Sing'anga mpweya zitsulo zambiri amatanthauza mpweya zili za 0,25 kuti 0.60% mpweya zitsulo.Manual arc kuwotcherera kwa mpweya zitsulo kuponyera ndi kuwotcherera mbali yaikulu motere:

(1) Chitsulo choyambira pafupi ndi chowotcherera chomwe chimakhala ndi pulasitiki yotsika ya minofu yolimba.The apamwamba carbon okhutira, mbale makulidwe, m'pamenenso chizolowezi anaumitsa.Weldment stiffer, kuzirala msanga ndi kusankha ndodo si nthawi, sachedwa kuzizira kusweka.

(2) Popeza chitsulo m'munsi chinasungunuka mu gawo loyamba la weld zitsulo chiŵerengero cha pafupifupi 30%, kotero apamwamba mpweya zili weld, zotsatira zake n'zosavuta kuwotcherera zitsulo otentha akulimbana ndi ozizira akulimbana.

Miyezo yotengedwa ndi kuwotcherera kwa chitsulo cha kaboni

(1) Ngati n'kotheka, sankhani maelekitirodi otsika kwambiri a haidrojeni.Maelekitirodi oterowo ndi kukana kwakukulu kukana kuzizira kwamphamvu kwa kutentha kwamphamvu.milandu payekha, mosamalitsa kulamulira kutentha preheating ndi kuchepetsa kuchepetsa m`munsi zitsulo malowedwe weld mpweya zili ndi njira zina ndondomeko, ntchito kashiamu ilmenite mtundu elekitirodi akhoza kupezanso zotsatira zogwira mtima.Pamene mphamvu welded mfundo ndi m'munsi zitsulo sikutanthauza nthawi yofanana ayenera kugwiritsidwa ntchito otsika kwambiri zofunika otsika ma elekitirodi haidrojeni.Izi Weld Weld pulasitiki, kutulutsa ozizira akulimbana ndi matenthedwe akulimbana zosaopsa kwambiri.

(2) Preheat waukulu matekinoloje miyeso kuwotcherera ndi kukonza kuwotcherera mpweya zitsulo, makamaka makulidwe a weldment, rigidity ndi lalikulu, kutentha-mmwamba mokomera kuchepetsa pazipita kuuma zone anakhudzidwa kutentha ndi kupewa kuzizira akulimbana, ndipo akhoza kusintha pulasitiki yogwirizana.Kutenthetsa kwathunthu ndi kutentha koyenera kumachepetsanso kupsinjika kotsalira kwa post weld.The carbon zili zosiyanasiyana kuwotcherera mpweya zitsulo kuwotcherera kutentha preheat ndipo palibe malamulo yunifolomu.Izi si chifukwa kusankha preheating kutentha anatsimikiza ndi mpweya zili elekitirodi, komanso amakhudzidwa ndi zinthu zina, monga kukula ndi makulidwe a weldment, kuwotcherera mtundu, magawo kuwotcherera ndi kuuma kwa dongosolo ndi choncho.
