(3) Kev sib txuas ntawm qhov nrhiav kom pom

Welding node nrhiav tau

Kev ntsuas qhov chaw: kev sib txuas welds ntawm txhua kab thiab kab teeb, truss node welds, kev sib txuas welds ntawm vaj huam sib luag txhawb nqa thiab lub cev loj, kev sib txuas welds ntawm cov ntaiv thiab lub cev loj;

Kev tshuaj xyuas qhov tshwm sim: cov teeb meem xws li weld qhov siab tshaj, undercutting, vuam tsis tiav, porosity, slag suav nrog, thiab lwm yam;

Kev kuaj tsis muaj kev puas tsuaj: Ultrasonic kuaj (UT) yog siv los kuaj xyuas qhov tsis xws luag hauv cov welds tseem ceeb hauv kev ntxhov siab.

 

High zog bolt node nrhiav kom tau

Cov khoom kuaj: truss node bolts, crossbeam kho bolts, kem splicing flange bolts, vaj huam sib luag txhawb bolts;

Kev tshuaj xyuas qhov tshwm sim: Tshawb xyuas cov ntsia liaj qhov rooj, xov puas, thiab cov gaskets uas ploj lawm, txheeb xyuas cov ntsia hlau tawg, xov slippage, thiab flange nto nruj

Tshawb xyuas cov kev qhia tshwj xeeb, qhov ntau, thiab qhov tob tob ntawm qhov nthuav dav bolts / tshuaj thauj tog rau nkoj bolts, thiab txheeb xyuas lawv qhov sib xws nrog tus nqi tsim; Txheeb xyuas qhov rub- tawm ntawm cov thauj tog rau nkoj bolts; Txheeb xyuas qhov kev pheej hmoo ntawm cov ntawv tshaj tawm kev tshem tawm ntawm phab ntsa / ru tsev los ntawm xoob thauj tog rau nkoj bolts.

 

(4) Advertising vaj huam sib luag thiab teeb pom kev zoo tshuaj xyuas

Txawm hais tias cov ntawv tshaj tawm thiab cov chaw teeb pom kev zoo tsis tuaj yeem nqa lub ntsiab thauj khoom, lawv ncaj qha cuam tshuam rau pej xeem kev nyab xeeb thiab yog cov ntsiab lus ntxiv uas yuav tsum tau kuaj tshwj xeeb
