1. Njikọ mbugharị DC (ya bụ usoro njikọ mbugharị):

Usoro njikọ na-aga n'ihu na-ezo aka na usoro wiring eji atụ ihe nhụsianya dielectric na ule sekit Xilin.Ihe nhụsianya dielectric tụrụ site na ụzọ njikọ na-aga n'ihu dị ntakịrị, na ihe ọnwụ dielectric tụrụ site na ụzọ njikọ azụ dị ukwuu.E jiri ya tụnyere usoro njikọ azụ, usoro njikọ na-aga n'ihu nwere ike ibelata mmetụta nke mgbochi elu antihalo oyi akwa na uru ule ọnwụ dielectric.

2. Njikọ azụ DC (ya bụ usoro njikọ azụ):

Na-ezo aka na usoro njikọ sekit n'oge ịgbado ọkụ.Na tungsten arc welding, DC reverse njikọ nwere mmetụta nke iwepu oxide film, nke a na-akpọ "cathode fragmentation" ma ọ bụ "cathode atomization".

Mmetụta nke iwepụ ihe nkiri oxide dịkwa na ntụgharị polarity ọkara nke ịgbado ọkụ AC.Ọ bụ ihe dị mkpa na ịgbado ọkụ nke ọma aluminum, magnesium na ha alloys.

Ụkpụrụ nke njikọ azụ DC:
Mgbe DC na-atụgharị, ihe nkiri oxide n'elu nke workpiece nwere ike wepụ n'okpuru omume nke arc iji nweta weld na-egbuke egbuke, mara mma na nke ọma.

Nke a bụ n'ihi na ígwè oxides nwere obere ọrụ na-arụ ọrụ ma na-ebupụ electrons ngwa ngwa, ya mere ntụpọ cathode dị mfe ịmepụta na fim oxide ma mepụta arcs.The cathode tụrụ nwere ihe onwunwe nke na-akpaghị aka na-achọ metal oxides.

Ngwunye ike nke ntụpọ cathode dị oke elu, ọ na-akụkwa ya site na ion dị mma na nnukwu uka, nke na-agbaji ihe nkiri oxide.

Otú ọ dị, mmetụta okpomọkụ nke DC reverse njikọ na-emebi ịgbado ọkụ, n'ihi na anode nke tungsten argon arc ịgbado ọkụ na-ekpo ọkụ karịa cathode.Mgbe a na-atụgharị polarity, electrons na-atụba tungsten electrode ma hapụ nnukwu okpomọkụ, nke nwere ike ime ka ọ dịkwuo ọkụ ma gbazee tungsten electrode.N'oge a, ọ bụrụ na a ga-agafe ugbu a ịgbado ọkụ nke 125A, mkpara tungsten nke nwere dayameta nke ihe dịka 6mm iji gbochie tungsten electrode ịgbaze.

N'otu oge ahụ, n'ihi na enweghi ike dị ukwuu a na-ewepụta na weldment, omimi ntinye weld na-emighị emi na mbara, arụpụtaghị ihe dị ala, na naanị ihe dị ka 3mm nnukwu efere aluminum nwere ike welded.Ya mere, DC reverse njikọ na-adịkarịghị eji tungsten arc ịgbado ọkụ ma e wezụga maka ịgbado ọkụ aluminum na magnesium mkpa efere.
