I-Hikelokama-miniature butt-weld fittingsasetshenziswa kakhulu endaweni ye-ultra-purity embonini ye-semiconductor futhi afanele ukuxhunywa kwamapayipi emidiya ehlanzekile kakhulu. Kuyisilinganisi esishiselwe. Izinhlobo zayo eziyinhloko zesakhiwo zihlanganisainyunyana eqondile, indololwane, teefuthiisiphambano. Inezici zeumthamo omncane, usayizi onembile wokuphela kwe-welding, ubuso obuyisicaba, umphetho obukhali ngaphandle kwe-burr, i-tube wall iyunifomu, welding olunembile futhi ngcono repeatability of Welding.
Imodi yokushisela
Kunconywa ukusebenzisa i-tungsten arc welding (GTA), ezokwenziwa ngokuya ngezinqubo zokushisela kanye nezidingo ku-SEMI F78-0304 standard, futhi ihlolwe ngokuya nge-SEMI F81-1103 ejwayelekile. Ukushiselwa kokufakwa kwe-butt-weld encane kuzokwenziwa ngemishini yokushisela ezenzakalelayo. Ukuphathwa kwe-welding okuhlelekile nokujwayelekile kungaqinisekisa izinga lokushisela lemikhiqizo.
Umshini wokushisela we-argon arc othomathikhi
Izici zesakhiwo
Ubulukhuni bokupholisha obujwayelekile besiteshi sangaphakathi sokufakwa kwe-butt-weld encane ngu-10μin. (0.25μm) Ra, electropolishing kufika ku-5μin. (0.13μm), ikhoneni lesiteshi sokugeleza ekufakweni kwendololwane ukuxhumana okuyisiyingi ngaphandle kwendawo yokuhlukanisa, elungele ukushintshwa okubushelelezi kokuphakathi.
Izidingo zezinto ezibonakalayo
I-316L, 316L VAR ne-316L VIM-VAR insimbi engagqwali isetshenziswa njengokucubungula izinto ezingavuthiwe, ezihlangabezana nezidingo ze-SEMI F20-0704 ejwayelekile. Ukufakwa kwalezi zinto ezintathu kungamelana nezinga lokushisa elisuka ku -198 ℃ liye ku-454 ℃. Ngokusho kwe-ASME B31.3, ingcindezi yokusebenza ephezulu ingafinyelela ku-8500 psig.
Amafomu okuxhumana
I-miniature butt-weld fitting isetshenziselwa kakhulu uxhumano lwe-butt welding ngochungechunge lwe-ultra-purityamantongomanefuthiizindlala. Ifanele ukuhlelwa kwesistimu ngesikhala esihlangene. Isibalo sibonisa umdwebo wokushisela we-miniature butt-weld tee kanye nezingxenye. Ngokwezinhlelo ezihlukene zesakhiwo, indololwane encane engu-90° kanye nesiphambano nayo ingakhethwa ukuze ishiselwe.
Ukuze uthole imininingwane eyengeziwe yoku-oda, sicela ubheke okukhethiweamakhathalogikuIwebhusayithi esemthethweni ye-Hikelok. Uma unanoma yimiphi imibuzo yokukhetha, sicela uxhumane nabasebenzi abathengisa ku-inthanethi be-Hikelok bamahora angu-24.
