Kutheni intsimbi yekhabhoni ephezulu kunzima ukuyidibanisa?

I-Carbon Steel ePhezulu i-weldability engalunganga ngenxa yomxholo wekhabhoni ephezulu.Iimpawu ze-welding zezi zilandelayo:
(1)i-thermal conductivity engalunganga, umahluko omkhulu wobushushu phakathi kwendawo ye-weld kunye nenxalenye engatshisiyo.Xa ichibi elityhidiweyo liphola ngokukhawuleza, uxinzelelo lwangaphakathi kwi-weld lunokwenza lula ukuqhekeka.
(2)Inovakalelo ngakumbi ekucimeni kwaye i-martensite yenziwe ngokulula kwindawo ekufutshane nomthungo.Ngenxa yesenzo soxinzelelo lwesakhiwo, ummandla osondeleyo we-seam uvelisa ukuqhekeka okubandayo.
(3) ngenxa yempembelelo yobushushu obuphezulu, iinkozo zikhula ngokukhawuleza, i-carbide kulula ukuqokelela kwaye ikhule kumda wengqolowa, eyenza i-weld ibe buthathaka kwaye amandla okudibanisa i-welding ayancipha.
(4) intsimbi yekhabhoni ephezulu inokuthi ivelise iintanda ezishushu kunentsimbi yekhabhoni ephakathi
I-carbon steel ephezulu luhlobo lwe-carbon steel kunye ne-w (c)> 0.6%.Inomkhwa omkhulu wokuqina kunye nokwenza i-carbon martensite ephezulu kune-carbon steel medium, kwaye ivakalelwa ngakumbi ekubunjweni kweentanda ezibandayo.

Ngelo xesha, isakhiwo se-martensite esakhiwe kwi-HAZ sinempahla enzima kunye ne-brittle, ekhokelela ekunciphiseni kweplastiki kunye nokuqina kokubambisana.Ke ngoko, i-weldability yentsimbi yekhabhoni ephezulu imbi kakhulu, kwaye inkqubo yokuwelda ekhethekileyo kufuneka yamkelwe, ukuqinisekisa ukusebenza kwesinxibelelanisi.
Ke ngoko, kwisakhiwo se-welding, ngokuqhelekileyo kunqabile ukusetyenziswa.Intsimbi yekhabhoni ephezulu isetyenziswa ikakhulu kumacandelo omatshini afuna ubunzima obuphezulu kunye nokumelana nokunxiba, okunje ngeeshafu ezijikelezayo, iigiya ezinkulu kunye nokudibanisa.
Ukuze ugcine intsimbi kunye nokwenza lula iteknoloji yokucubungula, la macandelo omatshini ahlala enziwe ngesakhiwo esidibeneyo.Ekwenziweni koomatshini abanzima, iinxalenye zentsimbi yekhabhoni ephezulu nazo ziya kudibana neengxaki ze-welding.
Xa usenza inkqubo ye-welding yeendawo eziphezulu ze-carbon steel, kuyimfuneko ukuhlalutya zonke iintlobo zeephene ezinokwenzeka ze-welding kwaye uthathe imilinganiselo yenkqubo ye-welding ehambelanayo.
