Muaj peb yam tsis zoo ntawm LED welds: 2018-01-25: 333 Cov nyhuv stele sib txawv vim qhov sib txawv ntawm tag nrho cov muab tshuaj txhuam, vim cov nyhuv thermal expansion thiab contraction thaum lub sij hawm vuam txheej txheem. Lub zog tensile uas tsim los ntawm cov pob qij txha ntau dua yog qhov loj, thiab cov khoom siv nrog cov ntim tsawg dua yog qhov tensile tsawg. Lub tensile quab yuam tsim los ntawm qhov loj ntawm cov vuam pob qij txha yog txaus los rub cov welded pob qij txha nrog tsawg ntim, los yog qhov tshwm sim ntawm de -welding, los yog vim lub txias ceev ntawm lub txias ceev, los yog vim hais tias ntawm lub cua txias ceev, Poob siab tsis taus, cov pob qij txha kub welded uas tshwm sim tsis tau txias, lub zog contraction tsis tsim los yog me me, thiab lub txias solder tau pib ntsws, uas ua rau ib tug loj contraction quab yuam, uas ua rau rub lub kub welding pob qij txha. Nws yog hu ua monument effect. Raws li pom nyob rau hauv daim duab: yog vim li cas rau lub monument nyhuv: 1. Qhov loj ntawm lub ncoo PAD tsis sib npaug. 2. Lub degree ntawm smoothness ntawm welded nto yog txawv. 3. Cov cua kub kev taw qhia ntawm vuam qhov chaw / Ntsuas. 4. Tus nqi ntawm tinnum muab tshuaj yog tsis sib npaug. 5. Tag nrho cov txheej txheem ntawm cov khoom siv hluav taws xob (IR yog welded). 6. Cua ceev thiab kev co thaum lub sij hawm rov qab vuam txheej txheem. 7. Qhov ceev ntawm cov cua sov ntawm cov welded qhov chaw yog tsis sib xws. Cov nyhuv txhais lus yog Vim muaj ntau qhov sib txawv ntawm ob lub tin pastes, lub melting tinnut yuav ua rau cov khoom lifted txawv. Nyob rau hauv qhov kev txiav txim ntawm lub ntiajteb txawj nqus, cov ntaub ntawv yuav txhais. . Raws li pom nyob rau hauv daim duab: Ob lub tin pastes nrog tib tus nqi ntawm cov nyhuv tib yam yuav raug tsa tom qab cua sov, thiab tom qab ntawd cov khoom yuav cia li tig mus rau pem hauv ntej thiab nraub qaum thiab sab laug thiab txoj hauj lwm kom nws nyob rau tib qhov siab. .
