Abstract

Per sostenere internamente la saldatura anulare durante l'operazione di saldatura di due estremità di tubo di due tubi allineati reciprocamente, viene usato un anello di supporto di saldatura costituito da pezzi di anello comprendenti almeno un corpo di supporto che delimita la circonferenza esterna dell'anello di supporto di saldatura.L'invenzione fornisce una forma costruttiva semplice dell'anello di supporto di saldatura.
