Product Overview

Description

THJ507                                                     AWS A5.1 E7015

Basic-sodium Type Electrode                              ISO 2560-A-E42 3 B 22 H5

GB/T 5117 E5015

 

Applications:

It is suitable for the welding of carbon steel and low alloy steel structure, such as Gr.50 etc.

 

Characteristics: 

THJ507 is basic-sodium type electrode with low hydrogen. Can be weld for all-position with DC⁺ only. It have excellent welding performance as good arc stiffness, little spatter, easy slag removal etc., and perfect mechanical properties of deposited metal.

 

Welding Positions:

PA, PB, PC, PD, PE, PF

 

Attention:

1. The electrode must be re-dry by 350℃-380℃ for 1 hour before welding.

2. The rust, oil, water and other impurities of the weld area must be removed before welding.
