Abstract

본 발명의 버트용접조인트는, 2개의 파이프, 특히 상이한 파이프재료, 특히 페라이트/마텐자이트 및 오스테나이트 파이프재료로 만들어지고, 상이한 열팽창계수를 가지는 스팀제네레이터 파이프 사이의 버트용접조인트에 있어서, 파이프의 재료와 용접의 필러 사이의 열챙창계수에 큰 차이가 있을 때, 파이프단부에서 용접에의 트랜지션영역이 파이프 종축에 수직으로 형성된다.The butt welded joint of the present invention is a butt weld joint made of two pipes, in particular different pipe materials, especially ferrite / martensitic and austenitic pipe materials, and having different thermal expansion coefficients, When there is a large difference in the thermal solute coefficient between the material and the filler of the weld, a transition region from the pipe end to the weld is formed perpendicular to the pipe longitudinal axis.
