Na ua tseba ka Mochini oa ho Welding oa Dynamic Resistance Curve ho Medium Frequency Inverter Spot Welding Machine?

The dynamic resistance curve ke tšobotsi ea bohlokoa mecheng ea welding ea maqhubu a mahareng a maqhubu.E emela kamano pakeng tsa hona joale welding le ho theoha ha motlakase ho pholletsa le li-electrode nakong ea ts'ebetso ea welding.Ho utloisisa curve ena ho bohlokoa bakeng sa ho ntlafatsa liparamente tsa welding le ho netefatsa li-welds tsa boleng bo holimo.Sehloohong sena, re tla hlahloba mohopolo oa "dynamic resistance curve" le bohlokoa ba eona lits'ebetsong tsa welding.

1. Tlhaloso ea Matla a Resistance Curve: Mokokotlo o matla oa ho hanyetsa o bonts'a khanyetso e teng hang-hang nakong ea ts'ebetso ea welding.E fumanoa ka ho rera hona joale oa welding khahlanong le ho theoha ha motlakase ho pholletsa le li-electrode.Mokokotlo ona o fana ka lintlha tsa bohlokoa mabapi le boitšoaro ba motlakase le mocheso oa weldment, e leng ho lumellang hore ho be le taolo e nepahetseng le ho lekola ts'ebetso ea ho cheselletsa.
2. Lintlha tse Amang Lekhalo le Matla la Resistance: a.Thepa ea Material: Mokokotlo o matla oa ho hanyetsa o fapana ka lisebelisoa tse fapaneng ka lebaka la phapang ea conductivity ea motlakase, conductivity ea mocheso le mocheso o qhibilihang.Ho bohlokoa ho nahana ka thepa ea thepa ha u toloka lekhalo le ho khetha li-parameter tse nepahetseng tsa welding.b.Tlhophiso ea Electrode: Sebopeho, boholo, le thepa ea li-electrode li susumetsa sebaka sa ho kopana le ho qhalana ha mocheso, e leng se amang sekhahla se matla sa ho hanyetsa.Khetho e nepahetseng le tlhokomelo ea li-electrode li bohlokoa bakeng sa ho fumana liphetho tse tsitsitseng le tse tšepahalang tsa welding.c.Li-Parameters tsa Welding: Mokokotlo o matla oa ho hanyetsa o na le maikutlo a ho feto-fetoha ha mekhahlelo ea welding joalo ka welding current, electrode force, le time welding.Ho fetola liparamente tsena ho ka fetola sebopeho le litšoaneleho tsa curve, ho lumella ho ntlafatsa ts'ebetso ea welding.
3. Bohlokoa ba Mokokotlo o Matla oa Resistance: a.Tlhokomelo ea Ts'ebetso: Lekhalo le matla la ho hanyetsa le fana ka maikutlo a nako ea nnete mabapi le boleng le botsitso ba ts'ebetso ea welding.Ho kheloha ho tsoa ho sebopeho se lebelletsoeng sa curve ho ka bonts'a mathata a joalo ka ho se kopane ha li-electrode, ho se hlahise mocheso o lekaneng, kapa ho kopanya lintho tse sa nepahalang.b.Ntlafatso ea Paramethara: Ka ho sekaseka lebelo le matla la ho hanyetsa, li-parameter tse nepahetseng tsa welding li ka ikemisetsa ho fihlela litšobotsi tse lakatsehang tsa weld, joalo ka botebo ba ho kenella, boholo ba nugget le matla a kopaneng.Ho lokisa liparamente tsa welding tse ipapisitseng le tlhahlobo ea curve ho ntlafatsa taolo ea ts'ebetso le ho netefatsa boleng bo tsitsitseng ba weld.c.Ho Fumana Phoso: Liphetoho tsa tšohanyetso kapa liphapang ka har'a curve e matla ea ho hanyetsa li ka bonts'a moaparo oa li-electrode, tšilafalo ea thepa, kapa liphoso tse ling.Ho beha leihlo curve ho u fa monyetla oa ho lemoha litaba tsena kapele, ho thusa ho lokisoa ka nako kapa ho etsa mehato ea ho lokisa ho thibela bofokoli ba welding.
4. Mekhoa ea ho lekanya: Ho ka sebelisoa mekhoa e fapaneng ho lekanya le ho sekaseka lebelo le matla la ho hanyetsa, ho kenyeletsoa ho lekola ho theoha ha motlakase, mekhoa ea hajoale ea ho utloa, le lits'ebetso tsa ho fumana data.Mekhoa ena e ts'oara boits'oaro ba motlakase hang-hang ba ts'ebetso ea welding le ho thusa ho hlahisa sekhahla se matla sa ho hanyetsa.

The dynamic resistance curve in medium frequency inverter spot welding machine ke sesebelisoa sa bohlokoa sa ho utloisisa boitšoaro ba motlakase le mocheso oa weldment.E sebetsa e le tataiso bakeng sa ho ntlafatsa liparamente tsa welding, ho lekola botsitso ba ts'ebetso, le ho bona liphoso tse ka bang teng.Ka ho sebelisa tlhahisoleseling e fanoeng ke sekhahla se matla sa ho hanyetsa, bahlahisi ba ka fihlela li-welds tse tsitsitseng le tsa boleng bo holimo, ba ntlafatsa tlhahiso e akaretsang le ts'epo ea sehlahisoa lits'ebetsong tsa welding.
