Abstract

resumo patente de invenção: "método de reaquecimento de zona de solda de trilho". a presente invenção refere-se à obtenção de uma junta de soldagem que tenha resistência à fadiga superior que possa suprimir fendas por fadiga na direção horizontal na parte da coluna e fendas por fadiga de curvatura começando da parte de suporte em partes de soldagem do trilho. em um método de reaquecimento para partes de solda do trilho depois da soldagem do trilho, a distância (c) entre a área de reaquecimento (p) para a parte da coluna do trilho (2) e o centro da solda (q) é definida para 0,2 - 3 vezes o comprimento (lh) da haz da parte de solda. o comprimento (b) da área de reaquecimento (p) pode ser 0,5 - 5 vezes o comprimento (lh) da haz da parte de solda. a altura (a) da área de reaquecimento (p) pode ser 0,2 ou mais vezes a altura da parte da coluna do trilho (2). a temperatura (th) atingida no reaquecimento no centro da área de reaquecimento (p) pode ser 400 - 750°c e, além do mais, em relação à temperatura inicial (tw) (°c) da parte de solda durante o reaquecimento, pode satisfazer 0,375tw + 350 = th = 0,5tw = 600. 19792812v1
