Zinthu zaweldzolakwika

(1) Zinthu zakuthupi:

Zomwe zimatchedwa zakuthupi zimatanthawuza zitsulo zowotcherera zoyambira ndi zida zowotcherera zomwe zimagwiritsidwa ntchito, monga mawaya, ndodo, flux, ndi mpweya wotchingira ndi zina zotero.Zida zonsezi zimakhudzidwa mwachindunji ndi matope owotcherera kapena physico-chemical reaction of the fusion zone, pomwe zida zoyambira pakuchita bwino kwa zinthuzo, zone-zone kutentha kwapawiri kuukira kotsimikizika.Pa zikuchokera ndi katundu weld zitsulo ndi chinthu chofunika kwambiri pa kuwotcherera zinthu bwino ntchito.Zipatso zabwino ndi m'munsi zitsulo kuwotcherera zipangizo mismatch, osati kungayambitse zosiyanasiyana zolakwika mu weld zone kwa mizere, pores, etc., ndipo akhoza kupezeka kuchokera embrittlement, dzimbiri zosagwira katundu kuti afewetse kapena kusintha.Choncho, pofuna kuonetsetsa wabwino weld olowa ayenera zonse chidwi zinthu zakuthupi.

(2) Zinthu zamakono:

Zochita zambiri zatsimikizira kuti zitsulo zamtundu womwewo m'njira zosiyanasiyana zowotcherera komanso njira zoyezera zinthu, mawonekedwe awotcherera adzawonetsa kusiyana kwakukulu.Bwanji khalidwe la kuwotcherera njira ya kuwotcherera waukulu zotheka mbali ziwiri: Choyamba, makhalidwe kuwotcherera gwero kutentha, amene ndi mphamvu kachulukidwe, pazipita Kutentha kutentha, mphamvu mlingo, etc., iwo akhoza kusintha magawo a kuwotcherera matenthedwe mkombero mwachindunji, monga mzere mphamvu, mkulu-kutentha zogona nthawi, gawo kusintha kutentha osiyanasiyana mlingo kuzirala.Izi ndithudi zidzakhudza microstructure ndi katundu wa mafupa;Kachiwiri ku dziwe ndi dera lapafupi chitetezo, monga slag chitetezo, mpweya, mpweya - slag olowa chitetezo kapena kuwotcherera mu vacuum, zomwe zingakhudze ndondomeko kuwotcherera zitsulo.Mwachionekere, ndondomeko kuwotcherera matenthedwe ndi metallurgical njira khalidwe ndi ntchito mosalephera mafupa zimakhudza kwambiri.
