High Carbon steels SAW uaea uʻamea F7A2-EM12K ma faʻafesoʻotaʻi uʻamea flux
Faʻaaogaina mo le -30C aʻafiaga manaʻomia siosiomaga, fau vaa, fausaga uʻamea, masini mamafa ma isi meafaigaluega uelo.
O a uiga fa'apitoa?
●Uaea u'u arc fa'afefete mo le 480MPa vasega maualuga malosi; Faatasi ai ma le GXL-301 flux uelo, uelo arc combustion e mautu, faigofie ona aveese slag, aulelei pasi pasi faia.
●O le u'amea u'amea o lo'o i ai mea fa'ainisinia lelei ma maualuga le pasi o le X-ray.
