Welded zitsulo chitoliro kupanga ndondomeko ndi zitsulo pepala, Mzere, ndi njira zosiyanasiyana akamaumba ntchito molunjika atolankhani mpukutu kapena helical malangizo kupitanira mu ankafuna mawonekedwe mtanda-gawo, ndiyeno mwa kutentha, kuthamanga, njira zosiyanasiyana kuwotcherera pamodzi kuti. kupeza chuma. Choncho, zolakwika mu welded zitsulo chitoliro lagawidwa magawo awiri: zitsulo m`munsi zinthu zolakwika ndi kuwotcherera zilema.

1. Chilema m'munsi mwazitsulo
Zowonongeka za pepala pambuyo pakugubuduza ndi njira zina, zambiri za planar, zofanana ndi pamwamba; kufooka kwawo kwakukulu delamination, inclusions, ming'alu, makutu, etc., amene ndi ambiri wosanjikiza zolakwika mkati. Stratification adzabala zosiyanasiyana ming'alu pamene kumakoka maganizo perpendicular pamwamba pa pepala ndi hierarchical zidzakhudza kwambiri mphamvu ya chitoliro zitsulo, sikuloledwa chilema.

2. Weld zolakwika
Weld chilema amatanthauza chilema pa kuwotcherera kapena pambuyo kuwotcherera chifukwa kuwotcherera agawanika ming'alu, pores, slag, chosakwanira malowedwe, chosakwanira maphatikizidwe, undercut kuwotcherera zilema. Tima weld porosity, slag, etc. wandiweyani-dimensional zilema, ming'alu, kusowa maphatikizidwe ndi zolakwika zina pa nkhani ya lathyathyathya, vuto lalikulu. Mvula slag, kusakwanira malowedwe ndi zolakwika zina pa nkhani ya Mzere, choipa kwambiri. Pores, slag ndi zina zazing'ono ngati zolakwika pamlanduwo. Weld kupunduka mwina chifukwa mphamvu zitsulo, pulasitiki ndi nkhani zina, kwambiri zimakhudza khalidwe la zitsulo, welded zitsulo chitoliro khalidwe zimakhudza mwachindunji ntchito otetezeka ndi moyo utumiki wa mapaipi mafuta ndi mpweya, motero kuyendera kuwotcherera makamaka ming'alu kuwotcherera ming'alu kuwotcherera ming'alu. pores, slag, kulowa kosakwanira, kusakanizika kosakwanira ndi zina zowopsa zozindikira zolakwika.
