steel electrode. It is an alkaline electrode, used for welding with DC reverse polarity (ground clamp connected to the negative pole -, welding torch connected to the positive pole +). It is used for important structural welding of low-carbon structural steels such as Q235 and Q245R. Introduction to electrodes: An electrode (covered electrode) is a metal strip that melts and fills the joint of a workpiece during gas welding or electric welding. The material of the electrode is usually the same as that of the workpiece. The electrode is a consumable electrode coated with flux for shielded metal arc welding, consisting of two parts: the flux coating and the core wire. According to the national standard "Steel Wire for Welding" (GB1300-77), welding-specific steel wires can be classified into three categories: carbon structural steel, alloy structural steel, and stainless steel.
