Cov txheej txheem rau Mitigating Vuam Stress nyob rau hauv nruab nrab Frequency Spot Vuam Machine

Vuam kev nyuaj siab, ib qho tshwm sim los ntawm cov txheej txheem vuam nyob rau hauv nruab nrab zaus qhov chaw vuam tshuab, tuaj yeem cuam tshuam qhov kev ncaj ncees ntawm cov khoom siv welded. Qhov tsab xov xwm no tshawb nrhiav txoj hauv kev zoo rau kev txo cov kev ntxhov siab vim kev ntxhov siab, ua kom muaj kev ntseeg siab thiab ua haujlwm ntev ntawm cov pob qij txha welded.

1. Pre-Welding Planning thiab Tsim:Kev xav sib koom ua ke tsim thiab xaiv cov khoom siv ua lub luag haujlwm tseem ceeb hauv kev faib kev ntxhov siab sib npaug thoob plaws thaj tsam welded. Cov pob qij txha tsim tau zoo tuaj yeem pab txo qis cov ntsiab lus kev ntxhov siab.
2. Tom qab Weld Thaum tshav kub kub kho:Tswj kev kho cua sov, xws li kev ntxhov siab nyem annealing, tuaj yeem siv tau tom qab vuam los txo cov kev ntxhov siab seem. Qhov ntsuas kub siab pab kom cov khoom so kom txaus thiab txo cov kev ntxhov siab.
3. Vibration Stress Relief:Kev siv cov kev co tswj kev vibrations tom qab vuam tuaj yeem ua rau muaj kev ntxhov siab hauv cov khoom thiab txhawb kev ntxhov siab. Txoj kev no tuaj yeem ua tau zoo tshwj xeeb hauv kev txo cov kev ntxhov siab.
4. Peening:Mechanical peening muaj kev tawm tsam ntawm qhov chaw welded nrog tswj quab yuam kom induce compressive stresses uas counteract tensile welding stresses. Txoj kev no txhim kho cov khoom tiv thaiv kom tawg thiab qaug zog.
5. Tswj Cov Cuab Yeej Cuab Yeej:Kev ua raws li cov kev tswj kom txias, xws li kev ua kom txias qeeb lossis siv cov khoom siv insulating, tuaj yeem pab tiv thaiv kev hloov pauv kub sai thiab txo qhov sib txawv ntawm kev ntxhov siab.
6. Backstep Vuam:Cov txheej txheem no suav nrog kev vuam nyob rau hauv qhov kev txiav txim rov qab, pib los ntawm qhov chaw thiab nce mus rau sab nraud. Backstep welding pab faib cov thermal kev nyuab siab sib npaug, txo qhov kev pheej hmoo ntawm kev ntxhov siab.
7. Weld Sequence Optimization:Kho qhov sib txuas ntawm vuam, xws li kev sib hloov ntawm sab lossis ntu, tuaj yeem pab faib kev ntxhov siab thiab tiv thaiv cov tsub zuj zuj ntawm cov kev ntxhov siab seem.

Ua tau zoo txo ​​qhov kev ntxhov siab ntawm vuam hauv nruab nrab zaus qhov chaw vuam tshuab yog qhov tseem ceeb rau kev ua kom lub neej ntev thiab kev ntseeg siab ntawm cov pob qij txha welded. Los ntawm kev ua haujlwm ua ke ntawm kev npaj ua ntej-weld, tswj kev kho cua sov, kev co kev ntxhov siab nyem, peening, tswj cov txheej txheem txias, thiab cov txheej txheem vuam zoo, cov vuam-vim kev ntxhov siab tuaj yeem txo qis. Cov txheej txheem no koom ua ke los txhim kho cov khoom tsim kev ncaj ncees, txo qhov kev pheej hmoo ntawm deformation, tawg, thiab ua tsis tiav ntxov, thiab thaum kawg ua cov welds zoo.
