Cov pwm muaj qhov tseem ceeb siv hauv kev lag luam niaj hnub no. Nws cov khoom ua tau zoo kuj txiav txim siab cov khoom ua haujlwm zoo ntawm cov khoom. Txawm li cas los xij, nyob rau hauv tag nrho cov txheej txheem pwm daim ntawv thov, teeb meem xws li vau, deformation, puas tsuaj, thiab txawm tias pob txha tawg feem ntau tshwm sim. Txhawm rau kom tsis txhob ncua ntau lawm, lub pwm yuav tsum tau kho. Nyob rau theem no, feem ntau txoj hauv kev siv los kho cov pwm yog cov no ob: fiber ntau kho qhov muag hlau vuam tshuab thev naus laus zis kho tshuab, argon arc vuam tshuab kho. Zh
Cov khoom siv hlau tsis muaj tshuab raj hlau
1. Kev kho cov cuab yeej ntawm cov tshuab hluav taws xob fiber ntau laser vuam tshuab: lub tshuab laser hlau vuam yog lub tshuab ua haujlwm laser yog ua tiav los ntawm kev siv cov laser ua los ntawm kev tsom cov ntsiab lus ntawm lub zog loj txuas xim xim photon ntws raws li pyrogen. Hom vuam thev naus laus zis feem ntau suav nrog kev txuas hlau txuas cov tshuab hlau txuas thiab cov tshuab hluav taws xob tsim cov tshuab laser hlau vuam tshuab. Qhov zoo ntawm cov hlau laser vuam tshuab yog tias nws tsis tas yuav tsum tau nqa tawm hauv qhov chaw nqus tsev. Qhov tsis zoo yog tias nws tsis muaj zog li laser welding. Thaum lub sijhawm laser vuam, qhov kev hloov kho lub zog hluav taws xob tuaj yeem nqa tawm, yog li laser vuam ntawm qhov siab ua haujlwm cov khoom lag luam tuaj yeem tswj tau. Nws tuaj yeem siv rau ntau cov ntaub ntawv hlau, tshwj xeeb tshaj yog laser vuam uas tuaj yeem daws qee cov ntaub ntawv hlau tsis yooj yim thiab cov khoom siv hlau sib txawv. Nyob rau theem no, nws tau siv dav siv los kho pwm.
2. Kho kho ntawm argon arc vuam tshuab: Qhov pib vuam pab los ntawm kev pub mis tas mus li ntawm cov electrode thiab cov hlau yog siv los ua cov pa, thiab cov pa cua hlau arc txau los ntawm cov tsau nozzle yog siv los nqa tawm cov hlau ua haujlwm. Nyob rau theem no, argon arc vuam tshuab yog hom kev sib koom, uas tuaj yeem siv rau feem ntau cov khoom siv hlau, nrog rau cov pa roj carbon steel thiab cov hlau tsis huv. Fused kawg inert gas shielded vuam yog tsuas yog siv rau stainless hlau daim hlau, aluminium, magnesium, tooj liab, titanium, zirconium thiab npib tsib xee alloys. Xav txog tus nqi pheej yig, feem ntau siv rau pwm kho vuam, tab sis tag nrho cov cheeb tsam ntawm kev cuam tshuam los ntawm kev cuam tshuam los ntawm laser vuam yog qhov loj thiab lub vuam kis loj thiab lwm yam tsis xws luag, nyob rau theem no nyob rau hauv lub siab-precision pwm kho qhov chaw tau maj mam hloov los ntawm cov tshuab ua npuas hlau ua tshuab.
