Product Description

Best Price Low Alloy Steel Electrode AWS E9015-G Permanent Welding Electrodes

 Low alloy steel electrode is  low hydrogen iron powder type,low alloy welding rod, For Welding of Low Alloy  Steels Structure of Same Grade.
       Our products are included  AWS E7015-C2L(2),  E9015-G, E8015-G, E9016-C1(3), E9016-D1, E10015-D2, E10015-G, E10015-G(2),  E12015-G, E12015-G(2).
Application
      Low alloy steel welding  electrode AWS E8015-G mainly used in welding of low  alloy steel with corresponding grade of strength. Low alloy steel electrode  also applied in welding of 3.5%Ni low alloy steel structures for working  temperature of which is -100ºC and welding of low alloy steel with  corresponding grade of strength.Instruction 
      1. The oil stains and rust on the welding should be cleared away. 
      2. Pls use stainless steel brush cleaning bead  to avoid iron mied  affacting weld quality. 
      3. Pls Dry 60 minutes at 300-350℃  before welding.  
      4. Take out a small quantity into 100-150℃ drying cylinder, when operation.  
      5. Do not carry electrode over half-day using quantities. 
      6.When swing the electrode, swing width should be within 2.5 times of  the electrode diameter. 
      7. Try to keep short arc and low current, in order to reduce creazing  and improve toughness.

1. Pressure vessels and pipelines
Applicable scenarios: LNG storage tanks, petrochemical reactors, high-pressure pipelines (such as X70/X80 pipeline steel).
Core advantages:

• Yield strength ≥550 MPa, meeting the structural strength requirements under high-pressure conditions.
• -46℃ low-temperature impact toughness ≥27 J, adapting to deep cold environments such as liquefied natural gas (-162℃) storage and transportation.
• Low-hydrogen coating inhibits hydrogen-induced cracking to ensure long-term safe operation of pressure-bearing equipment

2. Power station equipment

• Applicable scenarios: power station boiler steel frame, turbine load-bearing beam, high-pressure valve connection.
• Key performance: stable high temperature creep resistance, welds are not prone to fatigue cracking under long-term alternating loads.

1.Large bridge construction
Applicable scenarios: steel box girders of cross-sea bridges, high-speed rail steel bridges, and urban viaducts.
Core value:

• Tensile strength ≥ 620 MPa, to cope with the combined effects of vehicle dynamic load and wind load.
• Elongation 18%~20%, to improve the seismic performance of the structure (such as bridges in earthquake-prone areas).
• All-position welding adaptability, convenient for on-site high-altitude operations and complex node welding.

2.Rail transit vehicles
Applicable scenarios: high-speed rail carriage frames, heavy truck frames, crane booms.
Advantages: Good weld plasticity, tolerance to frequent vibration and impact, and reduced risk of fatigue fracture.

1. Shipbuilding
Applicable scenarios: merchant ship keel, marine engineering ship deck, pressure vessel cabin.
Performance matching:

• Excellent corrosion fatigue resistance, adaptable to high salt spray and high humidity marine environment.
• Low hydrogen process avoids stress corrosion cracking of welds under seawater corrosion.

2. Offshore platform
Applicable scenarios: oil drilling platform steel structure, cross-sea wind power tower connection.
Key requirements met: high strength to resist extreme loads such as typhoons and waves, low temperature toughness to ensure normal operation of equipment in cold waters such as the Arctic Circle.

1. Engineering machinery manufacturing
Applicable scenarios: excavator boom, crane steel structure, mining machinery frame.
Core performance:

• High-strength support equipment heavy-duty operation (such as mining excavator bucket connection).
• Excellent crack resistance, reducing weld cracking problems caused by frequent start and stop.

2. Metallurgical equipment
Applicable scenarios: steel mill rolling mill frame, blast furnace steel structure, heat treatment furnace bracket.
Advantages: resistant to high temperature oxidation and thermal fatigue, suitable for high temperature and high dust environment in the metallurgical industry.

1.High-strength structural repair
Applicable scenarios: reinforcement of old bridges, crack repair of heavy equipment, welding of aerospace fixtures.
Process advantages: low-stress welding of old structures can be achieved through short-arc narrow weld technology, reducing the thermal impact on the original components.
2.Construction in low-temperature environments
Applicable scenarios: Arctic pipeline construction, steel structure workshops in cold regions, and cold storage equipment welding.
Key performance: -46℃ impact toughness meets the standard to avoid brittle fracture of welds at low temperatures.
