WELDING ROD Thj506fe AWS A5.1 E7018 ELECTRODE

Product Overview

Description

THJ506Fe (E7018)                                           AWS A5.1 E7018

Basic Iron Powder Type Electrode                               ISO 2560-B-E4918 A

GB/T 5117 E5018

 

Applications:

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

 

Characteristics: 

THJ506Fe is basic potassium-iron powder type electrode with low hydrogen. Both AC & DC can be used and can be weld for all-position. It have excellent welding performance as good arc stiffness, little spatter, easy slag removal etc., and higher deposition efficiency.

 

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.
