Kuwotcherera kwa chitoliro chachitsulo chowongoka (lsaw/erw):

Chifukwa cha mphamvu ya kuwotcherera pakali pano ndi mphamvu yokoka, kuwotcherera kwa mkati kwa chitoliro kudzatuluka, ndipo weld wakunja nayenso adzagwedezeka.Ngati mavutowa agwiritsidwa ntchito m'malo otsika kwambiri amadzimadzi, sangakhudzidwe.

Ngati imagwiritsidwa ntchito pa kutentha kwakukulu, kuthamanga kwambiri komanso malo othamanga kwambiri amadzimadzi, zingayambitse mavuto.Vutoli liyenera kuthetsedwa pogwiritsa ntchito zida zoyezera weld.

Mfundo yogwirira ntchito ya zida zowotcherera msoko ndi: mandrel okhala ndi mainchesi a 0.20mm ang'onoang'ono kuposa m'mimba mwake mkati mwa chitoliro amayikidwa mu chitoliro chowotcherera, ndipo mandrel amalumikizidwa ndi silinda kudzera pa chingwe cha waya.Kupyolera mu zochita za silinda ya mpweya, mandrel akhoza kusunthidwa mkati mwa malo okhazikika.Mkati mwa kutalika kwa mandrel, seti ya masikono apamwamba ndi apansi amagwiritsidwa ntchito kugudubuza chowotcherera muzoyenda mobwerezabwereza malinga ndi malo a weld.Pansi pa kugwedezeka kwa mandrel ndi mpukutuwo, ma protrusions ndi depressions amachotsedwa, ndipo mizere ya weld ndi contour ya chitoliro imasinthidwa bwino.Nthawi yomweyo monga momwe kuwotcherera kuwongolera, kapangidwe kake kake mkati mwa weld kadzakanikizidwa, komanso kumathandizira kukulitsa kachulukidwe kakapangidwe ka weld ndikuwongolera mphamvu.

Chiyambi cha weld level:

Panthawi yokhotakhota yachitsulo, kuuma kwa ntchito kudzachitika, zomwe sizikugwirizana ndi kukonzanso kwa chitoliro, makamaka kupindika kwa chitoliro.
Panthawi yowotcherera, chowotcherera chimapangidwa powotcherera, ndipo padzakhala zovuta zowotcherera pakuwotcherera, makamaka polumikizana pakati pa weld ndi chitsulo choyambira..Zida zochizira kutentha zimafunikira kuti zithetse kuuma kwa ntchito ndikuwongolera kapangidwe kambewu.
Pakalipano, njira yochizira kutentha yomwe imagwiritsidwa ntchito kwambiri ndi chithandizo chowala cha hydrogen protective atmosphere, ndipo chitoliro chachitsulo chosapanga dzimbiri chimatenthedwa kufika pamwamba pa 1050 °.
Pambuyo pa nthawi yosungira kutentha, mawonekedwe amkati amasintha kuti apange mawonekedwe a yunifolomu austenite, omwe samatulutsa oxidize pansi pa chitetezo cha hydrogen atmosphere.
Zida zomwe zimagwiritsidwa ntchito ndi zida zowunikira pa intaneti (annealing).zida chikugwirizana ndi mpukutu-kupindika kupanga unit, ndi welded chitoliro ndi pansi kuwala njira mankhwala Intaneti nthawi yomweyo.Zida zotenthetsera zimagwiritsa ntchito ma frequency apakati kapena ma frequency apamwamba kuti azitenthetsa mwachangu.
Yambitsani mpweya wabwino wa haidrojeni kapena haidrojeni-nitrogen kuti mutetezedwe.Kuuma kwa chitoliro cha annealed kumayendetsedwa pa 180 ± 20HV, yomwe imatha kukwaniritsa zofunikira pakukonzanso ndikugwiritsa ntchito.
