Ukuwelda iintsimbi ezicimayo zibonakalisa imingeni ethile ngenxa yokuqina kwazo okuphezulu kunye nesidingo sokugcina iipropathi ezizifunayo zoomatshini emva kwe-welding.Kumxholo we-medium frequency inverter spot welding, eli nqaku ligxininisa kwiinkcukacha kunye nezikhokelo ze-welding steels quenchable.Ukuqonda kunye nokubambelela kule ngcaciso kubalulekile ekufezekiseni i-welds ethembekileyo kunye nekhwalithi ephezulu kwizicelo ezifuna intsimbi ecinyiweyo.
Ukukhethwa kwezinto:
Ukukhetha intsimbi ecinyiweyo efanelekileyo kwi-welding ibalulekile.Iintsimbi ezicimayo ezahlukeneyo zinemixholo eyahlukeneyo kunye neempawu zokuqina.Kubalulekile ukuqwalasela izinto ezifana namandla afunwayo, ukuqina, kunye neemfuno zonyango lobushushu emva kwe-weld xa ukhetha intsimbi ecinywayo kwisicelo esithile.
Uyilo oludibeneyo:
Uyilo oludibeneyo ludlala indima ebalulekileyo kwi-welding eyimpumelelo yeentsimbi ezicinywayo.Kubalulekile ukukhetha ukucwangciswa okuhlangeneyo okuqinisekisa ukulungelelaniswa okufanelekileyo, ukufikelela okwaneleyo kokubekwa kwe-electrode, kunye nokusabalalisa ubushushu obufanelekileyo.Uyilo oluqhelekileyo lokudityaniswa kweentsimbi ezicimayo lubandakanya imilenze yemilenze, i-butt joints, kunye ne-T-joints.
Ukufudumeza kwangaphambili kunye noLawulo loBuqondo obuphakathi:
Ukutshisa intsimbi ngaphambi kokuba i-welding incede ukunciphisa umngcipheko wokuqhekeka kunye nokunciphisa uxinzelelo olushiyekileyo.Ukushisa kwangaphambili kufuneka kunqunywe ngokusekelwe ekubunjweni kwentsimbi kunye nobukhulu.Ukongeza, ukulawula ubushushu be-interpass phakathi kokupasa kwe-welding kubalulekile ukukhusela ukupholisa okugqithisileyo kunye nokuqinisekisa ingqibelelo efanelekileyo ye-weld.
Imilinganiselo yeWelding:
Ukulungelelanisa i-welding parameters kubalulekile kwi-welding eyimpumelelo yeentsimbi ezicinywayo.Iiparameters ezifana ne-welding current, ixesha, amandla e-electrode, kunye nexesha lokupholisa kufuneka ilawulwe ngononophelo ukuze kuphunyezwe ukungena okufanelekileyo, ukudibanisa, kunye nokuchithwa kobushushu.Iiparamitha ze-welding zinokuhluka ngokuxhomekeka kwintsimbi ethile ecinyiweyo edibeneyo, ngoko ke kubalulekile ukubonisana neengcebiso zomenzi kwaye uqhube ii-welds zovavanyo ukuze kulungiswe iiparitha.
Unyango loBushushu lwasemva kweWeld:
Iintsimbi ezicimayo zihlala zifuna unyango lwe-post-weld ubushushu ukufezekisa izinto ezifunwayo zokwenza izinto.Oku kunokubandakanya iinkqubo ezinjengokuthambisa okanye ukucima nokuthambisa.Inkqubo ethile yonyango lokushisa kufuneka imiselwe ngokusekelwe kwibakala lensimbi kunye neemfuno zobunzima, amandla, kunye nokuqina.
Ulawulo lomgangatho kunye noVavanyo:
Ukuphumeza amanyathelo okulawula umgangatho kunye nokuqhuba uvavanyo olufanelekileyo lubalulekile ekuqinisekiseni ukunyaniseka kwee-welds kwiintsimbi ezicimayo.Iindlela zovavanyo ezingonakalisiyo ezinje ngokuhlolwa okubonwayo, uvavanyo lwe-ultrasonic, okanye uvavanyo lweradiyographic kufuneka zisetyenziswe ukukhangela naziphi na iziphene ezinokuthi zibe kho okanye ukungaqhubeki.
Ukuwelda iintsimbi ezicimayo kunye nomatshini we-welding ophakathi frequency inverter spot kufuna ukuthotyelwa kwemigaqo ethile kunye nezikhokelo.Ngokukhetha ngononophelo intsimbi ecimayo, ukuyila umdibaniso, ukulawula ukushisa kwangaphambili kunye nobushushu be-interpass, ukulungelelanisa imilinganiselo ye-welding, ukusebenzisa unyango lobushushu be-post-weld, kunye nokuqhuba ngokucokisekileyo ulawulo lomgangatho kunye novavanyo, i-welders inokufikelela kwiiwelds ezithembekileyo neziphezulu kwizicelo ezifuna ukucinywa. intsimbi.Ukulandela ezi zikhokelo kuya kuqinisekisa ukuba amacandelo adibeneyo agcina izinto ezifunwayo zemishini, ezifaka isandla ekusebenzeni ngokubanzi kunye nokuthembeka kweemveliso ezigqityiweyo.
