fusion tsis tiav, feem ntau hu ua "voids" lossis "porosity," hauv cov txiv ntoo vuam tshuab tuaj yeem ua rau muaj kev cuam tshuam rau kev sib txuas zoo thiab kev sib koom ua ke. Kab lus no tshawb txog qhov cuam tshuam tsis zoo ntawm kev ua tsis tiav fusion thiab hais txog qhov tseem ceeb ntawm kev daws qhov teeb meem no kom ntseeg tau tias cov txiv ntoo ruaj khov thiab ruaj khov.
- Compromised Joint Strength: Tsis tiav fusion ua rau tsis muaj zog welds. Qhov tsis muaj fusion ntawm cov txiv ntoo thiab cov khoom siv hauv paus txo cov peev txheej ntawm kev sib koom ua ke, cuam tshuam nws lub zog tag nrho. Qhov no tuaj yeem ua rau ua tsis tiav thaum ntxov raws li cov khoom siv los yog kev vibrations, ua rau muaj kev puas tsuaj rau cov txheej txheem ntawm kev sib dhos.
- Ua kom muaj kev pheej hmoo ntawm cov dej xau: Tsis tiav fusion tsim qhov khoob lossis qhov khoob hauv qhov chaw vuam, uas tuaj yeem ua txoj hauv kev rau cov kua dej los yog roj. Hauv cov ntawv thov uas cov welded txiv ntseej yog ib feem ntawm lub kaw lus kaw, xws li hydraulic lossis pneumatic cov rooj sib txoos, muaj cov voids tuaj yeem cuam tshuam qhov kev ncaj ncees ntawm lub kaw lus, ua rau kom tawg thiab poob ntawm kev ua haujlwm.
- Txo Fatigue Resistance: Welds nrog tsis tiav fusion yog qhov cuam tshuam rau kev qaug zog tsis ua haujlwm. Lub xub ntiag ntawm voids tsim cov ntsiab lus kev ntxhov siab, ua rau muaj qhov tshwm sim ntawm kev tawg thiab kev nthuav tawm thaum lub sij hawm thauj khoom cyclic. Qhov no tuaj yeem txo qhov qaug zog lub neej ntawm cov welded sib koom ua ke, ua rau nws yooj yim rau kev tsis ua hauj lwm tam sim ntawd thiab cuam tshuam tag nrho cov kav ntev ntawm lub rooj sib txoos.
- Impaired Corrosion Resistance: Tsis tiav fusion tuaj yeem tsim cov crevices lossis microgaps uas txhawb nqa cov khoom sib xyaw ntawm cov dej noo, corrosive agents, lossis cov kab mob. Cov khoom daig no tuaj yeem ua kom cov txheej txheem corrosion, ua rau thaj tsam corrosion thiab tsis muaj zog ntawm kev sib koom ua ke thaum lub sijhawm. Nyob rau hauv kev lag luam uas corrosion kuj tseem ceeb heev, xws li tsheb los yog marine daim ntaub ntawv, lub xub ntiag ntawm voids tuaj yeem cuam tshuam tag nrho lub neej ntev thiab kev ua haujlwm ntawm cov khoom siv welded.
- Txo kev zoo nkauj tsis txaus ntseeg: Kev sib xyaw ua ke tsis tiav feem ntau ua rau muaj qhov tsis sib xws lossis tsis zoo. Qhov kev kho kom zoo nkauj no tsis tuaj yeem ua tau raws li qhov xav tau ntawm cov qauv pom, tshwj xeeb tshaj yog nyob rau hauv cov ntawv thov uas muaj kev zoo nkauj yog qhov tseem ceeb, xws li cov neeg siv khoom lossis cov qauv tsim vaj tsev. Lub xub ntiag ntawm voids tuaj yeem txo qhov kev pom zoo tag nrho ntawm qhov vuam, cuam tshuam qhov pom zoo ntawm cov khoom tiav.
Hais txog qhov tsis zoo ntawm qhov tsis tiav fusion hauv cov txiv ntoo vuam tshuab yog qhov tseem ceeb kom ntseeg tau tias muaj kev ntseeg tau thiab muaj zog welds. Los ntawm kev siv cov txheej txheem vuam kom zoo, txhim kho cov txheej txheem tsis zoo, ua kom cov khoom siv hluav taws xob txaus, thiab txhawb kev sib koom ua ke zoo, cov welders tuaj yeem txo qhov tshwm sim ntawm qhov tsis tiav fusion. Qhov no txhim kho kev sib koom ua ke lub zog, tsis kam tiv thaiv, qaug zog kev ua haujlwm, kev tiv thaiv corrosion, thiab kev thov kom zoo nkauj, ua rau cov txiv ntoo zoo welds uas ua tau raws li cov qauv kev lag luam thiab cov neeg siv khoom xav tau.
