Kungakhathaliseki ukuba i-welding joint iphi, ngokwenene yingqokelela yamava e-welding.Kwi-novices, izikhundla ezilula ziyi-exercise esisiseko, ukuqala ngokujikeleza kunye nokuqhubela phambili kwiindawo ezimiselweyo.
I-welding yokujikeleza ihambelana ne-welding esisigxina kwi-welding ye-pipeline.I-welding elungisiweyo ithetha ukuba i-welding joint ayikwazi ukuhamba emva kokuba iqela lombhobho lilungelelaniswe, kwaye i-welding yenziwa ngokuhambelana nokutshintshwa kwendawo yokudibanisa (i-horizontal, vertical, up, and mid-level changes) ngexesha lenkqubo ye-welding.
Ukujikeleza i-welding port kukujikeleza i-welding port ngexesha lenkqubo ye-welding ukwenzela ukuba i-welder ikwazi ukwenza i-welding kwindawo efanelekileyo (enye ethe tye, ethe nkqo, phezulu nangaphantsi).
Enyanisweni, ukuthetha nje, i-welding edibeneyo yi-weld seam edityanisiweyo kwindawo, ehambelana nombhobho owenziwe kwangaphambili.
I-welding joint edibeneyo ithetha ukuba umbhobho awushukumi, kwaye i-welder yenza i-welding-round-round, ngakumbi xa indlela ye-welding iphezulu, indlela ye-welding ayilula ukuyisebenzisa, iimfuno zobugcisa be-welder ziphezulu, kwaye iziphene zixhomekeke kwenzeke.Ngokuqhelekileyo, ukwakhiwa kuqhutyelwa kwigalari yombhobho;
Izibuko elijikelezayo ngumbhobho onokuthi ujikelezwe.Indawo yokuwelda ngokusisiseko i-welding flat okanye i-welding ethe nkqo.Ukusebenza kwe-welding kulula kwaye kukho iziphene ezimbalwa.Ngokusisiseko yakhiwe phantsi okanye phantsi.
Ngexesha lokuhlolwa kwe-welding, ukwenzela ukuba kuthintelwe zonke izibuko ezijikelezayo ukuba zikhethwe ngokungenamkhethe ukuba zihlolwe, izinga lokupasa liphezulu, kwaye inxalenye ethile yamachweba angatshintshiyo kufuneka ihlolwe ngokungenamkhethe ukuqinisekisa umgangatho we-welding yawo wonke umbhobho."IiMigaqo yokuLawula iTekhnoloji yoKhuseleko loKhuseleko lweTekhnoloji-Imibhobho yoShishino" ichaza ukuba umlinganiselo wokubonwa kwee-welding joint joints awuyi kuba ngaphantsi kwe-40%.
Ngokubanzi, sisebenzisa izibuko elimisiweyo njengezibuko elisebenzayo.I-port esebenzayo yi-welding edibeneyo ye-welding yombhobho, kwaye icandelo lombhobho linokuthi lihanjiswe okanye lijikelezwe xa umbhobho wenziwa ngaphambili ngaphandle kwendawo.I-port esisigxina yi-site-installed port edibeneyo apho umbhobho awukwazi ukuhanjiswa okanye ukujikelezwa.
Kwinkcazo yombhobho womgama omde, ubizwa ngokuba yi "collision dead end", kwaye kufuneka ukuba "ukuhlolwa kwe-radiographic 100% kufuneka kwenziwe".I-angle ye-welding efile inzima, kwaye umgangatho we-welding akukho lula ukuqinisekiswa.
I-welds esisigxina inxulumene ne-welds ejikelezayo.
Ukudibanisa ukuwelda okujikelezayo kuthetha ukuba i-welder inokujikelezisa i-welding joint ngokuthanda ngokweyona angle ikhululekile yomsebenzi wokuwelda ngexesha lenkqubo ye-welding eyenziwe ngaphambili yombhobho, kunye nomgangatho we-welding uzinzile, ngoko ke i-welders ezifana nolu hlobo lwe-welding joint. .
Nangona kunjalo, ngenxa yeemfuno zeemeko zesayithi okanye iimeko ze-workpiece ngokwayo, i-welding joint of some workpieces inokulungiswa kuphela, into ebizwa ngokuba yi-welding joint joint.Xa i-welding joint edibeneyo ifakwe kwaye i-welding, kukho enye indlela yokudibanisa i-welding.Olu hlobo lwe-welding joint inzima ukuyidibanisa, kwaye umlinganiselo wovavanyo olungonakalisi uphezulu.
Kwezinye iinkcukacha zolwakhiwo lwemibhobho, umyinge wokufunyanwa kwe-weld engatshintshiyo uchazwe ngokucacileyo.Ngenxa yokuba ii-angles ze-welds ezisisigxina ziyahluka, i-welding manual iya kutshintsha, kwaye umgangatho we-welds uya kuchaphazeleka kwinqanaba elithile.Ngokomzekelo, i-welds esisigxina yeepayipi zetsimbi zifuna ukuba i-welders yenze yonke indawo, efuna iimfuno eziphezulu ze-welders.Ngokuqinisekileyo, ubuchule buphezulu kwaye inqanaba lobugcisa liphezulu.I-welder elungileyo ayinamsebenzi.
Kulawulo lolwakhiwo, inani lokuvuleka okuzinzileyo kufuneka lincitshiswe kangangoko kunokwenzeka.Ngakolunye uhlangothi, umgangatho we-welding unokulawulwa, kwaye ngexesha elifanayo, inani lokuvulwa kokuhlolwa lingancitshiswa ukunciphisa iindleko.
