Yiziphi izici ezihlobene nomthelela wokugcina amandlaumshini wokushisela indawo? Vumela's sibheke kafushane: 1. Welding current; 2. Isikhathi sokushisela; 3. Umfutho we-electrode; 4. Electrode izinto zokusetshenziswa.
1. Umthelela we-welding current
Kungabonakala kufomula ukuthi umthelela wamanje ekukhiqizeni ukushisa mkhulu kunokokubili ukumelana nesikhathi. Ngakho-ke, ipharamitha okufanele ilawulwe ngokuqinile ngesikhathi senqubo yokushisela indawo. Izimbangela eziyinhloko zezinguquko zamanje ukudlidliza kwegridi kagesi kanye nomshini wokushisela we-AC wesibili izinguquko zesekethe ye-impedance. Ukushintsha kokuphazamiseka kubangelwa izinguquko ku-loop geometry noma ukwethulwa kwamanani ahlukene ensimbi kazibuthe ku-loop yesibili. Emishini yokushisela ye-DC, i-impedance yesibili yesifunda iyashintsha futhi ayinawo umthelela osobala okwamanje.
Ngaphandle kwenani le-welding yamanje, ukuminyana kwamanje nakho kunethonya elikhulu ekushiseni. Ngokuvala amalunga ashiselwe kanye nokwanda kwendawo yokuxhumana ye-electrode noma usayizi weqhubu ngesikhathi sokushisela, ukuminyana kwamanje kanye nokushisa kwe-welding kuzoncishiswa, okuholela ekwehleni okukhulu kwamandla ahlangene.
2. Umthelela wesikhathi sokushisela
Ukuze uqinisekise usayizi we-nugget namandla ahlangene we-solder, isikhathi se-welding kanye ne-welding yamanje ingahambisana phakathi komkhawulo othile. Ukuze uthole amalunga e-solder ngamandla athile, ungasebenzisa isikhathi esikhulu samanje nesifushane (isimo esiqinile, esaziwa nangokuthi izinga eliqinile), noma ungasebenzisa zamanje ezincane nesikhathi eside (isimo esibuthakathaka, esaziwa nangokuthi izinga elibuthakathaka). Ukukhethwa kwezimo eziqinile noma ezibuthakathaka kuncike emsebenzini wensimbi, ubukhulu bayo kanye namandla omshini wokushisela osetshenzisiwe. Nokho, kusenemikhawulo ephezulu nephansi yamanje kanye nesikhathi esidingekayo ezinsimbi ezinezakhiwo nobukhulu obuhlukene. Ngalé kwalo mkhawulo, i-nugget efanelekayo ngeke yakheke.
3. Ithonya lokucindezela kwe-electrode
Ukucindezela kwe-electrode kunomthelela omkhulu ekumelaneni okuphelele kuka-R phakathi kwama-electrode amabili. Njengoba umfutho we-electrode ukhula, u-R wehla kakhulu. Nakuba i-welding current ikhula kancane ngalesi sikhathi, ayinakuthinta ukunciphisa ukukhiqizwa kokushisa okubangelwa ukunciphisa R. Ngakho-ke, amandla okuhlanganiswa kwe-solder ahlala ehla njengoba ingcindezi ye-electrode ikhula. Ngenkathi ukhulisa ingcindezi ye-electrode, khulisa i-welding current noma wandise isikhathi sokushisela ukuze unxephezele umphumela wokumelana okuncishisiwe futhi ugcine amandla e-solder joint joint njalo. Ukusetshenziswa kwalesi simo se-welding kuzosiza ukuthuthukisa ukuzinza kwamandla ahlangene we-solder. Uma ingcindezi ye-electrode incane kakhulu, izodala i-spatter futhi inciphise amandla okuhlangana kwe-solder.
4. Ithonya lomsebenzi wezinto zokusetshenziswa kwe-electrode
Kusukela endaweni yokuxhumana ye.i-electrode inquma ukuminyana kwamanje, i-resistivity kanye ne-thermal conductivity ye-electrode material ihlobene nokukhiqizwa nokuchithwa kokushisa, ngakho-ke ifomu kanye nempahla ye-electrode kunomthelela omkhulu ekwakhekeni kwama-nuggets. Nge-deformation kanye nokugqoka kwekhanda le-polarization kagesi, indawo yokuxhumana izokhula futhi amandla okuhlangana kwe-solder azokwehla.
