Tlhaloso e Tebileng ea Welding Curve Curve ka Medium Frequency Inverter Spot Welding Machines

Curve ea hona joale ea welding e bapala karolo ea bohlokoa ts'ebetsong ea welding ea mechini ea welding ea maqhubu a mahareng. E emela ho fapana ha welding hona joale ha nako e ntse e feta 'me e na le tšusumetso e kholo ho boleng le litšobotsi tsa weld e hlahisoang. Sengoliloeng sena se fana ka tlhaloso e qaqileng ea curve ea hona joale ea welding mochining oa tjheseletsa oa maqhubu a mahareng a maqhubu a inverter.

1. Current Ramp-Up: Mokokotlo oa hona joale oa tjheseletsa o qala ka mokhahlelo oa ho nyoloha, moo motlakase o nyolohang butle-butle ho tloha ho lefela ho ea ho boleng bo reriloeng esale pele. Karolo ena e lumella ho thehoa ha puisano e tsitsitseng ea motlakase pakeng tsa li-electrode le li-workpieces. Nako le sekhahla sa ramp-up li ka fetoloa ho ipapisitsoe le thepa, botenya, le liparamente tsa welding tse lakatsehang. Tsela e laoloang le e boreleli ea hona joale e thusa ho fokotsa ho hasana le ho finyella sebopeho se tsitsitseng sa weld nugget.
2. Welding Current Pulse: Ho latela ramp-up ea hajoale, hona joale oa welding o kena mohatong oa pulse. Nakong ena, ho sebelisoa motlakase o sa khaotseng bakeng sa nako e itseng, e tsejoang e le nako ea ho cheselletsa. Leqhubu la hona joale la tjheseletsa le hlahisa mocheso libakeng tseo ho kopanang ho tsona, ho baka ho qhibiliha ha libaka le ho tiisa ho latelang ho etsa nugget ea weld. Nako ea ho tjheseletsa pulse hona joale e khethoa ke lintlha tse kang mofuta oa thepa, botenya, le boleng ba weld bo lakatsehang. Taolo e nepahetseng ea nako ea pulse e etsa bonnete ba hore ho na le mocheso o lekaneng oa mocheso le ho qoba ho chesa kapa ho chesa li-workpieces.
3. Ho Bola ha Hona Joale: Ka mor'a ho tjheseletsa ha pulse hona joale, hona joale butle-butle ho senyeha kapa ho fokotseha ho khutlela ho zero. Mokhahlelo ona ke oa bohlokoa bakeng sa ho tiea ho laoloang le ho pholisa ha chesele nugget. Sekhahla sa ho bola ha joale se ka fetoloa ho ntlafatsa sekhahla sa ho pholisa le ho thibela ho kenya mocheso o feteletseng libakeng tse haufi, ho fokotsa ho khopama le ho boloka thepa ea thepa.
4. Post-Pulse Current: Lits'ebetsong tse ling tsa tjheseletsa, mochini oa morao-rao o sebelisoa ka mor'a hore motlakase o be teng le pele ho senyeha ho feletseng ha hona joale. Mokotla oa morao-rao o thusa ho hloekisoa ha li-weld nugget le ho ntlafatsa thepa ea eona ea mochine ka ho khothalletsa ho hasana ha boemo bo tiileng le ho ntlafatsa lijo-thollo. Nako le boholo ba hona joale ka mor'a pulse li ka fetoloa ho latela litlhoko tse khethehileng tsa welding.

Ho utloisisa curve ea hona joale ea welding mochining oa welding oa frequency inverter spot welding ho bohlokoa bakeng sa ho fihlela li-welds tsa boleng bo holimo le tse tšepahalang. The ramp-up e laoloang, pulse ea hona joale ea welding, ho senyeha ha hona joale, le ts'ebeliso e ka 'nang ea e-ba teng ea morao-rao ea morao-rao e kenya letsoho ts'ebetsong ea ho tjheseletsa ka kakaretso, ho netefatsa ho kenya mocheso o nepahetseng, ho tiisa le ho pholile. Ka ho ntlafatsa curve ea hona joale ea welding ho ipapisitse le thepa, botenya, le litšoaneleho tse lakatsehang tsa weld, bahlahisi ba ka fihlela sephetho se ts'oanang le se khotsofatsang lits'ebetsong tsa bona tsa tjheseletsa.
