Hydrogen Trapping Using Yttrium to Manage Hydrogen in HSLA Steel Welds

고장력강의 용접부에서 Yttrium을 이용한 수소의 트랩에 관한 연구

Yttrium has been investigated as hydrogen trapping site in pure iron and HSLA steel welds. Assessment of hydrogen trapping parameters for yttrium oxide has also shown the high potential of yttrium addition to improve hydrogen management in high strength steel welding. The purpose of this study was to reduce and control the diffusible hydrogen content in the weld deposit.
