GB/T E5015-A1

AWS A5.5 E7015-A1                       

Description: R107 is a pearlitic heat-resistant steel electrode with a low-hydrogen sodium coating containing 0.5% Mo. Use DCEP (direct current electrode positive) and can welded in all positions.The weldment must be preheated to 90 ~ 110 ℃ before welding.

Application: It is used for welding boiler pipes with working temperature below 510°C (such as 15Mo, etc.), and can also be used for welding general low-alloy high-strength steel.

Chemical composition of weld metal(%):

Mechanical properties of weld metal:

Diffusion hydrogen content of deposited metal: ≤6.0mL/100g (glycerin method) 

X-ray inspection:  I grade

Recommended current:

Notice:

1. The electrode must be baked for 1 hour at 350℃ before welding operation;

2. It is essential to clean up rusty, oil scale, water, and impurities on welding parts before welding.
