I-HFW steel pipe amaphutha ekukhiqizeni

Imvamisa ephezuluipayipi lensimbi elishiselwe uma ukulawula umkhiqizo kungcono, i-fusion surface yensimbi encibilikisiwe noma i-oxide izosala.Uma ukusikwa kwesampula ye-weld kupholishwa, kuhujwa, futhi kuqashelwe ngaphansi kwesibonakhulu esibonakalayo, indawo ethinteke ukushisa imise okwesigubhu, ngenxa yokuthi unqenqema lomucu lungena ku-high-frequency current kusukela ekugcineni komugqa wensimbi futhi izingxenye zonqenqema eziseceleni ezinokushisa okukhiqizayo.Indawo ethinteke ukushisa iba mnyama kancane kunesisekelo sensimbi, ngenxa yokuthi ukushisisa kwe-welding carbon steel onqenqemeni lokusabalalisa ukupholisa kwe-weld kungena emaphethelweni e-strip.Ikakhulukazi eduze nemiphetho yomugqa ibe yi-CO nomoya-mpilo noma i-carbon dioxide, insimbi esele ngaphandle kwekhabhoni, umbala okhanyayo.

Ekusetshenzisweni kwe-high-frequency generator generator frequency generator kudlule izihibe ezintathu zepayipi elishiselwe: Amajeneretha anemvamisa ephezulu;ukushayela okuqinile;i-electronic high-frequency oscillator, futhi kamuva yathuthukiswa yaba yiluphu eyodwa.Kunezinhlobonhlobo zezindlela zokulungiswa kwamandla okukhipha i-oscillator ephezulu, njengama-auto-transformers, indlela yokusabela, umthetho we-thyristor.

Ipayipi lensimbi elifakwe imvamisa ephezulu lingase libe namaphutha ahlukahlukene.Isici ngasinye sinamagama amaningi ahlukene, awekho amagama ajwayelekile amukelwayo.Amagama alandelayo anikezwa isici, isici kubakaki elinye igama elivamile: (1) ukufakwa (i-oxide emnyama eshile);(2) i-pre-arc (i-oxide eshile emhlophe);ngaphansi (3) ukuhlanganisa (umthungo ovulekile);(4) ukuntuleka komphetho we-fusion (onqenqemeni.amagagasi);(5) Ukuhlanganisa okuphakathi akwanele (i-central cold welding);(6) ukushisela induku (ukushisela okubandayo);(7) i-cast welding (i-brittle weld);(8) i-stomata (i-pinhole);(9) gxuma welding.Lawa maphutha akuwona wonke kodwa amaphutha e-welding ajwayelekile kakhulu.
