In this study, the diffusible hydrogen contents of each weld using three flux cored wires with different hoop types were measured. The hoop shape of the flux cored wire used in the experiment is one seamless type and two fold types. In general, the flux cored wire is manufactured in a spool type. When the spool type wire is exposed to air, the diffusible hydrogen content may vary depending on each winding position. Therefore, diffusion hydrogen contents according to the winding position of each flux core wire were compared. Second, diffusible hydrogen contents of spool-type flux cored wire were measured according to the change in time exposed to air. The test specimen was prepared in accordance with AWS A4.3 specification, and diffusible hydrogen contents were measured using the gas chromatogram method. The welding conditions were fixed at current 260 A, voltage 28.0 V, welding speed 45 cm/min, shielding gas 100% CO₂, and gas flow rate 25 ℓ/min. As a result, diffusible hydrogen contents tend to decrease as the wire located inside than the outside. The seamless-type flux-cored wire showed the least change diffusible hydrogen contents in the weld according to winding positions. Diffusible hydrogen contents of the weld using the fold-type flux-cored wire are higher than that of the seamless-type flux-cored wire weld. Diffusible hydrogen contents in the weld was different depending on hoop joint shapes of the fold-type flux-cored wire.
