Product Description

Product Description

Product Introduction of Gas Shielded Solid Welding Wire ER70S - 6

I. Basic Information

Product Name: Gas Shielded Solid Welding Wire ER70S - 6
Standard Compliance: Complies with GB/T 8110 - 2020 (G49A3C1S6 equivalent) and AWS A5.18 specifications.

II. Applications

This welding wire is designed for welding of carbon steel and low - alloy steel structures with corresponding strength levels. It finds extensive applications in industries such as engineering machinery manufacturing, shipbuilding, vehicle production, and petrochemical engineering.

III. Characteristics

Strength Grade: ER70S - 6 welding wire belongs to the 500MPa - grade carbon steel welding wire. When used with CO2 gas shielded welding, it exhibits excellent performance.
Welding Performance
Spatter: Generates minimal welding spatter during the welding process, ensuring a clean working environment and reducing post - welding cleaning work.
Forming: Produces aesthetically pleasing weld formations, which is crucial for applications where weld appearance matters, such as in some visible structural welds.
Deposition Efficiency: Features high deposition efficiency, allowing for faster welding and improved productivity.
Porosity Sensitivity: Has low sensitivity to weld metal porosity, reducing the risk of porosity defects in the weld.
Welding Positions: Offers good all - position welding processability, enabling welders to perform welding in various positions like flat, vertical, horizontal, and overhead welding with ease.

VI. Precautions
Pre - welding Cleaning: Before welding, it is essential to remove impurities such as rust, oil, and moisture from the workpieces. These impurities can adversely affect the welding quality, leading to defects like porosity and poor fusion.
Heat Input: The heat input during welding directly influences the mechanical properties of the weld. For more critical structures, it is recommended to use a lower heat input to ensure the best mechanical properties of the weld. The selection of heat input should be determined based on the importance of the structure; the more important the structure, the smaller the heat input should be preferably.
