Kusondeze ku-plasma arc welding

Isingeniso

I-Plasma arc welding ibhekisela endleleni ye-fusion welding esebenzisa i-high-energy-density plasma arc beam njengomthombo wokushisa wokushisela. I-Plasma arc welding inezici zamandla agxilile, ukukhiqiza okuphezulu, isivinini sokushisela okusheshayo, ukucindezeleka okuphansi nokuguqulwa, i-arc ezinzile, futhi ifanele ukushisela amapuleti amancane nezinto zebhokisi. Ifaneleka ngokukhethekile ukushisela izinto ezihlukahlukene zensimbi eziphikisayo, ezine-oxidized, nezizwela ukushisa (njenge-tungsten, i-molybdenum, ithusi, i-nickel, i-titanium, njll.).

Igesi ishiswa yi-arc futhi ihlukaniswe. Uma idlula ku-nozzle epholile ngamanzi ngesivinini esikhulu, iyacindezelwa, ikhulise ukuminyana kwamandla kanye ne-dissociation degree ukuze yakhe i-plasma arc. Ukuzinza kwayo, ukukhiqizwa kokushisa, kanye nezinga lokushisa kuphakeme kunama-arcs ajwayelekile, ngakho-ke inokungena okukhulu nesivinini sokushisela. Igesi eyenza i-plasma arc kanye negesi evikelayo ezungezile ngokuvamile isebenzisa i-argon ehlanzekile. Ngokusho kwezakhiwo zezinto zokusebenza ezihlukahlukene, i-helium, i-nitrogen, i-argon, noma ingxube yalokhu kokubili kuyasetshenziswa.

Isimiso

Ukusika i-Plasma arc kuyindlela evame ukusetshenziswa yokusika izinto zensimbi nezingezona ezensimbi. Isebenzisa i-high-speed, izinga lokushisa eliphezulu kanye ne-high-energy plasma airflow ukushisa nokuncibilikisa okokusebenza okuzosikwa, futhi isebenzisa ukugeleza komoya kwangaphakathi noma kwangaphandle kwesivinini esikhulu noma ukugeleza kwamanzi ukusunduza into encibilikisiwe kuze kube yilapho i-plasma airflow beam ingena ngaphakathi. emuva ukuze wenze ukusikeka.

Imishini yokushisela i-Xinfa inezici zekhwalithi ephezulu nenani eliphansi. Ukuze uthole imininingwane, sicela uvakashele:Abakhiqizi Bezinto Zokushisela Nezokusika - Imboni Yokushisela Nokusika YaseChina Nabahlinzeki (xinfatools.com)

Izici

1. I-Micro-beam plasma arc welding ingashisela ucwecwe namapuleti amancane.

2. Inomphumela we-pinhole futhi ingafinyelela ukushisela okunohlangothi olulodwa kanye nokwakheka kwamahhala okunezinhlangothi ezimbili.

3. I-plasma arc inomthamo omkhulu wamandla, izinga lokushisa eliphezulu lekholomu ye-arc, nekhono elinamandla lokungena. Ingakwazi ukufeza insimbi engu-10-12mm obukhulu ngaphandle kwe-beveling. Ingakwazi ukushisela ezinhlangothini zombili ngesikhathi esisodwa, ngesivinini sokushisela esisheshayo, ukukhiqiza okuphezulu, nokuwohloka kokucindezeleka okuncane.

4. Imishini iyinkimbinkimbi, isebenzisa igesi ephezulu, izidingo eziqinile kwigebe phakathi komhlangano kanye nokuhlanzeka kwe-workpiece, futhi ifaneleka kuphela ukushisela kwangaphakathi.

Ukunikezwa kwamandla kagesi

Lapho kusetshenziswa ukushiselwa kwe-arc ye-plasma, izinsiza zamandla eziqondile zamanje kanye ne-droop ngokuvamile zisetshenziswa. Ngenxa yezici zokusebenza eziyingqayizivele ezitholwe elungiselelweni lethoshi elikhethekile kanye ne-plasma ehlukene kanye nokugeleza kwegesi evikelayo, ukunikezwa kwamandla okujwayelekile kwe-TIG kungenziwa kwengezwe ku-console ye-plasma, futhi uhlelo lwe-plasma olwakhiwe ngokukhethekile lungasetshenziswa. Akulula ukuzinzisa i-arc ye-plasma uma usebenzisa i-sine wave AC. Lapho ibanga eliphakathi kwe-electrode kanye ne-workpiece lide futhi i-plasma icindezelwa, i-arc ye-plasma kunzima ukusebenza, futhi emjikelezweni wesigamu esihle, i-electrode eshisa ngokweqile izokwenza ithiphu eliqhutshwayo libe yindilinga, elizophazamisa ukuzinza kwe-electrode. i-arc.

Ukunikezwa kwamandla okushintshashintsha kwe-DC okuzinikele kungasetshenziswa. Ngokulungisa ibhalansi ye-waveform ukuze kuncishiswe ubude be-electrode positive pole, i-electrode ipholiswe ngokuphelele ukuze igcine umumo wethiphu ekhonjiwe futhi yakhe i-arc ezinzile.
