Litokisetso tsa Medium-Frequency Inverter Spot Welding

Medium-frequency inverter spot welding ke ts'ebetso ea ho tjheseletsa e sebelisoang haholo e tsebahalang ka bokhabane le ho nepahala ha eona. Ho etsa bonnete ba hore li-welds li atleha, ho hlokahala litokisetso tse nepahetseng pele u qala ts'ebetso ea ho cheselletsa. Sengoliloeng sena se tšohla mehato e hlokahalang le menahano ea ho itokisetsa ho tjheseletsa letheba ka mochini oa tjheseletsa oa maqhubu a mahareng a maqhubu.

1. Ho Hloekisa Mosebetsi: Pele ho tjheseletsa, ho bohlokoa ho hloekisa lisebelisoa tsa mosebetsi hantle. Lintho life kapa life tse silafatsang, tse kang mafome, oli, kapa litšila, li ka ama boleng ba li-welds hampe. Sebelisa mekhoa e nepahetseng ea ho hloekisa, joalo ka lisebelisoa tsa ho tlosa mafura kapa lisebelisoa tsa abrasive, ho tlosa litšila tse ka holim'a metsi le ho khothalletsa ho khomarela hantle.
2. Khetho ea Lisebelisoa: Ho bohlokoa ho khetha lisebelisoa tse loketseng bakeng sa ho cheselletsa letheba bakeng sa ho fihlela sephetho se lakatsehang. Nahana ka lintlha tse kang ho lumellana ha thepa, botenya, le conductivity. Etsa bonnete ba hore lisebelisoa tse tla kopanngoa li na le thepa e lumellanang ho etsa hore ho be le weld e matla le e tšoarellang.
3. Tlhophiso ea Electrode: Lokisetsa li-electrode ka hloko pele u tjheseletsa. Sheba libaka tsa li-electrode bakeng sa matšoao leha e le afe a ho khathala, ho senyeha kapa ho silafala. Haeba ho hlokahala, hloekisa kapa u nke sebaka sa li-electrode ho netefatsa ts'ebetso e nepahetseng. Tekanyetso e nepahetseng ea li-electrode le geometry le tsona li bohlokoa bakeng sa ho fihlela li-welds tse tsitsitseng le tsa boleng bo holimo.
4. Mekhahlelo ea Welding: Etsa qeto ea litekanyo tse loketseng tsa welding ho ipapisitsoe le botenya ba thepa, mofuta le matla ao u a batlang. Litekanyetso tsena hangata li kenyelletsa nako ea ho tjheseletsa, matla a electrode le nako ea ho tjheseletsa. Sheba lintlha tsa ts'ebetso ea welding kapa u etse liteko tsa pele ho fumana lintlha tse nepahetseng bakeng sa ts'ebeliso e itseng.
5. Welding Jig Setup: Hlophisa jig ea welding kapa fixture ho netefatsa boemo bo nepahetseng le ho tsamaisana ha lisebelisoa tsa mosebetsi. Jig e lokela ho tšoara li-workpieces ka mokhoa o sireletsehileng nakong ea welding ho thibela motsamao leha e le ofe kapa ho se lumellane ho ka senyang boleng ba weld.
6. Shielding Gas: Bakeng sa lits'ebetso tse ling, ts'ebeliso ea khase e sireletsang e ka thusa ho sireletsa letamo la weld tšilafalong ea sepakapaka le oxidation. Etsa qeto ea mofuta o nepahetseng le sekhahla sa phallo ea khase e sireletsang ho latela lisebelisoa tse cheselitsoeng 'me u buisane le litataiso kapa litsebi bakeng sa likhothaletso tse khethehileng.
7. Mehato ea Tšireletseho: Kamehla u etelletse pele polokeho ha u itokisetsa ho cheselletsa letheba. Netefatsa boteng ba lisebelisoa tsa ts'ireletso tsa motho (PPE), joalo ka lihelmete tse chesehang, liatlana le liaparo tsa ts'ireletso. Netefatsa ts'ebetso ea likarolo tsa ts'ireletso mochining oa welding, joalo ka likonopo tsa ho emisa ts'ohanyetso le lisebelisoa tsa ts'ireletso tse ngata haholo.

Litokisetso tse nepahetseng li bohlokoa bakeng sa ho fihlela li-welds tse atlehileng ka mochini oa tjheseletsa oa inverter oa maqhubu a mahareng. Ka ho hloekisa ka ho feletseng li-workpiece, ho khetha lisebelisoa tse loketseng, ho lokisa li-electrode, ho beha li-welding parameters ka nepo, ho hlophisa jig ea welding, ho nahanela tšebeliso ea khase e sireletsang, le ho etelletsa pele tšireletseho, li-welders li ka ntlafatsa ts'ebetso ea welding le ho etsa bonnete ba hore li-welds tsa boleng bo phahameng. Ho latela litataiso tsena ho tla kenya letsoho ts'ebetsong e sebetsang hantle le e ts'eptjoang ea ho cheselletsa libaka.
