Kupititsa patsogolo luso ndi khalidwe ndizofunikira pamakampani opanga zinthu zolemetsa omwe akusintha. Chimodzi mwazofunikira kwambiri paukadaulo wazowotcherera chomwe chatuluka m'zaka zaposachedwa ndi kuwotcherera kwa arc kuwirikiza kawiri (DSAW). Ukadaulo waukadaulo uwu sikuti umangowonjezera kukhazikika kwazinthu zowotcherera, komanso kufewetsa njira yopangira, ndikupangitsa kuti ikhale yosintha masewera kwa mafakitale omwe amadalira zida zolemetsa.
Pamtima pa DSAW ndikutha kwake kupanga ma welds apamwamba kwambiri okhala ndi zolakwika zochepa. Njirayi imaphatikizapo ma arcs awiri omwe amakwiriridwa pansi pa granular flux, yomwe imateteza dziwe la weld kuti lisaipitsidwe ndi oxidation. Zotsatira zake zimakhala zoyera, zowotcherera zolimba zomwe zimatha kupirira zovuta za ntchito zopangira zinthu zolemetsa. Izi ndizofunikira makamaka kwa makampani omwe amapangaozizira anapanga welded structuralzigawo zopanda kanthu, monga zomwe zafotokozedwa mumiyezo yaku Europe mumitundu yozungulira, masikweya kapena amakona anayi. Magawowa ndi ofunikira pamagwiritsidwe osiyanasiyana, kuphatikiza zomangamanga, zomangamanga ndi makina olemera.
Ili ku Cangzhou, m'chigawo cha Hebei, chomeracho chikuwonetseratu ubwino wa DSAW pakupanga katundu wolemera. Yakhazikitsidwa mu 1993, chomeracho chimakwirira kudera la 350,000 masikweya mita ndipo chili ndi chuma chonse cha yuan 680 miliyoni. Pokhala ndi antchito odzipereka okwana 680, chomerachi ndi chotsogola pakupanga magawo apamwamba kwambiri opanda kanthu. Mwa kuphatikiza DSAW pakupanga, mbewuyo yasintha kwambiri magwiridwe antchito komanso mtundu wazinthu.
Chimodzi mwazabwino zazikulu za DSAW ndi liwiro. Njirayi imalola kuthamanga kwachangu kwambiri kuposa njira zachikhalidwe, zomwe zimachepetsa nthawi yopanga. Kuchita bwino kumeneku ndikofunikira kwambiri pakupanga zinthu zolemetsa pomwe nthawi imakhala yofunika kwambiri. Pochepetsa nthawi yowotcherera, opanga amatha kuwonjezera kupanga ndikukwaniritsa zomwe msika wampikisano umafunikira.
Kuphatikiza apo, mtundu wa weld wa DSAW umakhalabe wapamwamba kwambiri. Njira ya arc yomwe ili pansi pamadzi imachepetsa chiopsezo cha zolakwika monga porosity ndi inclusions zomwe zingasokoneze kukhulupirika kwapangidwe kwa chinthu chomaliza. Izi ndizofunikira makamaka pazigawo za dzenje zozizira, zomwe ziyenera kukwaniritsa mfundo zokhwima kuti zitsimikizire chitetezo ndi kudalirika kwa ntchito zawo. Chomera cha Cangzhou chimagwiritsa ntchito ukadaulo uwu kuti zitsimikizire kuti zogulitsa zake sizimangokwaniritsa miyezo yamakampani, koma zimapitilira.
Kuphatikiza pakuwongolera bwino komanso kuwongolera bwino, DSAW imathandizanso kusunga ndalama. Pokhala ndi zolakwika zochepa, pamakhala kufunikira kocheperako, zomwe zikutanthauza kuti opanga amatha kugawa zinthu moyenera. Izi ndizopindulitsa makamaka pakupanga kwakukulu, komwe ndalama zakuthupi ndi ntchito ndizofunikira kwambiri pakuwononga ndalama zonse zopangira.
Pamene makampani olemera opangira zinthu akupitilira kukula, kukhazikitsidwa kwaukadaulo wowotcherera wapamwamba mongakawiri kumizidwa arc weldedadzakhala ndi mbali yofunika kwambiri yokonza tsogolo. Makampani omwe amagulitsa ukadaulo uwu samangopititsa patsogolo magwiridwe antchito komanso kukulitsa mtundu wazinthu, motero amapeza malo otsogola pamsika wampikisano kwambiri.
Mwachidule, kuwotcherera kwa arc kuwirikiza kawiri kukusintha kupanga kolemera pakuwongolera bwino komanso kuchita bwino. Chomerachi ku Cangzhou City ndi chitsanzo chabwino cha momwe ukadaulo ungaphatikizire bwino pakupanga, kupanga zigawo zapamwamba zapabowo zomwe zimakwaniritsa zosowa zamakampani amakono. Pamene opanga amayesetsa kuchita bwino, kugwiritsa ntchito matekinoloje atsopano monga DSAW kuyenera kukhala kofunikira pazaka zikubwerazi.
