Abstract
Inventia se refera la un procedeu si la un amestec pentru îmbinarea, prin sudare aluminotermica a elementelor de cale ferata, de exemplu, a unei încrucisari, turnata din otel manganos si o sina de otel carbon. Procedeul consta din utilizarea unei sudari aluminotermice, la care topitura este austenitica, iar zona de îmbinare, dinspre capatul elementului din otel manganos, este supusa unei raciri mai intense fata de zona îmbinarii dinspre capatul elementului din otel carbon. Amestecul utilizat care formeaza topirura austenica are un continut de carbon mai mic de 0,2 % un echivalent de ncihel cuprins între 13 si 35 % si un echivalent de crom cuprins între 8 si 25 %.
