Imigangatho yokuhlola kunye nemiba yokulawula ukuwelda kwimibhobho yentsimbi enodonga olungqingqwa

Ngokuqwalasela, akukho nzima ukufumana oko nanini naimibhobho yentsimbi engqindilili, imibhobho eyandisiweyo eshushu, njl. njl Phakathi kwazo, ngokweendlela ezahlukeneyo zokusetyenziswa kunye neenkqubo ezahlukeneyo zokuvelisa umva, zinokwahlulwa ngokurhabaxa zibe ziityhubhu zescaffolding, iityhubhu zamanzi, iingcingo zocingo, iityhubhu zesibiyeli, iityhubhu zokugada, njl.njl.). Umgangatho wemibhobho edityanisiweyo edityanisiweyo ye-GB/T3091-2008. Imibhobho edityanisiweyo yoxinzelelo olusezantsi luhlobo lwemibhobho edityanisiweyo edityanisiweyo. Ngokuqhelekileyo zisetyenziselwa ukuthutha amanzi kunye negesi. Emva kwe-welding, kukho olunye uvavanyo lwe-hydraulic kunemibhobho edityanisiweyo eqhelekileyo. Ke ngoko, imibhobho yamanzi enoxinzelelo oluphantsi ineendonga ezityebileyo kunemibhobho eqhelekileyo edityanisiweyo. Iingcaphuno zemibhobho edityanisiweyo zihlala ziphezulu kancinci.

Imigangatho yokuhlola imibhobho yentsimbi enodonga olungqingqwa ikakhulu ibandakanya la manqaku alandelayo:
1. Iibhobho zetsimbi ezityebileyo kufuneka zingeniswe ukuze zihlolwe kwiibhetshi, kwaye imigaqo yokudibanisa kufuneka ihambelane nemimiselo yemigangatho yemveliso ehambelanayo.
2. Izinto zokuhlola, ubungakanani besampulu, iindawo zesampulu, kunye neendlela zovavanyo lwemibhobho yentsimbi enodonga olungqingqwa iya kuba yimimiselo yemigaqo yemveliso ehambelanayo. Ngemvume yomthengi, imibhobho yentsimbi engenamthungo eshinyeneyo enodonga olushushu eqengqelekayo inokuthatyathwa ngokweebhetshi ngokwenombolo yengcambu.
3. Ukuba iziphumo zovavanyo lwemibhobho yentsimbi enodonga olungqingqwa ayihlangabezani neemfuno zemigangatho yemveliso, abo bangafanelekanga kufuneka bachongwe, kwaye inani leesampuli eziphindwe kabini kufuneka zikhethwe ngokungenamkhethe kwibhetshi enye yeemibhobho zentsimbi ezityebileyo. ukwenza izinto ezingafanelekanga. ukuhlolwa kwakhona. Ukuba iziphumo zokuhlolwa kwakhona aziphumelelanga, ibhetshi yemibhobho yentsimbi enodonga olungqingqwa ayiyi kuhanjiswa.
4. Kwimibhobho yentsimbi enodonga olungqingqwa kunye neziphumo zokuhlola kwakhona ezingafanelekanga, umthengisi unokuzingenisa ukuze zihlolwe nganye nganye; okanye banokuphinda bafumane unyango lobushushu kwaye bangenise ibhetshi entsha ukuze ihlolwe.
5. Ukuba akukho malungiselelo akhethekileyo kwiinkcukacha zemveliso, ukubunjwa kweekhemikhali zemibhobho yentsimbi enodonga olungqingqwa kuya kuhlolwa ngokuhambelana nokunyibilika.
6. Ukuhlolwa nokuhlolwa kwemibhobho yentsimbi enodonga olungqingqwa kufuneka kuqhutywe lisebe lolawulo lobugcisa bomthengisi.
7. Umthengisi unemigaqo yokuqinisekisa ukuba iibhobho zetsimbi ezityebileyo ezihanjiswayo zihambelana neenkcukacha zemveliso ezihambelanayo. Umthengi unelungelo lokuhlola kunye nokuhlola ngokuhambelana neenkcukacha zempahla yorhwebo.

