Kodi kulowela kwa kuwotcherera ndi chiyani?Amatanthauza kusungunuka kwakuya kwachitsulo choyambira kapena kutsogolo mkanda wowotcherera pamtanda wa olowa.
Malo olumikizirana ndi: weld seam (0A), fusion zone (AB) ndi zone yokhudzidwa ndi kutentha (BC).
Gawo 1: Sample
(1) Kudula udindo wa kuwotcherera chitsanzo cholowera: a.Pewani kuyamba ndi kuyimitsa malo
b.Dulani pa 1/3 ya chiwopsezo cha weld
c.Pamene kuwotcherera chipsera kutalika ndi zosakwana 20mm, kudula pakati pa kuwotcherera chipsera.
(2) Kudula
A. Lumikizani magetsi ndikuwona ngati zida zoyezera zikukwaniritsa zofunikira zoyeserera;Monga momwe tawonetsera pa Chithunzi 1, tsegulani nyumba yotetezera ya makina ocheka a metallographic ndikuyika chipika chachitsulo kuti chiyesedwe.
(Zindikirani: Onetsetsani kuti mwakonza chipika chachitsulo kwathunthu!)
b.Monga momwe tawonetsera pa Chithunzi 2, tsekani chipolopolo chotetezera cha makina ocheka a metallographic, tsegulani valavu yamadzi, ndi kuyatsa chosinthira mphamvu;Gwirani chogwirira cha makina odulira zitsulo ndikuchikanikiza pansi pang'onopang'ono kuti mudule chitsanzo chachitsulo.Pambuyo kudula, kutalika, m'lifupi ndi kutalika kwa chitsanzo chachitsulo kudzakhala kosakwana 4mm;Tsekani valavu yamadzi, zimitsani mphamvu, ndikutulutsa chitsanzo chachitsulo.

Gawo 3: Zidzimbiri
(1) Monga momwe tawonetsera mkuyu 5, gwiritsani ntchito mowa wamtheradi ndi asidi wa nitric pokonzekera njira yowonongeka (3-5% nitric acid ndi mowa) mu kapu yoyezera, ikani chitsanzo chachitsulo muzitsulo zowononga kapena gwiritsani ntchito burashi yaying'ono kuti mutsuke. odulidwa pamwamba kuti dzimbiri.Nthawi ya dzimbiri ndi pafupifupi masekondi 10-15, ndipo zotsatira za dzimbiri zimayenera kuyang'aniridwa ndi maso.
(2) Monga momwe tawonetsera mkuyu 6, pambuyo pa dzimbiri, chotsani chipika chachitsulo ndi tweezers (zindikirani: musakhudze madzi owononga ndi manja), ndipo yeretsani njira yowonongeka pamwamba pa chitsulo chachitsulo choyera. madzi.
(1) Patsani mouma

| L≤8 | Pamwamba pa 0.2 * L |
| L＞8 | pamwamba 1.5 mm |
(2) Muyezo wowotcherera wolowera (mtunda a ndi b ndi kulowa kwa kuwotcherera)
(3) Zida zowunikira zowotcherera
Khwerero 5: Lipoti lowunika momwe kuwotcherera ndi kusungirako zitsanzo
(1) Lipoti loyang'ana zowotcherera:
a.Kuwonjezedwa kwa chithunzi cha gawo loyang'aniridwa
b.Chongani momwe kuyezera kwa kuwotcherera kulowa mu chithunzi
c.Kuwonjezera deta
(2) Malamulo osungiramo zitsanzo zowotcherera:
a.Kusungirako magawo a chimango S kwa zaka 13
b.Zigawo zonse ziyenera kusungidwa kwa zaka zitatu
c.Ngati tatchulidwa mwanjira ina, idzagwiritsidwa ntchito molingana ndi zofunikira zojambula
(Malo owunikira olowera amatha kumamatira ndi zomatira zowonekera kuti achedwetse dzimbiri)
