I-Nugget shift iyinselelo evamile okuhlangatshezwana nayo ekushiseleleni indawo ye-inverter frequency, lapho indawo ye-weld nugget ichezuka endaweni yayo ehlosiwe.Ukushintsha kwe-Nugget kungathinta kabi ikhwalithi yokushisela, amandla ahlangene, nokusebenza kukonke.Lesi sihloko sihlose ukuhlola amasu namasu okunqoba ukushintshwa kwe-nugget ku-medium frequency inverter spot welding.
Lungiselela Amapharamitha Welding:
Ukulungiswa okufanele kwamapharamitha wokushisela kubalulekile ukuze kuncishiswe ukushintsha kwe-nugget.Imingcele ebalulekile okufanele icatshangelwe ihlanganisa i-welding current, isikhathi se-welding, amandla e-electrode, kanye ne-electrode geometry.Ukuthola inhlanganisela efanele yala mapharamitha kungasiza ukufeza i-weld nugget ezinzile futhi emaphakathi.Ukwenza izivivinyo zokuqala nokuhlola ikhwalithi yokushisela kungaqondisa inqubo yokwenza ipharamitha ngokugcwele.
Gcina Ukuqondanisa Kwe-Electrode:
Ukuqondanisa okunembile kwama-electrode kubalulekile ukuze kugwenywe ukushintsha kwama-nugget.Ukungaqondi kahle kungaholela ekusabalaliseni ukushisa okungalingani futhi kuphoqe ukugxila, kubangele ukuthi i-nugget ichezuke endaweni yayo ehlosiwe.Ukuhlolwa okuvamile nokulungiswa kokuqondisa kwe-electrode, okuhlanganisa ukugqoka ithiphu le-electrode kanye nokushintshwa, kungasiza ukugcina ukuma kwe-electrode efanele ngesikhathi sokushisela.
Lawula i-Electrode Force:
Ukusetshenziswa kwe-electrode force efanele kubalulekile ukuze kuzuzwe ama-weld nuggets angaguquki futhi agxile.Amandla anganele angabangela ukuthintana okungalungile phakathi kwezinto zokusebenza nama-electrode, okuholela ekushintsheni kwe-nugget.Ngakolunye uhlangothi, amandla amakhulu angabangela ukuguquguquka nokugudluzwa kwezingcezu zokusebenza, kuthinte ukwakheka kwe-nugget.Ukulinganisa amandla e-electrode ngokusekelwe kubukhulu bempahla kanye nezidingo ezihlanganyelwe zokushisela kuyadingeka ukuze kuncishiswe ukushintsha kwe-nugget.
Thuthukisa ukulungisa nokuhlanganisa:
Ukulungiswa okusebenzayo kanye nokubopha ama-workpieces kudlala indima enkulu ekuvimbeleni ukugudluka kwama-nugget.Ukuqondanisa okulungile nokulungiswa okuvikelekile kwama-workpieces kuqinisekisa ukuzinza ngesikhathi senqubo yokushisela, kunciphisa amathuba okususwa.Ukusebenzisa izinto ezilungiswayo ezifanele, amajigi, noma izindlela zokubopha ezenzelwe ijometri yesiqeshana sokusebenza kanye nokucushwa okuhlanganyelwe kungathuthukisa ukunemba kwe-weld futhi kunciphise ukushintshwa kwe-nugget.
Sebenzisa Amasistimu Wokuqapha Nezimpendulo:
Ukusebenzisa ukuqapha kwesikhathi sangempela nezinhlelo zokuphendula kungasiza ekutholeni nasekulungiseni ukushintshwa kwe-nugget ngesikhathi senqubo yokushisela.Ubuchwepheshe obahlukahlukene, njengamasistimu okubona, izinzwa zamandla, nezinzwa zokuthutha, zingase zisetshenziswe ukuze kuqashwe ikhwalithi yokushisela futhi kutholwe noma yikuphi ukuchezuka.Lawa masistimu ahlinzeka ngedatha ebalulekile yokwenziwa ngcono kwenqubo futhi anike amandla ukulungiswa okusheshayo ukuze kuncishiswe ukushintsha kwe-nugget.
Ukushintsha kwe-Nugget ku-medium frequency inverter spot welding kungabhekwana nayo ngokuphumelelayo ngokusebenzisa inhlanganisela yamasu.Ukuthuthukisa imingcele yokushisela, ukugcina ukuqondana kwe-electrode, ukulawula amandla e-electrode, ukuthuthukisa ukulungiswa, nokusebenzisa izinhlelo zokuqapha kuyizindlela ezibalulekile zokunqoba ukuguquguquka kwe-nugget.Ngokusebenzisa lezi zinyathelo, abakhiqizi bangathuthukisa ikhwalithi ye-weld, ubuqotho obuhlangene, nokusebenza okuphelele ekusebenzeni kwe-medium frequency inverter spot welding, ukuqinisekisa ukubekwa kwe-nugget okungaguquki nokunembile.
