Kuphela ngokwazi ithonya Welding indlela Welding singakwazi ukusebenza kangcono futhi ulungisehigh-frequency longitudinal longitudinal umthungo ashiselwe ipayipi imishini yokwenzaukuze kuzuzwe ukusebenza kahle okuphezulu. Ake sibheke umthelela wezindlela zokushisela emishinini yamapayipi we-welding we-seam we-high-frequency eqondile namuhla.
Kunezindlela ezimbili zokuthihigh-frequency welding: ukuxhumana ne-welding kanye ne-induction welding.
Ukushisela othintana naye kusebenzisa ama-electrode ethusi axhumene nezinhlangothi zombili zepayipi lensimbi elizoshiselwa. Umsinga owenziwe unokungena okuhle. Imiphumela emibili ye-high-frequency current ikhuliswa ngenxa yokuxhumana okuqondile phakathi kwama-electrode ethusi ne-steel plate. Ngakho-ke, ukusebenza kahle kwe-welding ye-welding yokuxhumana Kuphezulu futhi kunokusetshenziswa kwamandla okuphansi, kusetshenziswa kabanzi ekukhiqizeni amapayipi anesivinini esikhulu nasezingeni eliphansi, futhi i-welding yokuxhumana iyadingeka lapho kukhiqizwa amapayipi ensimbi aminyene. Kodwa-ke, kunezinkinga ezimbili ekuxhumaneni kwe-welding: enye iwukuthi i-electrode yethusi ihlangene ne-steel plate, futhi igqoka ngokushesha; enye iwukuthi ngenxa yethonya le-flatness ye-steel plate surface kanye nokuqina konqenqema, ukuzinza kwamanje kwe-welding yokuxhumana kumpofu, futhi ama-burrs angaphakathi nangaphandle we-weld aphezulu kakhulu. , Ngokujwayelekile ayisetshenziswa uma kushiswa amapayipi anembobo ephezulu futhi anezindonga ezincane.
I-induction welding isonga ukujika okukodwa noma ngaphezulu kwamakhoyili wokungeniswa ngaphandle kwepayipi lensimbi ukuze lishiselwe. Umthelela wokujika okuningi ungcono kunokujika okukodwa, kodwa kunzima kakhulu ukukhiqiza nokufaka amakhoyili e-multi-turn induction. Ukusebenza kahle kuphezulu uma ibanga phakathi kwekhoyili yokungeniswa kanye nendawo yepayipi lensimbi lincane, kodwa kulula ukubangela ukukhishwa phakathi kwekhoyili yokungeniswa kanye nepayipi. Ngokuvamile, kuhle ukugcina igebe lika-5-8 mm phakathi kwekhoyili ye-induction kanye nendawo yepayipi yensimbi. Uma usebenzisa i-induction welding, njengoba ikhoyili ye-induction ingathintani nepuleti yensimbi, akukho ukugqoka nokukhala, futhi i-induction yamanje izinzile, okuqinisekisa ukuzinza kwe-welding. Izinga eliphezulu lepayipi lensimbi ngesikhathi sokushisela lihle, futhi i-weld seam ibushelelezi. Ukuze uthole ukunemba kwamapayipi, i-induction welding isetshenziswa ngokuyisisekelo.
