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 yamazibuko asisigxina kufuneka ihlolwe ngokungenamkhethe ukuqinisekisa umgangatho wokuwelda wawo wonke umbhobho."IMigaqo 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.Iwelder 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.
