Eli nqaku lijongana nombuzo wokuba ngaba i-medium frequency inverter spot welding machine outputs pulsed current ngqo (DC).Ukuqonda ubunjani bemveliso yombane kubalulekile ekuhloleni ukufaneleka komatshini we-welding kwizicelo ezithile kunye nokuphucula inkqubo ye-welding.
- Umgaqo-siseko wokuSebenza: Umatshini we-welding we-medium frequency inverter spot welding usebenza kumgaqo wokuguqula i-alternating current (AC) igalelo kwisiphumo esithe ngqo sangoku (DC) ngokusebenzisa i-inverter circuit.Isekethe ye-inverter ibandakanya izinto ezinje ngokuhlaziya kunye nezihluzi ezilawula i-wave waveform.
- I-Pulsed Operation: Kwiimeko ezininzi, ii-medium frequency inverter spot welding machine zenzelwe ukuhambisa i-pulsed current ngexesha lenkqubo ye-welding.I-Pulsed current ibhekisa kwi-waveform apho ikhoyo ngoku ngamaxesha athile itshintshana phakathi kwamanqanaba aphezulu nasezantsi, idala i-pulsating effect.Esi senzo se-pulsing sinokubonelela ngeenzuzo ezahlukeneyo, kubandakanywa igalelo lobushushu elincitshisiweyo, ulawulo oluphuculweyo lwenkqubo ye-welding, kunye nokunciphisa ukuphazamiseka.
- I-Direct Current (DC) Component: Ngelixa i-medium frequency inverter spot welding machine ihambisa ngokuyintloko i-pulsed current, ikwaqulethe icandelo elithe ngqo (DC) langoku.Icandelo le-DC liqinisekisa i-arc ye-welding ezinzileyo kwaye inegalelo ekusebenzeni kwe-welding jikelele.Ubukho becandelo le-DC bunceda ukugcina ukuzinza kwe-arc, kukhuthaza ixesha elide le-electrode, kwaye kuququzelele ukungena kwe-weld okungaguqukiyo.
- Ulawulo lweziphumo: Umatshini we-welding we-inverter ophakathi nendawo uvumela ukulungelelanisa i-pulse frequency, ubude be-pulse, kunye ne-amplitude yangoku, ukubonelela ngokulawula inkqubo ye-welding.Ezi parameters ezihlengahlengiswayo zenza ukuba abaqhubi baphucule iimeko ze-welding ngokusekelwe kwizinto eziphathekayo, ukucwangciswa ngokubambisana, kunye neempawu ezifunwayo ze-weld.
Umatshini wokuwelda indawo yokutshintsha amaza aphakathi udla ngokukhupha ipulsed current ngecandelo elithe ngqo langoku (DC).I-pulsed current inika izibonelelo ngokubhekiselele kulawulo lwegalelo lobushushu kunye nomgangatho we-weld, ngelixa icandelo le-DC liqinisekisa iimpawu ze-arc ezizinzileyo.Ngokubonelela ngokuguquguqukayo ekulungiseni iiparamitha ze-pulse, umatshini we-welding wenza ukuba abaqhubi bafezekise ulawulo oluchanekileyo malunga nenkqubo ye-welding.Ukuqonda iimpawu zemveliso yomatshini kubalulekile ekukhetheni iiparamitha ezifanelekileyo ze-welding kunye nokwandisa umgangatho we-welding kunye nokusebenza kakuhle.
