Kupyolera mu kuyang'ana, sikovuta kupeza izo nthawi iliyonsemapaipi achitsulo okhuthala, mapaipi okongoletsedwa thermally, etc. amapangidwa, strip zitsulo ntchito monga kupanga zopangira, ndipo mapaipi otengedwa ndi kuwotcherera wandiweyani-mipanda pa zipangizo kuwotcherera mkulu pafupipafupi amatchedwa mipope wandiweyani-mipanda zitsulo. Pakati pawo, malingana ndi ntchito zosiyanasiyana komanso njira zosiyanasiyana zopangira kumbuyo, amatha kugawidwa m'machubu a scaffolding, machubu amadzimadzi, ma waya, machubu a bulaketi, machubu a guardrail, etc.). Standard kwa wandiweyani-mipanda welded mapaipi GB/T3091-2008. Mapaipi amadzimadzi okhathamira pang'ono ndi mtundu wa mapaipi opindika okhala ndi mipanda. Nthawi zambiri amagwiritsidwa ntchito ponyamula madzi ndi gasi. Pambuyo kuwotcherera, palinso kuyesa kumodzi kwa hydraulic kuposa mapaipi wamba owotcherera. Chifukwa chake, mapaipi amadzimadzi ocheperako amakhala ndi makoma okulirapo kuposa mapaipi wamba otsekedwa. Zolemba za welded zitoliro nthawi zambiri zimakhala zokwera pang'ono.

Miyezo yowunikira mapaipi achitsulo okhala ndi mipanda yolimba imaphatikizapo mfundo izi:
1. Mipope yachitsulo yokhala ndi mipanda yolimba iyenera kutumizidwa kuti iwunikidwe m'magulu, ndipo malamulo ophatikizira amayenera kutsatira malamulo azinthu zofananira.
2. Zinthu zoyang'anira, kuchuluka kwa zitsanzo, malo opangira zitsanzo, ndi njira zoyesera zamapaipi achitsulo okhala ndi mipanda yolimba zizikhala ndi malamulo azomwe zimapangidwira. Ndi chilolezo cha wogula, mapaipi achitsulo osakanizika opanda msoko amatha kutsatiridwa m'magulu malinga ndi nambala yozungulira.
3. Ngati zotsatira za mayeso a mipope yazitsulo zolimba-mipanda sizikukwaniritsa zofunikira za mankhwala, osayenerera ayenera kusankhidwa, ndipo chiwerengero cha zitsanzo chiyenera kusankhidwa mwachisawawa kuchokera pamtanda womwewo wa mipope yazitsulo zolimba-mipanda. kuchita zinthu zosayenera. kuyenderanso. Ngati zotsatira zowunikiranso zalephera, mtanda wa mipope yazitsulo zolimba-mipanda sudzaperekedwa.
4. Kwa mipope yachitsulo yokhala ndi mipanda yokhala ndi zotsatira zosayenerera zowunikiranso, woperekayo akhoza kuwapereka kuti awonedwe chimodzi ndi chimodzi; kapena atha kulandiranso chithandizo cha kutentha ndikutumiza gulu latsopano kuti liwunikenso.
5. Ngati palibe zofunikira zapadera pazomwe zimapangidwira, mankhwala omwe amapangidwa ndi mipope yazitsulo zolimba-mipanda adzayang'aniridwa molingana ndi kusungunuka kwake.
6. Kuyang'ana ndi kuyang'anira mapaipi azitsulo zolimba-mipanda ayenera kuchitidwa ndi dipatimenti yoyang'anira luso la wothandizira.
7. Woperekayo ali ndi malamulo owonetsetsa kuti mapaipi achitsulo opangidwa ndi mipanda yokhuthala akugwirizana ndi zomwe zimapangidwira. Wogula ali ndi ufulu woyendera ndi kuyang'anira molingana ndi zomwe zimafunikira.

