Red Seal Welding Practice Exam

An E71T-9MJ-H4 wire is an example of a dual shielding flux-cored arc welding wire. This type of wire is specifically designed for use with a shielding gas, such as carbon dioxide or a mixture of carbon dioxide and argon, in addition to the flux coating found inside the wire. This combination helps to reduce the amount of spatter and improve overall weld quality. The other options listed are not dual shielding wires, with E71T-11-H4 being a self-shielded wire, E6010 being an electrode for stick welding, and E308L being a solid MIG wire for stainless steel. While these other options may be useful in their own applications, they do not fall under the category of a dual shielding flux-cored arc welding wire.
