Inkqubo yeWelding yesakhelo sendawo yentsimbi

1.Iimfuno zomgangatho wesakhelo sendawo yebhola ebholitiweyo kunye namacandelo imathiriyeli yebha: Ubude obungacwangciswanga kunye nempazamo yokuwelda yombhobho wentsimbi kunye nebha zingaphakathi kwe ± 1mm Ibhola yeBolt: Akufuneki kubekho iintanda kumphezulu, impazamo yomgama ukusuka embindini webhola ukuya kwibhola. umphezulu womngxuma Screw ungaphakathi ± 10.2mm, kwaye ukutenxa engile yomngxuma screw yi ± 30′.I-Welding kufuneka iqhutywe ngokwe-GBJ97-81: i-welding of components kufuneka ibe namandla alinganayo, kwaye umgangatho we-welding kufuneka ulawulwe ngokungqongqo.Ibhola kufuneka ifudunyezwe kwi-50 ° ngaphambi kokuba i-welding kunye ne-5016 okanye i-5015 electrode.

I-2.Ibakala lekhwalithi ye-Weld: uxhulumaniso lwe-weld phakathi kwepleyiti yokuxhasa, ibhola yebholiti kunye ne-embedded part plate yonke i-welded, ibakala lomgangatho li-2, kwaye abanye 3. Imidwebo yokwakha kufuneka ifikelele kwinqanaba lesibini.

3. Intsimbi esetyenziswe kwisakhiwo somthwalo siya kuba nobungqina bokuqina kwamandla, ukunyuswa, amandla okuvelisa kunye nesulfure kunye nomxholo we-phosphorus, kunye nesakhiwo esidibeneyo siya kuba nobungqina bekhabhoni.Intsimbi esetyenziselwa i-welded load-bearing structures kunye nezakhiwo ezibalulekileyo ezingenayo i-welded ezithwala umthwalo kufuneka nazo zibe nesiqinisekiso sokufaneleka sovavanyo lokugoba.

4.Ukuhlolwa komgangatho we-welding seam yezakhelo zendawo kufuneka zihlangabezane neemfuno zomgangatho wesibini ezichazwe kwi-<> (GB50205-2020).

5. Umgangatho womgangatho we-weld uya kuhambelana nomgangatho wangoku wesizwe "I-Code ye-Welding of Steel Structures" GB 50661 Indlela yokuhlola iya kuhambelana nomgangatho wangoku welizwe "iKhowudi yoKwamkeleka koMgangatho woKwakha woBunjineli beSteel Structure" GB 50205. Kwii-butt welds ezinobunzima obungaphantsi kwe-6mm, ukufumanisa i-flaw ye-ultrasonic akuyi kusetyenziswa ukumisela umgangatho we-weld grade.6.Xa umbhobho wentsimbi kunye nepleyiti yokutywina kunye nentloko yekhowuni zenza intonga, i-butt welds kuzo zombini iziphelo ziyi-welds zokungena ezigcweleyo.

ukuwelda:

Inkqubo ye-welding yinkqubo ebalulekileyo ekuveliseni isakhelo sendawo yentsimbi, kwaye kufuneka iqhutywe ngokuhambelana ngokungqongqo nemiyalelo yokusebenza kwe-welding.Ukunciphisa uxinzelelo olushiyekileyo olubangelwa yi-welding, kwaye ulungise kwangexesha uguquko ngokufudumeza ilangatye.

A. Xa umbhobho wentsimbi udityaniswe kunye nepleyiti yokutywina kunye nombhobho wentsimbi, i-groove iya kuvulwa ngokweemfuno, kwaye i-angle ye-groove iya kuhlangabezana neemfuno ze-engile eyenziwe phakathi kwe-electrode kunye ne-groove surface ukuze kuthintelwe ukuchithwa kunye nokudibanisa. ukubandakanywa kwe-slag.Ukongezelela, i-gap ye-groove kufuneka ibe nkulu ngokwaneleyo ukwenzela ukuba i-electrode arc ikwazi ukufikelela ngaphantsi kwe-groove kwaye igweme ubunzulu bokungena ngokwaneleyo.
B. Gwema ukubeka i-welding seam phakathi kwentonga xa umbhobho wensimbi uhlanjululwa.
C. Imiba efuna ingqwalasela kumsebenzi wokuwelda:
a.Ngexesha le-arc welding manual, uluhlu lokuhambisa akufanele lube lukhulu kakhulu, kwaye i-multi-pass kunye ne-multi-layer welding isetyenziswa.
Ngethuba lenkqubo, i-weld bead okanye i-interlayer welding slag, ukufakwa kwe-slag, i-oxide, njl. Kufuneka isuswe ngokuthe ngqo.Ivili lokugaya, intsimbi ingasetyenziswa.
Izixhobo ezifana neebrashi zocingo.
b.I-welding seam efanayo kufuneka idityaniswe ngokuqhubekayo kwaye igqitywe ngexesha elinye.
c.Kwimidibaniso eyahlukeneyo ye-weld, emva kokuba i-welding igqityiwe, i-slag kunye ne-spatter yensimbi ebusweni be-weld kufuneka ihlambuluke.
Jonga umgangatho wembonakalo ye-weld, kwaye akufuneki kubekho uxinzelelo, i-weld bead, i-undercut, i-blowhole, ukungabikho kwe-fusion, i-crack.
kunye nezinye iziphene zikhona.
d.Emva kokuba i-butt weld idityanisiwe, ukubonwa kwe-ultrasonic flaw kufuneka kuqhutywe emva kweeyure ezingama-24.
