Cabanga ngezinto ezibonakalayo, izakhiwo zemishini kanye nokwakheka kwamakhemikhali we-weld material
1. I-Structural steel Welding, ngokuvamile icabangela isimiso samandla alinganayo, khetha ukuhlangabezana nezidingo zezakhiwo zemishini yezinto ezihlangene ze-welding.
2. Ngensimbi ye-carbon ephansi kanye nensimbi ephansi ye-alloy phakathi kwenhlanganisela yokushisela yensimbi engafani, ngokuvamile khetha izinto ezisetshenziswayo zokushisela ezihambisanayo nezinga eliphansi lamandla ensimbi.
3. Ukuze insimbi ukumelana nokushisa futhi insimbi engagqwali welding, ngaphezu kokucabangela amandla, kodwa futhi ucabangele ukwakheka kwamakhemikhali main of the weld metal kanye nokwakheka amakhemikhali we impahla umzali close.
4. Lapho ukwakheka kwamakhemikhali wento yomzali, njengekhabhoni noma isulfure, i-phosphorus nokunye ukungcola okuyingozi kuphezulu, kufanele ukhethe izinto ezisetshenziswayo zokushisela eziqinile zokumelana nokuqhekeka.Okufana ne-low hydrogen type welding consumables.
Cabanga ngezimo zokusebenza ze-welding kanye nokusetshenziswa kokusebenza
1. Izingxenye ezishiselwe esimweni somthwalo oguquguqukayo kanye nomthwalo womthelela, ngaphezu kwezidingo zokuqinisekisa amandla aqinile, amandla okukhiqiza, ukuqina komthelela, ipulasitiki yizidingo eziphakeme.Ngalesi sikhathi kufanele kukhethwe nge-low-hydrogen welding material.
2. Izingxenye ezishiselwe emithonjeni ebolayo, kufanele zihlukaniswe ohlotsheni lwemidiya, ukugxila, izinga lokushisa lokusebenza kanye nohlobo lokugqwala (ukugqwala okujwayelekile, ukugqwala kwe-intergranular, ukugqwala kwengcindezi, njll.), ukuze ukhethe izinto ezisetshenziswayo zokushisela insimbi engagqwali ezifanele.
3. Uma i-weld isebenza ngaphansi kwezimo zokuguga, kuyadingeka ukuhlukanisa phakathi kokuguga okuvamile noma ukuguga okunomthelela, ukuguga kwe-intermetallic noma ukuguguleka, ukugqokwa kwamazinga okushisa asekamelweni noma ukugqokwa ezingeni lokushisa eliphezulu, njll. Kufanele futhi kubhekwe ukuthi kufanele yini kusetshenzwe kumidiya egqwalayo. , ukuze ukhethe izinto ezisetshenziswayo zokushisela imbondela ezifanele.
4. Emazingeni okushisa aphansi noma izingxenye ze-welding eziphezulu zokushisa, kufanele ukhethe ukuqinisekisa ukuthi izinga lokushisa eliphansi noma izinga lokushisa eliphezulu lezakhiwo zemishini ye-welding material.
Cabanga ngobunkimbinkimbi kanye nezici zesakhiwo sezingxenye ezishiselwe, uhlobo oluhlanganisiwe oluhlanganisiwe, njll.
1. Ijamo eliyinkimbinkimbi noma ukushuba okukhulu kwezingxenye ezishiselwe, ngenxa yensimbi yayo yokushisela ekupholiseni okupholisa ukucindezeleka kwangaphakathi okukhiqizwa ukuqhekeka okukhulu, okulula ukukhiqiza.Ngakho-ke, kuyadingeka ukusebenzisa izinto ezisetshenziswayo zokushisela ezinokumelana okuhle nokuqhekeka, njengenduku ye-welding ephansi ye-hydrogen, induku yokushisela yokuqina okuphezulu.
2. Ngamalunga athile anama-bevel amancane, noma amalunga anokulawula okuqinile kokungena kwezimpande, izinto ezisetshenziswayo zokushisela ezinokujula okukhulu kokuhlanganiswa noma ukungena kufanele kusetshenziswe.
3. Ngenxa yezingqinamba zezinye izingxenye ze-welding okunzima ukuzihlanza, kufanele zicabangele ukusetshenziswa kokugqwala, i-oxidation kanye nokusabela kwamafutha akuzweli ku-welding material, njenge-acid welding rod, ukuze kungakhiqizi amaphutha njenge-porosity.
Cabanga ngesimo sendawo ye-weld
Ezinye izinto ezisetshenziswayo zokushisela zifaneleka kuphela ukushisela endaweni ethile, ezinye izikhundla zingasebenzi kahle uma zishisela, ezinye izinto ezisetshenziswayo zokushisela ziyakwazi ukushisela ezindaweni ezahlukahlukene, izici zesikhundla sokushisela kufanele zicatshangelwe lapho kukhethwa.
Cabangela izimo zokusebenza zokushisela, indawo yokusebenza
1. Azikho izikhathi zomshini wokushisela we-DC, kufanele kusetshenziswe izinto zokushisela ze-AC ne-DC ezimbili.
2. Enye insimbi (njengensimbi ekwazi ukumelana nokushisa kwe-pearlite) idinga ukwelashwa kokushisa kwe-post-weld, kodwa ngokwezimo zemishini noma ngezingqinamba zayo zesakhiwo futhi ayikwazi ukwenziwa, kufanele ikhethwe ngokwakheka kwamakhemikhali ensimbi okuyisisekelo. izinto ezisetshenziswayo zokushisela ezihlukene (ezifana nezinto ezisetshenziswayo zokushisela insimbi engagqwali ye-austenitic), zingakhululwa ekwelashweni kokushisa kwangemva kokushisela.
3. Kufanele kusekelwe ezimweni zendawo yokwakha, njengokusebenza kwensimu, indawo yokusebenza ye-welding, njll.
4. Ezindaweni lapho kungasetshenziswa kokubili ama-electrode okushisela ane-acidic kanye ne-alkaline, ama-electrode wokushisela ane-asidi kufanele asetshenziswe ngangokunokwenzeka ngenxa yezidingo eziphakeme zama-alkaline welding electrode amasu okusebenza nokulungiselela ukwakha.
Cabanga ngezomnotho zokushisela
1. Zama ukusebenzisa i-welding consumables engabizi, inqobo nje uma ukusebenza kokusetshenziswa kuqinisekisiwe.
2. Izinto ezisetshenziswayo ze-welding ezihlukene zingasetshenziselwa ama-welds ayisisekelo nakwesibili anezidingo ezahlukene zokusebenza, futhi ungaphishekeli ukusebenza okugcwele kwe-welding consumables unilaterally.
Cabangela ukusebenza kahle kwe-welding
Kuzakhiwo ezinomthwalo omkhulu wokushisela, izinto ezisetshenziswayo zokushisela ezisebenza kahle kakhulu kufanele zisetshenziswe ngangokunokwenzeka lapho zitholakala, njengocingo lokushisela, induku yokushisela i-iron powder, induku yokushisela yensimbi engenasici esebenza kahle, njll.
