Cov txheej txheem kho twg yog qhov zoo tshaj plaws rau kub khiav thermal shock cracking?

Raws li peb cov kev sib tham yav dhau los ntawm qhov ua tau thiab lub neej tom qab kho qhov kub khiav thermal shock cracking kho, argon arc vuam (argon arc vuam) ua ke nrog kev ntxhov siab tag nrho- kev kho cua sov yog qhov kev kho kom haum tshaj plaws, tshwj xeeb tshaj yog rau cov uas tsis yog - nkag mus rau hauv qhov tob microcracks:

Ua ntej, thaj tsam tawg yog hauv av thiab ntxuav kom tshem tawm cov kab nrib pleb ntxiv, kom tsis txhob muaj kev txhim kho ntxiv ntawm cov seem microcracks.

Txo qhov sib txuam ntawm cov kev ntxhov siab vuam, kho cov pob txha tawg los ntawm txheej nrog vuam hlau ntawm cov khoom siv hluav taws xob kub ntawm cov khoom siv qis qis -tam sim no tsis tshua muaj - cua sov- tawm argon arc vuam.

Tom qab vuam tag nrho cov workpiece yuav tsum muab tso rau hauv lub qhov cub rau kev ntxhov siab-relieving tshav kub kev kho mob ntawm 600-650℃rau 2-3 teev kom tshem tawm cov seem welding kev nyuaj siab tag nrho.

Thaum kawg grind thiab polish lub weld cheeb tsam thiab ua ib tug dye penetrant tshuaj xyuas kom paub tseeb tias tsis muaj microcrack tshiab tau tsim.

Cov txheej txheem no txo ​​qis tom qab kev sib tsoo, yog qhov zoo tagnrho rau qhov kub thiab txias ntawm cov neeg khiav dej num kub, thiab tsuas yog siv tau rau cov kab nrib pleb me me uas tsis nkag mus rau hauv qhov khiav, qhov sib sib zog nqus tawg tsis tsim nyog kho.
