Thaum twg yog qhov tsim nyog dua los siv rauj rauj?
Hammering tsis tuaj yeem tshwm sim hauv lub hauv paus vuam lossis txheej txheej. Vim li cas? Yog tsis yog, thaum twg nws yog txoj cai los siv rauj?
Rauj yuav ua rau lub vuam hlau nthuav dav tom qab, kom lub zog tensile hauv lub vuam yog offset thaum txias. Yog li ntawd, hammering tuaj yeem tswj tau qhov deformation ntawm cov hlau weld, stabilize qhov loj me, tshem tawm cov kev ntxhov siab welding residual, thiab tiv thaiv vuam tawg. Hammering yuav tsum tau ua ntawm txhua qhov vuam kom ua tau zoo. Qhov kev ua tau zoo ntawm hammering txo qis thaum lub thickness ntawm cov vuam nce los yog hammering yog ua tom qab vuam ntau txheej.
Thawj weld yog qhov nyias nyias thiab tsis tuaj yeem tiv taus rauj hnyav, thaum lub hau npog txheej weld yuav ua haujlwm txias thiab tawv los ntawm hammering, thiab tsis muaj peev xwm kho cua sov los ntawm txheej tom ntej ntawm weld. Yog li ntawd, thawj txheej ntawm weld thiab npog txheej weld yuav tsum tsis txhob hammered.
