E bua ka matla a pele a sebelisoang ho li-workpieces pele ts'ebetso ea 'nete ea welding e qala. Preload e bapala karolo ea bohlokoa ho netefatsa ho tsamaisana ho nepahetseng, ho ikopanya le botsitso lipakeng tsa li-electrode le li-workpieces, ka hona ho kenya letsoho ho boleng ba kakaretso le katleho ea ts'ebetso ea welding. Sengoliloeng sena se fana ka kakaretso ea ho jara mochini oa welding oa frequency frequency inverter spot.
- Tlhaloso: Ho roala esale pele ka tjheseletsa sebakeng ho bolela matla a qalang a sebelisoang ke li-electrode tsa welding holim'a lisebelisoa pele motlakase o kengoa. Ke matla a tsitsitseng a thehang ho kopana le ho lumellana pakeng tsa li-electrode le li-workpieces, ho li lokisetsa bakeng sa ts'ebetso e latelang ea tjheseletsa. Ho jara pele hangata ho sebelisoa nako e khuts'oane, ho netefatsa boemo bo nepahetseng le botsitso ba lisebelisoa.
- Bohlokoa ba Preload: Preload e sebeletsa merero e 'maloa ea bohlokoa mochining oa welding oa frequency inverter spot:
- Alignment: Ho jara pele ho netefatsa ho tsamaisana ho nepahetseng ha li-workpieces, ho hokahanya libaka tsa welding ka nepo.
- Ikopanye: Preload e theha kamano e haufi-ufi lipakeng tsa li-electrode le li-workpieces, ho ntlafatsa phetiso ea mocheso le conductivity ea motlakase nakong ea ts'ebetso ea welding.
- Botsitso: Ka ho sebelisa preload, li-workpiece li ts'oaroa ka mokhoa o sireletsehileng, li fokotsa ho sisinyeha kapa ho se tsamaisane hantle nakong ea ts'ebetso ea welding.
- Thibelo ea likheo tsa moea: Ho jara esale pele ho thusa ho tlosa likheo tsa moea kapa litšila tse holim'a metsi lipakeng tsa li-electrode le li-workpieces, ho khothaletsa fusion e sebetsang le ho fokotsa kotsi ea bofokoli lenonyeletsong la weld.
- Lintlha tse Amang Preload: Boholo ba preload ka har'a mochini oa welding oa frequency inverter spot welding bo ka susumetsoa ke lintlha tse fapaneng, ho kenyelletsa:
- Lisebelisoa le botenya ba mosebetsi: Lisebelisoa le botenya bo fapaneng bo hloka maemo a fapaneng a ho jara esale pele ho fihlela tumellano le khokahano e nepahetseng.
- Moralo oa elektrode: Sebopeho, boholo, le thepa ea li-electrode li ka ama kabo le katleho ea ho jara pele.
- Litlhoko tsa ts'ebetso ea welding: Litlhoko tse khethehileng tsa ts'ebetso ea welding, joalo ka moralo o kopaneng kapa thepa ea thepa, li ka laela boemo bo loketseng ba ho jara pele.
- Kopo ea Pele le Taolo: Ho roala esale pele hangata ho sebelisoa ho sebelisoa lisebelisoa tsa pneumatic kapa hydraulic ka har'a mechini ea welding ea maqhubu a mahareng. Litsamaiso tsena li lumella taolo e nepahetseng le ho lokisoa ha matla a ho laela pele ho ipapisitse le litlhoko tse ikhethang tsa welding le litšobotsi tsa workpiece.
