Ama-pores emthungo we-weld ayinkinga evamile yekhwalithi ngesikhathii-robot welding. Ukuba khona kwama-pores kungaholela ekwehleni kwamandla ama-welds, futhi kubangele nokuqhekeka nokuqhekeka. Izizathu eziyinhloko zokwakhiwa kwama-pores kuma-weld we-robot zihlanganisa okulandelayo:
1. Ukuvikelwa kwegesi okungalungile:
Ngesikhathi senqubo yokushisela, ukuhlinzekwa kwamagesi avikelayo (njenge-argon, i-carbon dioxide, njll.) akwanele noma akulingani, okuhluleka ukuhlukanisa ngokuphumelelayo i-oxygen, i-nitrogen, njll. emoyeni, okuholela ekuxubeni kwegesi echibini lokuncibilika futhi ukwakheka kwezimbotshana.
2. Ukuphathwa kabi kwendawo yezinto zokushisela nezinto eziyisisekelo:
Kukhona ukungcola okufana namabala kawoyela, ukugqwala, umswakama, nezikali ze-oxide ebusweni bempahla yokushisela noma isisekelo sensimbi. Lokhu kungcola kuyabola emazingeni okushisa aphezulu okushisela ukuze kukhiqizwe igesi, engena echibini elincibilikisiwe bese kwakheka izimbotshana.
3. Imingcele yenqubo yokushisela engafanele:
Uma isivinini samanje, i-voltage, nesivinini sokushisela siphezulu kakhulu noma siphansi kakhulu, okuholela ekunyakazeni okunganele kwechibi lokuncibilika kanye nokungakwazi kwegesi ukuphuma ngokushelela; Noma uma i-engeli evuthelayo yegesi yokuvikela ingalungile, ingase ithinte umphumela wokuvikela igesi.
4. Idizayini yokushisela engenangqondo:
Uma igebe phakathi kwe-weld seams likhulu kakhulu, i-fluidity yensimbi ye-pool encibilikile impofu, futhi igesi kunzima ukuyikhipha; Noma ukwakheka kwe-weld seam kuyinkimbinkimbi, futhi igesi akulula ukuphunyuka ekujuleni kwe-weld seam.
5. Umswakama ophezulu endaweni yokushisela:
Umswakama osemoyeni ubola ube yigesi ye-hydrogen emazingeni okushisa aphezulu okushisela, onokuncibilika okuphezulu echibini elincibilikisiwe futhi awukwazi ukuphuma ngesikhathi phakathi nenqubo yokupholisa, yakhe izimbotshana.
Izinyathelo zokuxazulula inkinga ye-porosity ekushiseni kwamarobhothi zimi kanje:
1. Lungiselela ukuvikelwa kwegesi:
Qinisekisa ukuthi ukuhlanzeka kwegesi yokuvikela kuhlangabezana nezinga, izinga lokugeleza lilinganiselwe, futhi ibanga phakathi kwe-nozzle ne-weld seam lifanelekile, okwenza ukuvikela okuhle kwamakhethini emoyeni.
●Sebenzisa ukwakheka kwegesi okufanelekile nesilinganiso sokuxuba, njengokusebenzisa izinduku zokushisela i-hydrogen ephansi noma ephansi kakhulu nezintambo, ukuze unciphise umthombo wegesi ye-hydrogen.
2. Ukwelashwa kwendawo okuqinile:
Hlanza ngokuphelele ubuso be-impahla yokushiselakanye nesisekelo sensimbi ngaphambi kokushisela, susa ukungcola okufana nowoyela, ukugqwala, nomswakama, futhi wenze ukwelashwa kwangaphambi kokushisisa uma kudingekile.
Ezindaweni lapho umswakama ungase ube khona ngesikhathi senqubo yokushisela, thatha izinyathelo zokomisa, ezifana nokusebenzisa isomisi se-weld seam noma ukushisa kuqala umsebenzi.
3. Lungisa amapharamitha wenqubo yokushisela:
Khetha ijubane elifanele lamanje, i-voltage, kanye nesivinini sokushisela ngokusekelwe kumpahla yokushisela, impahla eyisisekelo, nendawo yokushisela ukuze uqinisekise ukunyakaziswa okumaphakathi nesikhathi sokuphuma kwegesi echibini elincibilikisiwe.
Lungisa i-engeli yokuphephetha yegesi evikelayo ukuze uqinisekise ukuthi igesi ivala ngokulinganayo i-weld seam.
4. Thuthukisa idizayini yokushisela:
Lawula igebe le-weld seam phakathi kwebanga elifanelekile ukuze ugweme ukuba likhulu kakhulu noma libe lincane kakhulu.
Kuma-welds ayinkimbinkimbi, izindlela ezinjengokushisela okuhlukanisiwe, insimbi yokugcwalisa esethiwe, noma ukushintsha ukulandelana kokushisela kungasetshenziswa ukuthuthukisa izimo zokuphuma kwegesi.
5. Lawula indawo yokushisela:
Zama ukushisela endaweni eyomile futhi engenawo umoya ukuze ugweme umswakama oweqile.
Ezindaweni lapho umswakama ungenakulawulwa khona, izinyathelo ezifana nokusebenzisa i-hygroscopics kanye nokushisisa komthungo we-welding kungabhekwa njengokunciphisa umthelela womswakamo.
6. Ukuqapha nokulawula ikhwalithi:
Hlola njalo ukusebenza kwemishini yokushisela, njengamamitha okugeleza kwegesi, imibhobho yezibhamu zokushisela, njll., ukuze uqinisekise isimo sabo esihle sokusebenza.
Ukuqapha isikhathi sangempela senqubo yokushisela, njengokusebenzisa uhlelo lokuqapha inqubo yokushisela, ukuthola ngokushesha nokulungisa amapharamitha angavamile.
Yenza ukuhlola okungonakali (njengokuhlola i-ultrasonic, ukuhlolwa kwe-radiographic, njll.) ngemva kokushisela ukuze uthole ngokushesha futhi uphathe ama-welds aqukethe i-porosity. Ukusetshenziswa okuphelele kwalezi zinyathelo ezingenhla kunganciphisa ngempumelelo ukukhiqizwa kwama-pores kuma-welds amarobhothi futhi kuthuthukise ikhwalithi yokushisela.
Izimbangela ze-porosity kuma-weld we-robot zihlanganisa ukungcoliswa kwendawo yezinto zokushisela, ukuvikelwa kwegesi okwanele, ukulawulwa okungalungile kwe-welding current kanye ne-voltage, kanye nesivinini sokushisela ngokweqile. Ukuze sixazulule le nkinga, kudingeka sithathe izinyathelo ezihambisanayo, okuhlanganisa ukusebenzisa izinto zokushisela ezihlanzekile, ukukhetha amagesi okuvikela ngokunengqondo nokulawula izinga lokugeleza, ukubeka imingcele yokushisela ngokunengqondo, nokulawula isivinini sokushisela ngokuvumelana nesimo. Kuphela ngokubhekana nezici eziningi ngasikhathi sinye lapho singakwazi ukuvimbela ngempumelelo futhi sixazulule inkinga ye-porosity ekushiseni kwamarobhothi, futhi sithuthukise ikhwalithi yokushisela.
