Ukuqhekeka kwendawo ye-Weld kunokuba ngumba ocelomngeni ojongene nawo ngexesha lokusebenza koomatshini bokuwelda bamantongomane. Ukunyaniseka kwejoyinti ye-weld iyancipha xa iindawo ze-weld zisilela ukumelana nemithwalo esetyenzisiweyo okanye uxinzelelo lwendalo. Kweli nqaku, siza kuphonononga izizathu eziqhelekileyo zokuqhekeka kwendawo ye-weld kwaye sibonise izisombululo ezisebenzayo ukulungisa le ngxaki.
- Oonobangela boKuqhekeka kweWeld Spot:
- Ukungena kwe-Weld eyaneleyo: Ukufakwa kobushushu obunganelanga okanye uxinzelelo olungonelanga ngexesha le-welding kunokukhokelela ekudibaneni okungaphelelanga, okubangela ukuba iindawo ezibuthathaka ze-weld zithande ukuphuka.
- Ukungahambelani kwezinto eziphathekayo: Izinto ezingahambelaniyo kunye ne-coefficients yokwandiswa kwe-thermal eyahlukeneyo inokubangela ukugxininiswa koxinzelelo kunye nokukhuthaza ukuphuka kwi-weld interface.
- Ungcoliseko lwe-Electrode: Ii-electrode ezingcolisekileyo zinokuzisa ukungcola kwi-weld pool, zenza buthathaka iipropathi ze-joint mechanical kwaye zikhokelela ekungaphumeleli kwangaphambi kwexesha.
- Ubungakanani be-Weld Spot kunye neMilo: Ijometri yendawo ye-weld engafanelekanga, efana nobubanzi obugqithisileyo okanye imilo engaqhelekanga, inokubangela ukuxinzelela kwamanqaku kunye nokukhuthaza ukuqaliswa kokuphuka.
- IiParameters ze-Welding eziphuculweyo: Ukuphucula i-welding parameters kubalulekile ukujongana nokuphuka kwendawo ye-weld. Ukonyusa i-welding yangoku, uxinzelelo lwe-electrode, kunye nexesha le-welding kunokuphucula ukungena kwe-weld kunye nokudibanisa, okukhokelela kwiindawo eziqinileyo ze-weld.
- Ukukhetha izinto eziphathekayo: Ukukhetha izinto ezihambelanayo ezineempawu ezifanayo zoomatshini kunye ne-coefficients yokwandisa i-thermal kunokunciphisa uxinzelelo kunye nokuphucula ingqibelelo edibeneyo ye-weld.
- Ukugcinwa kwe-Electrode kunye nokuCoca: Ukugcinwa rhoqo kunye nokucocwa kwee-electrode kubalulekile ukuthintela ukungcoliseka ngexesha le-welding. Ukunyamekela okufanelekileyo kwe-electrode kuqinisekisa ukubunjwa kwendawo ye-weld ehambelanayo kunye nomgangatho ophezulu.
- Uyilo lwe-Weld Spot kunye noHlolo: Uyilo oluchanekileyo lweendawo ze-weld, kubandakanywa ubungakanani kunye nokuma, kunokunceda ukusabalalisa uxinzelelo ngokulinganayo kunye nokunciphisa umngcipheko wokuphuka. Ukongeza, ukwenza uhlolo rhoqo kunye novavanyo olungonakalisiyo kunokubona iziphene ezinokwenzeka kwangoko, ukuvumela amanyathelo okulungisa ngexesha.
- Unyango lwe-Annealing kunye ne-Post-Weld: Ukusebenzisa unyango lwe-annealing okanye emva kwe-weld lunokunceda ukukhulula uxinzelelo olushiyekileyo kwi-weld joint, ukuphucula i-ductility yayo kunye nokuchasana nokuphuka.
Ukuthintelwa kwe-weld spot fracture kumatshini we-welding welding kufuna indlela ebanzi equka ukulungelelanisa imilinganiselo ye-welding, ukukhetha izinto ezihambelanayo, ukugcina i-electrodes, kunye nokuphumeza amanyathelo okulawula umgangatho osebenzayo. Ngokujongana noonobangela bengcambu ye-weld spot fracture, abavelisi banokuqinisekisa ukuveliswa kwamalungu e-weld aqinileyo kwaye athembekileyo, anegalelo ekusebenzeni ngokubanzi kunye nokhuseleko lwamacandelo adibeneyo kumashishini ahlukeneyo.
