High-frequency welding ndiko kushandiswa kweganda rekuita kuti simba remazuva ano riwedzere pamusoro pebasa rekushanda;Iyo yepedyo mhedzisiro inoshandiswa kudzora chinzvimbo uye huwandu hweiyo yakakwira frequency ikozvino kuyerera nzira.Iko kumhanya kweiyo ikozvino inokurumidza kwazvo, inogona kupisa mupendero wesimbi iri padyo munguva pfupi, kunyunguduka, uye kuona iyo docking kuburikidza neextrusion imwe neimwe ine zvayakanakira, asi zvakare ine zvikanganiso zvayo.Zvinowanzodikanwa kuongorora sarudzo dzakananga maererano nemamiriro ezvinhu chaiwo.
Maitiro ekugadzira Magetsi Resistance Welding (ERW) Pipe ndeaya anotevera:
Vhura ndiro inoongorora → Kutwasanura kugaya → kucheka kuumba → Kuchekwa kwebutt welding → Kuongorora nekuona → Kuongorora kwepamhepo → Kuongorora kweX-ray → Kudzvanya bvunzo → Flat chamfering → Kuongorora kwekupedzisira
Bare pombi kana Nhema / Varnish coating (yakagadzirirwa);
mumasumbu kana makasununguka;
Zvose zvinopera nevadziviriri vekupedzisira;
Magumo akajeka, bevel end (2"uye pamusoro ane bevel ends, degree: 30 ~ 35 °), yakarukwa uye yakabatana;
Kumaka.
