Izicelo:

I-AWS 5.20 E71T-GS iwucingo olubheke zonke izindawo, oluzivikelayo olwenzelwe i-single fillet kanye ne-lap welding ku-galvanized noma i-carbon steel njengo-gauge engu-20, ngaphandle kokushiswa. I-Gasless Wire E71T-GS ijwayele ukusetshenziselwa imishini yokushisela ye-volt eyi-110 ephathekayo, enikela ngesenzo se-arc esibushelelezi nge-spatter encane kakhulu. Ijubane lokuhamba liyashesha, ukungena kuhle futhi ukususwa kwe-slag kulula.

QAPHELA: Njengazo zonke izintambo ezivikelekile, i-E71T-GS inezinhlanganisela ze-fluoride, ezidinga ukunakekelwa okwengeziwe ekungeneni komoya lapho zisetshenziselwa ukushisela insimbi eshubile. I-zinc oxide eyakhiwe ngesikhathi sokushisela akufanele ifuthwe ngoba ingadala umkhuhlane wensimbi. Lapho ushisela ngaphakathi noma endaweni ebiyelwe, qiniseka ukuthi umoya omncane wanele.

Ukuzivikela, izintambo ezi-cored-cored wire zohlelo lokusebenza olulodwa lokudlula. Kuhle kakhulu ukusetshenziswa kumageji amancane wensimbi ehlanganisiwe nensimbi. Ijubane lokuhamba liphezulu futhi imiphetho ye-weld ibushelelezi. Inesenzo se-arc ebushelelezi, ukumbozwa okugcwele kwe-slag, ukususwa kwe-slag okulula nokusabalalisa okuphansi. Ayikho igesi yokuvikela edingekayo. Ukusetshenziswa kwe-DC straight welding welding yamanje kunciphisa ubungozi bokusha. Ukusebenza kahle kokusetha kuphakeme kunokwama-electrode ensimbi avikelwe.
