Cov theem twg hauv kev tsim cov hlab ntsha siab tshaj plaws yog qhov ua yuam kev?

1. Vuam theem

Kev faib ua feem ntau ntawm phau ntawv vuam: Kev tuav vuam ua rau cov vuam tsis zoo, nrog cov nqi rov ua haujlwm nce mus txog 5% -8%.

Tsis yooj yim hauv kev tswj cov txheej txheem tsis: Kev hloov pauv hauv qhov tsis xws li tam sim no thiab qhov hluav taws xob yooj yim ua rau muaj qhov tsis xws li porosity thiab slag inclusions.

Kev cuam tshuam ntawm thermal deformation: tuab phaj vuam yog qhov ua rau shrinkage deformation, xav tau kev ntxhov siab los ntawm kev kho cua sov.

2. Cov txheej txheem txiav

Dimensional yuam kev tswj: ntsuas tsuas yog kab pheeb ces kaum tau yooj yim ua rau parallelogram-puab lub cev daim hlau, ua rau weld misalignment.

Kev siv cov khoom siv tsawg: Cov txheej txheem txiav ib txwm yooj yim tsim cov khoom pov tseg, xav tau lub khoos phis tawj - pab npaj cov khoom.

Kev vam khom siab ntawm cov khoom siv: Yog tsis muaj lub tshuab leveling, uncoiling thiab txiav yuam kev tuaj yeem ncav cuag 3 hli.

3. Kev tsim theem

Nplaim txiav deformation: Shrinkage ntawm lub tog raj kheej seem xaus ua rau kev sib dhos nyuaj thiab txo lub taub hau taub.

Kev them nyiaj pwm tsis txaus: Tsis xav txog cov khoom siv springback ua rau qhov kawg qhov ntev tshaj qhov kam rau ua.

Instability deformation: Qhov qhib loj ua rau lub plhaub tsis muaj zog, xav tau kev txhawb nqa ib ntus.

4. Cov txheej txheem tshuaj xyuas

Tsis yog-Kev kuaj qhov muag tsis pom kev puas tsuaj: Cov kab nrib pleb me me tuaj yeem tsis pom, yuav tsum tau siv ntau txoj hauv kev sim.

Kev Ntsuam Xyuas Kev Ruaj Ntseg: Kev ntsuas siab dhau tuaj yeem ua rau muaj kev cuam tshuam tsis zoo, yuav tsum muaj kev tswj hwm nruj ntawm qhov nce siab.

Kev Tiv Thaiv Tseem Ceeb

1. Vuam: Siv nqaim- qhov sib txawv submerged arc vuam kom txo cov vuam deposition, ua ke nrog lub laser nrhiav qhov system.

2. Blanking: Ib txhij ntsuas kab pheeb ces kaum thiab sab ntev, siv lub tshuab leveling.

3. Kev sib sau: Siv symmetrical txiav, tso cai rau shrinkage them nyiaj.

4. Kev tshuaj xyuas: Siv ib qho "peb-kev tshuaj ntsuam xyuas" (kev tshuaj xyuas tus kheej- kev tshuaj xyuas, kev tshuaj ntsuam xyuas, thiab kev tshuaj xyuas tshwj xeeb).