Kuphatikiza apo, pali zinthu zina zomwe tiyenera kudziwa zokhudza kuwotcherera mapaipi achitsulo okhala ndi mipanda:
1. Kuwotcherera kutentha kwa mapaipi achitsulo okhuthala-mipanda: Kutentha kwa kuwotcherera kumakhudzidwa ndi mphamvu yamagetsi yamagetsi yamagetsi yamagetsi. Malingana ndi ndondomekoyi, mphamvu yamagetsi yamagetsi yamagetsi yamagetsi imakhudzidwa ndi mafupipafupi omwe alipo. The eddy panopa matenthedwe mphamvu ndi molingana ndi lalikulu la kulimbikitsa pafupipafupi; Mafupipafupi amakono olimbikitsa amakhudzidwa ndi mphamvu ya stimulation, panopa, capacitance, ndi inductance. Njira yolimbikitsira pafupipafupi ndi:
f=1/[2π(CL)1/2]…(1) Mu chilinganizo: f-kulimbikitsa pafupipafupi (Hz); C-capacitance mu chilimbikitso loop (F), capacitance = mphamvu / voteji; L-chilimbikitso loop Inductance, inductance = maginito flux/panopa, zitha kuwoneka kuchokera ku formula yomwe ili pamwambapa kuti ma frequency osangalatsa amafanana ndi muzu wapakati wa capacitance ndi inductance mu dera losangalatsa, kapena molingana ndi muzu wapakati wa magetsi ndi magetsi. Malingana ngati capacitance, inductance, kapena voteji ndi zamakono mu dera zimasinthidwa, Kukula kwa mafupipafupi othamanga kungasinthidwe kuti akwaniritse cholinga chowongolera kutentha kwa kuwotcherera. Pakuti otsika mpweya zitsulo, kuwotcherera kutentha umalamulidwa pa 1250 ~ 1460 ℃, amene angathe kukwaniritsa zofuna kuwotcherera malowedwe chitoliro khoma makulidwe a 3 ~ 5mm. Komanso, kutentha kuwotcherera akhoza angapezeke mwa kusintha liwiro kuwotcherera. Pamene kutentha kolowera sikukukwanira, m'mphepete mwawotchiyo sichitha kufika kutentha kwazitsulo, ndipo mawonekedwe achitsulo amakhalabe olimba, zomwe zimapangitsa kusakanikirana kosakwanira kapena kulowa kosakwanira; pamene kutentha kolowera sikuli kokwanira, m'mphepete mwawotchiyo umadutsa kutentha kwambiri, zomwe zimapangitsa kuti madontho amoto asungunuke kwambiri kapena osungunuka apangitse weld kupanga dzenje losungunuka.

2. Kuwongolera kwapakati pa mipope yachitsulo yokhala ndi mipanda yokhuthala: Tumizani chitsulo chamzere mu chitoliro chowotcherera, ndikuchigudubuza ndi ma roller angapo. Chitsulo chachitsulocho chimakulungidwa pang'onopang'ono kupanga chubu chozungulira chopanda kanthu ndi mipata yotseguka. Sinthani kuthamanga kwa wodzigudubuza wokanda. Kuchulukaku kuyenera kusinthidwa kuti kusiyana kwa weld kuyendetsedwe pa 1 ~ 3mm ndipo malekezero onse a weld asungunuke. Ngati kusiyana kuli kwakukulu, zotsatira zapafupi zidzachepetsedwa, kutentha kwamakono kwa eddy sikudzakhala kokwanira, ndipo mgwirizano wa inter-crystal wa weld udzakhala wosauka, zomwe zimapangitsa kuti zisawonongeke kapena kusweka. Ngati kusiyana kuli kochepa kwambiri, zotsatira zapafupi zidzawonjezeka, ndipo kutentha kwa kuwotcherera kudzakhala kwakukulu, kumapangitsa kuti weld awotchedwe; kapena kuwotcherera kudzapanga dzenje lakuya pambuyo poumidwa ndi kukulungidwa, zomwe zimakhudza pamwamba pa weld.
