Dab tsi yog qhov tsis xws luag yuav tshwm sim hauv kev tsim cov hlab ntsha siab?

1. Welding Defects (Qhov tshwm sim ntau tshaj plaws, feem ntau muaj qhov tsis xws luag)
Vuam yog ib qho ntawm cov txheej txheem tseem ceeb tshaj plaws hauv kev tsim cov hlab ntsha siab, ua rau muaj kev cuam tshuam rau tib neeg kev ua yuam kev, cov txheej txheem tsis zoo, thiab ib puag ncig, ua rau nws muaj feem cuam tshuam rau qhov tsis xws luag. Cov teeb meem muaj xws li porosity, slag inclusions, incomplete penetration, tsis muaj fusion, undercut, thiab tsis yog -raws li weld qhov ntev. Vuam tawg yog hom txaus ntshai tshaj plaws. Cov teeb meem no ncaj qha txo cov vuam lub zog thiab kev ntseeg siab, ua rau muaj kev pheej hmoo loj ntawm kev tawg thiab tawg hauv cov hlab ntsha siab tom qab.

2. Cov khoom tsis zoo
Cov ntaub ntawv raw lawv tus kheej, los yog qhia thaum lub sij hawm kev tshuaj ntsuam xyuas, nws muaj feem cuam tshuam los yog qhia txog qhov tsis xws luag xws li cov kab nrib pleb, kev sib txuas, porosity, delamination, thiab nto khawb thiab qhov. Yog tias cov ntaub ntawv tsis tsim nyog raug xaiv lossis kev tshuaj xyuas tuaj tsis nruj, cov teeb meem no yuav raug coj ncaj qha mus rau hauv cov txheej txheem tsim khoom, cuam tshuam rau tag nrho lub zog thiab siab tsis kam ntawm lub nkoj.

3. Kev kho cua sov tsis zoo
Kev kho cua sov yog txheej txheem tseem ceeb rau kev tshem tawm qhov seem ntawm qhov vuam kev nyuaj siab thiab kho cov khoom toughness. Cov tsis xws luag yog yooj yim generated vim tsis raug tswj ntawm cov txheej txheem tsis. Cov teeb meem tshwm sim muaj xws li tsis txaus annealing, uas ua rau cov kev ntxhov siab tsis txaus thiab cov khoom tsis txaus, nrog rau overheating thiab cracking, ua rau muaj kev pheej hmoo ntawm kev tawg ntawm lub nkoj.

4. Geometric Dimensional Deviations: Cov kev tsis zoo no feem ntau tshwm sim thaum lub sijhawm tsim thiab ua tiav. Feem ntau cov piv txwv muaj xws li ellipticity ntau dhau ntawm lub tog raj kheej, ntau qhov tsis zoo ntawm cov pob qij txha, qhov tsis sib xws ntawm lub kaus mom kawg, thiab ntau qhov ntsug ntawm cov hlab ntsha. Cov ellipticity ntau dhau ntawm lub tog raj kheej yog ib qho teeb meem tshwj xeeb, ua rau muaj teeb meem kev teeb tsa lossis kev ntxhov siab hauv cheeb tsam, yog li cuam tshuam rau kev nyab xeeb ntawm cov qauv.

5. Cold Working Defects: Cov txheej txheem ua haujlwm txias (xws li phaj dov thiab straightening) yog qhov ua rau muaj kev ntxhov siab thiab kev sib hloov. Txawm hais tias qhov seem sab hauv kev ntxhov siab tsis ncaj qha ua rau tawg, nws tuaj yeem ua rau qaug zog tawg thiab kev ntxhov siab corrosion tawg hauv cov hlab ntsha tom qab.