Ukongeza, kukho ezinye izinto ekufuneka siyazi malunga nolawulo lokuwelda lwemibhobho yentsimbi enodonga olungqingqwa:
1. Ulawulo lobushushu be-welding yemibhobho yentsimbi enodonga olungqingqwa: Ubushushu be-welding buchatshazelwa yi-high-frequency eddy yangoku amandla obushushu. Ngokutsho kwefomula, i-high-frequency eddy yangoku amandla okushisa achaphazelekayo ngokuphindaphindiweyo ngoku. I eddy yangoku amandla thermal ngokomlinganiselo isikwere ye yangoku inkuthazo frequency; I-frequency ye-stimulation yangoku ichaphazelekayo yi-voltage yokuvuselela, yangoku, i-capacitance, kunye ne-inductance. Ifomula yenkuthazo rhoqo yile:
f=1/[2π(CL)1/2]…(1) Kwifomyula: f-encorage frequency (Hz); I-C-capacitance kwi-loop yokukhuthaza (F), i-capacitance = amandla / i-voltage; I-L-encouragement loop Inductance, inductance = i-magnetic flux / yangoku, inokubonwa kwifomyula engentla ukuba i-excitation frequency ihambelana ngokungafaniyo ne-square root ye-capacitance kunye ne-inductance kwi-excitation circuit, okanye ngokuthe ngqo ngokulinganayo kwingcambu yesikwele. i-voltage kunye nombane. Ngethuba nje i-capacitance, i-inductance, okanye i-voltage kunye ne-current in circuit itshintshiwe, Ubungakanani be-excitation frequency inokutshintshwa ukuze kufezekiswe injongo yokulawula ukushisa kwe-welding. Kwintsimbi yekhabhoni ephantsi, ubushushu be-welding bulawulwa kwi-1250 ~ 1460 ℃, enokuthi ihlangabezane neemfuno zokungena kwe-welding yodonga lombhobho we-3 ~ 5mm. Ukongeza, ubushushu be-welding bunokufumaneka ngokulungelelanisa isantya se-welding. Xa igalelo lokushisa linganele, umda ovuthayo we-weld awufikeleli kwiqondo lokushisa, kwaye isakhiwo sensimbi sihlala siqinile, okubangelwa ukudibanisa okungagqibekanga okanye ukungena okungaphelelanga; xa igalelo lobushushu lingonelanga, i-edge eshushu ye-weld idlula iqondo lobushushu le-welding, okukhokelela ekutshisweni ngokugqithisileyo okanye amathontsi anyibilikisiweyo abangela ukuba i-weld yenze umngxuma otyhidiweyo.

2. Ukulawula umsantsa we-weld wemibhobho yentsimbi enodonga olungqingqwa: Thumela intsimbi yomcu kwiyunithi yombhobho odityanisiweyo, kwaye uyiqengqe ngeerola ezininzi. Intsimbi yomcu iqengqeleka kancinci kancinci ukuze yenze iityhubhu engqukuva engenanto enezikhewu ezivulekileyo. Lungisa uxinzelelo lwe-roller yokuxova. Isixa kufuneka sihlengahlengiswe ukuze i-gap ye-weld ilawulwe kwi-1 ~ 3mm kwaye zombini iziphelo ze-weld zigungxulwe. Ukuba i-gap inkulu kakhulu, umphumo osondeleyo uya kuncitshiswa, ukushisa kwangoku kwe-eddy kuya kuba nganelanga, kwaye i-inter-crystal bonding ye-weld iya kuba yimbi, okubangelwa ukungaxutywa okanye ukuqhekeka. Ukuba i-gap incinci kakhulu, umphumo osondeleyo uya kwanda, kwaye ukushisa kwe-welding kuya kuba kukhulu kakhulu, kubangela ukuba i-weld itshiswe; okanye i-weld iya kwenza umngxuma onzulu emva kokuxutywa kunye nokuqengqeleka, okuchaphazela umphezulu we-weld.
