Abstract

Inventia se refera la un dispozitiv pentru amplasarea corecta a materialului de îmbinare la sudura conduvtelor, prin autopozitionarea orizontala si radiala, dispozitiv care se adapteaza la suprafata interioara a unor conducte de diametre diferite si asigura retinerea materialului de sudura pe locul de contact. Dispozitivul, conform inventiei, la începutul operatiilor de sudura automata cap la cap a conductelor, prin actiunea a doua subansambluri circumferentiale, prevazute cu pistoane radiale, apartinînd unui conector interior, dispozitivul avînd niste tampoane independente din cupru, dispuse suf forma unui inel de tampoane independente din cupru, dispuse sub forma unui inel de tampoane, fixate individual pe niste elemente de sustinere a tampoanelor, sprijinite elastic de unul din subansamblurile circumferentiale cu pistoane radiale ale conectorului interior, în scopul utilizarii la un domeniu larg de circumferinte ale conductelor ce urmeaza a fi sudate, fara decalalaje si distantari între tampoanele independente, care sa conduca la crearea de cavitati ce dau nastere la defecte de sudura, asigurînd o suprafata utila de suport a materialului de îmbinare, neteda, continua si de dimensiuni relativ mari...
