1. Kuyerekeza njira zopangira
Njira yopangirachitoliro chachitsulo cholunjika cha msokondi yosavuta. Njira zazikulu zopangira ndi msoko wowongoka wolumikizidwa pafupipafupichitoliro chachitsulondichitoliro chachitsulo cholumikizidwa molunjika cha arcChitoliro chachitsulo cholunjika chokhala ndi msoko chimakhala ndi ntchito yabwino kwambiri, mtengo wotsika komanso chitukuko chachangu.
Mphamvu yachitoliro chachitsulo chozunguliranthawi zambiri imakhala yokwera kuposa ya chitoliro chachitsulo cholunjika. Njira yayikulu yopangira ndi kuwotcherera arc pansi pamadzi. Machubu achitsulo ozungulira amatha kupanga machubu olumikizidwa okhala ndi ma billets osiyanasiyana a mulifupi womwewo, kapenamachubu olumikizidwayokhala ndi mainchesi akuluakulu ochokera ku ma billets opapatiza.
Komabe, poyerekeza ndi mapaipi achitsulo olunjika okhala ndi msoko womwewo, kutalika kwa kuwotcherera kwawonjezeka ndi 30% ndi 100% motsatana, ndipo liwiro lopanga ndi lotsika. Chifukwa chake, mapaipi achitsulo akuluakulu okhala ndi m'mimba mwake nthawi zambiri amawotcherera ndi kuwotcherera kozungulira, ndipo mapaipi ang'onoang'ono achitsulo okhala ndi m'mimba mwake nthawi zambiri amawotcherera ndi kuwotcherera kolunjika.
Mukamapangamapaipi achitsulo olunjika okhala ndi msoko waukuluMu mafakitale, ukadaulo wowotcherera wofanana ndi T umagwiritsidwa ntchito, kutanthauza kuti, mapaipi ochepa achitsulo olunjika amalumikizidwa ndi kulumikizidwa kuti akwaniritse kutalika kofunikira kwa polojekitiyi. Zolakwika za chitoliro chachitsulo chowongoka chofanana ndi T zidzawonjezeka kwambiri, ndipo mphamvu yotsala ya welding ya weld yofanana ndi T ndi yayikulu. Chitsulo chowotcherera nthawi zambiri chimakhala ndi triaxial stress, zomwe zimapangitsa kuti pakhale ming'alu.
Kuphatikiza apo, malinga ndi malamulo aukadaulo okhudza kuwotcherera arc pansi pa nthaka, weld iliyonse iyenera kumenyedwa ndi arc striking ndi arc extinguished treatment. Komabe, chitoliro chilichonse chachitsulo sichingakwaniritse izi panthawi yowotcherera msoko wozungulira, kotero zolakwika zambiri zowotcherera zingachitike panthawi yozimitsa arc.
2. Kuyerekeza magawo a magwiridwe antchito
Pamene chitolirocho chikukakamizidwa mkati, nthawi zambiri pamakhala kupsinjika kwakukulu kuwirikiza kawiri, komwe ndi kupsinjika kwa radial ndi kupsinjika kwa axial. Kupsinjika kwakukulu pa weld, komwe α Ndi ngodya yozungulira ya weldchitoliro chachitsulo chozungulira.
Kupsinjika kwakukulu pa spiral weld ndiye kupsinjika kwakukulu kwa chitoliro chachitsulo cholunjika. Pansi pa kupsinjika komweko kogwira ntchito, makulidwe a khoma la mapaipi achitsulo chozungulira okhala ndi mulifupi wofanana wa chitoliro ndi ochepa kuposa mapaipi achitsulo cholunjika.
