I-Fusion Welding: Amandla Ayinhloko Wokushisela Izimboni

I-Fusion welding iyisigaba se-welding esisetshenziswa kakhulu. Ngezinzuzo zokukwazi ukujoyina amapuleti aminyene nokuba namandla aphezulu okushisela, sekuphenduke ubuchwepheshe obuyisisekelo emikhakheni efana nezakhiwo zensimbi, imikhumbi yokucindezela, kanye nokwakhiwa kwemikhumbi. Kuhlanganisa izindlela ezihlukahlukene ezifana ne-shielded metal arc welding (SMAW), i-gas metal arc welding (GMAW), kanye ne-laser welding, phakathi kwazo ezimbili zokuqala "izinhlobo ezivame ukusetshenziswa" ekukhiqizeni nasekugcinweni kwezimboni.

(I) Ishielded Metal Arc Welding (SMAW): I-Flexible futhi Elula "All-Rounder"

Ishielded metal arc welding (SMAW) iyindlela yokushisela eyisisekelo futhi eguquguqukayo. Incibilikisa izinsimbi ngokushisa kwe-arc phakathi kwe-electrode nendawo yokusebenza. Ngemishini elula kanye nemikhawulo ephansi yokusebenza, ifaneleka ngokukhethekile ukulungiswa kwendawo, ukukhiqizwa kwesiqephu esisodwa / inqwaba encane, kanye nokushisela izakhiwo eziyinkimbinkimbi.

1. Isimiso Esiyinhloko Nokubunjwa Kwezisetshenziswa

Isimiso: Ingubo engaphambili ekupheleni kwe-electrode iyasha ukuze yakhe igesi evikelayo, umoya ohlukanisayo. Ukushisa kwe-arc kuncibilikisa i-electrode core kanye ne-workpiece ukwakha ichibi elincibilikisiwe. Ngemuva kokupholisa, okusele kwe-coating kwenza i-slag ukuvikela insimbi ye-weld.

Izisetshenziswa: Umshini wokushisela we-AC noma we-DC arc, umnikazi we-welding electrode, ama-electrode welding (akhethwe ngokwesisekelo sensimbi; isb, ama-electrode E4303 avame ukusetshenziselwa insimbi ene-carbon ephansi), kanye nemishini yokuzivikela (isigqoko sokushisela, amagilavu afakiwe, izingubo zokushisela).

2. Amaphuzu Okusebenza Abalulekile

Ukulungiselela Ngaphambi Kokushisela: Ama-Electrode adinga ukomiswa ngokuvumelana nezidingo (150-200 ° C kuma-electrode ane-acidic, 350-400 ° C kuma-electrode ayisisekelo). Susa uwoyela, ukugqwala, nesikali se-oxide endaweni yokusebenza ukuze ugweme i-porosity; lungisa okwamanje ngokobukhulu bepuleti, ngokuvamile ulandela isimiso esithi "10-15A nge-mm yogqinsi lwepuleti" (isb., 60-90A ngamapuleti ensimbi angu-6mm).

Inqubo yokushisela: Base i-arc usebenzisa "indlela yokuklwebha" (efana nokushaya umentshisi) noma "indlela yokuthinta" (umthelela oqondile we-electrode kucezu lokusebenza). Lawula ubude be-arc ku-10-15mm (cishe izikhathi ezingu-0.8-1.2 ubukhulu be-electrode); gcina i-engeli engu-60-80 ° phakathi kwe-electrode kanye ne-workpiece, futhi uhambe ngesivinini esifanayo eduze kokuqondisa kokushisela. Lawula usayizi wechibi elincibilikisiwe libe izikhathi ezingu-1.5-2 ubukhulu be-electrode ukuze ugweme ukuqiniswa kwe-weld okubangelwa ichibi elincibilikisiwe elikhulu ngokwedlulele noma ukuntuleka kokuhlanganiswa ngenxa yechibi elincane elincibilikisiwe.

Ukwelashwa Kwangemva Kwe-Welding: Ngemva kokupholisa, sebenzisa isando se-slag ukuhlanza i-slag. Hlola indawo yokushisela ukuze uthole iziphambeko ezinjengokuqina, i-undercut, nokufakwa kwe-slag. Yenza ukuhlolwa okungabhubhisi uma kunesidingo.

3. Izicelo Ezijwayelekile Nemikhawulo

Izimo zohlelo lokusebenza: Izakhiwo zensimbi yokwakha, ukunakekelwa kwamapayipi, ukushisela ingxenye yemishini, ukwakhiwa kwebhuloho, njll., ezifanele kakhulu izimo zangaphandle noma lezo ezingenawo amandla kagesi angashintshi.

Imikhawulo: Ukusebenza kahle kokushisela okuphansi (ukusebenza ngokuzenzela), ikhwalithi yokushisela ithintwa kakhulu amakhono omqhubi, futhi ayifaneleki izinto ezenziwe nge-oxidized kalula njengama-alloys e-aluminium nezinsimbi ezingenasici.
