2019年5月22日 · ER70S-3 is the most widely used GMAW wire. ER70S-4 wire and filler wire are suitable for the welding of steels whose conditions require that they provide more deoxidation capacity than ER70S-3 filler metal. Typical base metal standards are usually the same as ER70S-2. No impact test is required.

er70s-4（er50-4）类别的焊丝和填充丝适用于焊接其条件要求比 er70s-3（er50-4）填充金属能提供更多脱氧能力的钢种。典型的母材标准通常与 er70s-2（er50-2）类别适用的一样。

ER70S-4 is a silicon and manganese deoxidized wire used for mild and low alloy steel general purpose fabrication. A well balanced silicon and manganese content permits its use with CO2, Argon-Oxygen mixtures, or mixtures of the two.

Your first choice when welding on metals with a low to medium presence of surface contaminants such as rust or mill scale.

er70s-4 1.Si含量(0.65~0.85%)比ER70S-3稍高些，脫氧效果比 ER70S -3佳。 2.不要求衝擊性能，衝擊 值會 比ER70S-2 & ER70S-6 & ER70S-7 差。
