Product Description

[CS Welding Electrodes]J507 GB E5015 AWS A5.1 E7015 Low-Hydrogen Sodium Coated Cs Electrode 2.5mm 3.2mm 4.0mm 2.5mm 5.0


E7015 2.0/2.5/3.2/4.0/5.0 mm Carbon Steel Electrodes


Specification:AWS A5.1 E7015 is low-hydrogen sodium coated carbon steel electrode. It must be operated on DCEP. It has very good welding usability that enables it to perform all-position welding, has stable arc, removal of slag is easy and has low spatter. The deposited metal has good mechanical performance and crack-resistance, which offers good low temperature toughness.


Conform to Standard

GB/T 5117 E5015

AWS A5.1 E7015

ISO 2560-B-E 49 15 A


Purpose:It's widely used for welding key medium-carbon steel and low-alloy steel structures (under pressure and moving loads), such as 16Mn, 09Mn2Si, 09Mn2V and A, B, D and E steel for ships, etc., and also used for welding on thick plates and hard-to-weld carbon steel structures.

1. The electrode must be preheated at the temperature of 350°C for 1 hour. Preheat the rod whenever it is used.

2. The impurities such as rust, oil stains and moisture must be cleared off of the work piece.

3. Short arc is required to perform welding. Narrow weld path is preferred.
