Feem ntau siv CO2 vuam hlau diameters (hli): 0.6, 0.8, 1.0, 1.2, 1.4, 1.6, 2.0, 2.4, 2.5, 3.0, 3.2, 4.0, 5.0, 6.0, thiab lwm yam. voltage thiab lwm yam kev ntsuas, thiab tseem qhia sib txawv kev hloov fusion hloov thiab arc yeeb yam. Txoj kab uas hla ntawm vuam hlau peb siv feem ntau yog muab suav sau ua peb hom:
Filament
Cov xaim nyias yog cov hlau xaim nrog lub taub me dua 1.2mm. Feem ntau, vuam ua nyob rau hauv daim ntawv ntawm kev hloov mus luv luv. Nws yog yus muaj los ntawm tsis tshua muaj arc voltage thiab me me tam sim no, thiab haum rau vuam nyias daim hlau thiab rau txhua txoj hauj lwm vuam. Thaum vuam vias nyias cov paib, cov khoom tsim tau loj thiab deformation yog me me. Ntxiv mus, nws yooj yim los tus tswv hauv kev ua haujlwm thiab tsis xav tau welder thev naus laus zis loj. Tsis tas li ntawd xwb, vim muaj qhov tsis muaj vuam me me, lub teeb hluav taws xob, hluav taws xob tiv tshav kub thiab vuam pa hluav taws xob thaum lub sijhawm vuam cov txheej txheem kuj tseem me me, yog li nws tau siv dav hauv ntau lawm. Qhov txoj kab uas hla ntawm vuam hlau siv cov hluav taws xob hloov luv vuam yog li 1.6mm. Piv txwv li, yog hais tias lub vuam hlau loj dua 1.6 hli yog luv luv vuam voos, qhov kev sib kis loj heev, thiab nws tsis tshua muaj siv nyob rau hauv ntau lawm.
Nruab nrab hlau
Cov kab nruab nrab yog xaim xaim hlau nrog lub taub ntawm 1.6 ~ 2.5mm. Feem ntau, cov tee tawg yog welded rau hauv daim ntawv ntawm cov zoo hloov me me. Nws yog tsiag ntawv los ntawm qhov loj dua tam sim no thiab ntau dua arc voltage, thiab cov tee dej poob rau hauv pas dej molten hauv daim ntawv ntawm lub caij nplooj zeeg dawb hauv qhov loj me. Thaum cov nplais hluav taws xob tau hloov mus, arc nkag mus rau lub zog loj, thiab tus ntoo nkag mus yog qhov loj, uas tsim nyog rau vuam nruab nrab thiab tuab daim hlau.
Tuab hlau
Tuab cov hlau yog cov hlau tsis muaj vuam siv nrog txoj kab uas hla ntawm 2.5 txog 6.0 hli, feem ntau yog nqus dej arc vuam siv. Nws yog yus muaj los ntawm loj tam sim no thiab tsawg arc voltage. Qhov kawg ntawm vuam hlau thiab arc dive rau hauv lub qhov taub ntawm lub pas dej molten, thiab cov roj hmab hloov chaw mus rau qhov chaw da dej sib tsoo los ntawm qhov chaw arc ntawm kev kub ceev nrog cov nplua me me dua li ntawm txoj kab uas hla ntawm lub vuam hlau. Tus txheej txheem welding yog tus, tsis muaj lub voj voog luv, thiab tus spatter yog me me. Nws yog ib txoj hauv kev ntawm kev kub ceev vuam.
