This post was last edited by *eyu on 2015-9-14 09:56. For welding composite materials, which certified code should be used: SMAW-FeIV-1G-12-Fef4J or SMAW-FeII-1G-12-Fef4J? Additionally, for welding dissimilar steels such as Q345R and S30408, the previous notation was SMAW-II/IV-1G-12-F3J; it has now changed to SMAW-FeII/FeIV-1G-12-Fe3J. Or should SMAW-FeIV-1G-12-Fef4J be used directly?
Qualification for carbon steel used in the welding of composite plates + Qualification for stainless steel used in the welding of dissimilar steels
What does \"white steel\" refer to? Is it carbon steel?
“Is there a difference between SMAW-FeIV-1G-12-Fef4J and SMAW-FeIV-1G-12-Fef4J”? Was it written wrong?
White steel is a colloquial term. . . Haven’t you heard of it?
To be precise, none of your projects are correct. . Composite plate welding actually involves base layer welding and overlay welding, requiring a minimum of 2 distinct welding processes ； For example, manual welding at the grassroots level, flat welding ； It is SMAW-FeII-1G(K)-12-Fef3j; composite layer welding, flat welding ； It might be SMAW(N6)-FeII-1G-Fef4;
Many manufacturing plants in the north refer to stainless steel collectively as \"white steel,\" while carbon steel and low-alloy steel are collectively called \"carbon steel.\"
Composite plate welding refers to the welding qualifications for butt welding + surfacing welding; both qualifications for welding dissimilar steels should be listed
For the welding of composite plates, select the base metal welding procedure code plus the surfacing welding procedure code; for welding of dissimilar steels such as Q345R and S30408, SMAW-FeIV-1G-12-Fef4J is sufficient
