Gents, This is for a technical clarification. Please advice. Sub: For SS-CS welding normally we are using 309. i.e. this weld metal will protect the parent SS & CS as a separation media, in order to avoid those 2 metals from direct contact. (Pease correct if I am wrong). As per my knowledge if SS & CS will become in direct contact means, there is a possibility of galvanic corrosion. So my doubt is whether this weld metal will act as protection media against that? (By using this 309, manufacture's mainly concentrating on its tensile strength type phenomena or giving more priority to take precaution against these type corrosion.) I would like to get metallurgical explanation Regards |
