China wholesale High Carbon Steels Seal Data Suppliers - High Carbon steels E7016 Manual electrode welding accessories – Honest Metal

Application&Standard&Note：

1. Suitable FOR WELDING OF CARBON STEEL AND LOW ALLOY STEEL, AS WELL AS THE CORRESPONDING STRENGTH OF BOILER, pipeline, vehicle, BUILDING, BRIDGE AND other STRUCTURES, SUCH AS Q345.
2. The standard we met: GB/T5117 E5016, AWS A5.1 E7016 & A5.1M E4916, ISO2560-A:E 42 3 B 1 2, ISO 2560-B: E4916 A

Welding precautions:
Before welding, the weldment must be entirely free of oil, rust, moisture, etc.; drying at 350°C for an hour; and drying with use
3. Use narrow pass welding and short arc welding; AC and DC reverse connections.

Can be used for welding low carbon steel and 490MPa high strength steel pipe butt joint, can realize single-side welding double-side forming.

The electrode belongs to the low hydrogen type, welding pipe and the general structure of the root of the weld, can realize single-sided welding two-sided forming, so it can save the cleaning welding heel, so that the welding efficiency can be improved.

Key points of process:

1, drying before use, 300~350℃ drying 30~60 minutes;

2, choose the appropriate current and groove, in order to get a beautiful back weld;

3. When extinguishing the arc, lead the arc pit to the side of the groove and then break the arc;

4. Arc starting time using arc starting plate or on the side of the groove arc;

5. Keep short arc welding;

6. Use AC or DC reverse connection.

Features

1. Low hydrogen potassium electrode, stable arc, beautiful forming, exquisite, little splash, easy de-slagging, good skin fire resistance, good porosity resistance.
2. table mechanical properties, good plasticity, impact toughness and crack resistance.

The national standard model for welding medium carbon steel and significant low alloy steel is E5016, while AWS model E7016 is the J506 low hydrogen potassium carbon steel electrode.
