Zopanda malireMtengo wa ERWimagawidwa mu geometric yopanda msoko komanso yopanda msoko.Chitoliro chachitsulo cha ERW chosasunthika cha geometric ndikuchotsa ma burrs amkati ndi akunja.
Popeza kapangidwe ka mkati mwa dongosolo lochotsa burr ndi chida chowongolera mosalekeza ndi ungwiro, chitoliro chachitsulo chapakati ndi chachikulu mkati mwa kuchotsa burr chakhala chabwino.Mkati burr akhoza kulamulidwa mu -0.2mm ~ + O.5mm kotero.Amatanthauza thupi lopanda msokono weld microstructure mkati, pali kusiyana pakati pa zinthu m'munsi ndi weld m'dera chifukwa utachepa makina katundu, kufunika kuchitapo kanthu kuti yunifolomu ndi zogwirizana luso.ERW zitsulo chitoliro ndi mkulu-pafupipafupi kuwotcherera matenthedwe ndondomeko ndi chifukwa kutentha gradient, amene ali pafupi m'mphepete chubu ndi kupanga zone osungunuka, theka-wosungunuka zone, kutenthedwa minofu, malo normalized, madera osati normalizing, tempering madera. wa gawo la mawonekedwe.Zomwe zimatenthetsa minofu yozungulira chifukwa cha kutentha kwa soldering pamwamba pa 1000℃, mbewu ya austenite yomwe imakula kwambiri m'mikhalidwe yozizira idzapanga gawo lolimba komanso losasunthika la crystalline, kuwonjezera pa kukhalapo kwa kutentha kumatulutsa kupanikizika.Chifukwa chake, mapangidwe a weld zone otsika kuposa zitsulo zamakina am'munsi mwazomwe zimachitika ndi njira yochizira yotenthetsera yowotcherera yomwe imagwiritsa ntchito chipangizo chotenthetsera chotenthetsera chomwe chimatenthetsera AC3 (927).℃), ndiye 60m kutalika, liwiro 20m / min pa mpweya kuzirala, madzi kuzirala pakufunika.Njirayi imagwiritsidwa ntchito pokwaniritsa kuthetsa kupsinjika, kufewetsa ndikuwongolera bungwe kuti lipititse patsogolo zolinga zamakina a HAZ.Pakadali pano, gawo lotsogola padziko lonse lapansi la ERW lakhala likugwiritsidwa ntchito kwambiri pokonza weld lapeza zotsatira zabwino.Quality sitinganene kuti osati ERW chitoliro welds ndi kuwotcherera koyefidi 1, kukwaniritsidwa kwa mabungwe m'chigawo cha weld ndi m'munsi zitsulo machesi.
