Yintoni iXesha laPhambi kokuCofa koomatshini bokuWelding abaPhakathi beFrequency?

Oomatshini bokuwelda bamabala aphakathi basetyenziswa kakhulu kumashishini ahlukeneyo ngokusebenza kwabo kunye nokuchaneka ekudibaniseni isinyithi. Enye ipharamitha ebalulekileyo kwinkqubo ye-welding yendawo lixesha lokucinezela kwangaphambili, elidlala indima ebalulekileyo ekuqinisekiseni umgangatho kunye nokuqina kwamalungu adityanisiweyo.

Ixesha lokucinezela kwangaphambili, elikwabizwa ngokuba lixesha lokucudisa okanye ukubamba ixesha, libhekisa kwixesha apho i-electrode ye-welding ifaka uxinzelelo kwizinto zokusebenza ngamandla athile ngaphambi kokuba kusetyenziswe umsinga welding. Esi sigaba siyimfuneko ngenxa yezizathu ezininzi:

1. Ulungelelwaniso kunye noQhagamshelwano:Ngexesha lokucofa kwangaphambili, ii-electrodes zenza uxinzelelo kwii-workpieces, ziqinisekisa ukulungelelaniswa okufanelekileyo kunye noqhagamshelwano oluhambelanayo phakathi kweendawo zetsimbi. Oku kunciphisa ukubakho kwezithuba zomoya okanye uqhagamshelwano olungalinganiyo, nto leyo enokukhokelela kumgangatho ombi weld.
2. Ukucoca uMphezulu:Ukufaka uxinzelelo kunceda ukukhupha izinto ezingcolileyo, i-oxides, kunye nezitenxo zomhlaba ukusuka kwindawo ye-welding. Oku kuqinisekisa indawo ecocekileyo kunye ne-conductive ukwenzela ukuba i-welding current idlule, ibangele i-weld enamandla kwaye ethembekileyo.
3. Ukuthambisa izinto:Ngokuxhomekeke kwiintsimbi ezifakwe kwi-welding, ixesha lokucofa kwangaphambili linokuba negalelo ekuthobeni kwezinto eziphathekayo kwindawo ye-welding. Oku kunokwenza kube lula ukuhamba kwezinto ezilandelayo ngexesha lenkqubo ye-welding, ekhokelela ekudibaneni okungcono kunye nokudibanisa okuqinileyo.
4. Ukusasazwa koxinzelelo:Ukucofa kwangaphambili ngokufanelekileyo kuvumela uxinzelelo ukuba lusasazeke ngokulinganayo kuwo wonke ama-workpieces. Oku kubaluleke kakhulu xa udibanisa izinto ezinobunzima obahlukeneyo, njengoko kunceda ukuthintela ukugqwesa okanye ukungqubana kwamacandelo.

Elona xesha lifanelekileyo lokucinezela kwangaphambili linokwahluka ngokusekelwe kwizinto ezifana nohlobo lwemathiriyeli, ubukhulu, amandla e-electrode, kunye nesicelo se-welding ethile. Lulungelelwano phakathi kokuvumela ixesha elaneleyo lokuba ezi zibonelelo zikhankanywe ngasentla zenzeke ngaphandle kokwandisa ngokungeyomfuneko umjikelo wokuwelda.

Ukuqukumbela, ixesha lokucinezela kwangaphambili kumatshini wokuwelda amabala aphakathi liyiparameter ebalulekileyo echaphazela kakhulu umgangatho kunye nokuthembeka kwamalungu adityanisiweyo. Ngokuqinisekisa ukulungelelaniswa okufanelekileyo, ukungcola, ukuthambisa izinto eziphathekayo, kunye nokusabalalisa uxinzelelo, esi sigaba sibeka isiseko senkqubo ye-welding eyimpumelelo. Abavelisi kunye nabaqhubi kufuneka baqikelele ngononophelo kwaye bahlengahlengise ixesha lokucofa kwangaphambili ukufezekisa iziphumo ezigqwesileyo kwizicelo zabo ze-welding.
