Uninzi lweziganeko ze-welding deformation zibangelwa yi-asymmetry yobushushu obuveliswa yi-welding kunye nokwandiswa okubangelwa ukushisa okuhlukeneyo. Ngoku siye sahlela iindlela ezininzi zokuthintela ukuguqulwa kwe-welding ngolu hlobo lulandelayo ukuze lubhekiselele:
1. Nciphisa indawo ye-weld ye-weld kwaye usebenzise ubungakanani be-bevel encinci (i-angle kunye ne-gap) kangangoko kunokwenzeka ngelixa ufumana ukugqiba kwaye akukho ziphene ngaphezu komgangatho.
2. Sebenzisa indlela ye-welding ngegalelo elincinci lobushushu. Ezinje: CO2 igesi yokukhusela ukuwelda.
3. Sebenzisa i-welding ye-multi-layer endaweni ye-welding-layer enye nanini na xa kunokwenzeka xa udibanisa iipleyiti ezishinyeneyo.
4. Xa iimfuno zokuyila zidibene, i-welding ye-longitudinal reinforcement ribs kunye ne-transverse reinforcement ribs inokwenziwa nge-welding intermittent.
5.Xa macala omabini anokudityaniswa, kufuneka kusetyenziswe i-bevels ye-symmetrical ephindwe kabini, kunye nokulandelelana kwe-welding ehambelanayo kunye ne-axial components kufuneka isetyenziswe ngexesha le-multi-layer welding.
6. Xa ipleyiti edibeneyo emile okwe-T ijiyile, kusetyenziswa iiwelds ze-bevel angle butt ezivulekileyo.
7. Sebenzisa indlela ye-anti-deformation ngaphambi kwe-welding ukulawula i-angular deformation emva kwe-welding.
8. Sebenzisa isisitho esiqinileyo ukulawula ukuguqulwa kwe-post-weld.
9. Sebenzisa indlela yobude obugciniweyo yecandelo ukuze uhlawule i-longitudinal shrinkage kunye nokuguqulwa kwe-weld. Umzekelo, i-0.5 ~ 0.7 mm inokugcinwa ngemitha ye-H-shaped longitudinal weld.
10. Ngokugqwetha amalungu amade. Ikakhulu ixhomekeke ekuphuculeni i-flatness yebhodi kunye nokuchaneka kwendibano yamacandelo ukwenza i-angle ye-bevel kunye nokukhutshwa ngokuchanekileyo. Isalathiso okanye i-centering ye-arc ichanekile ukwenzela ukuba i-angle ye-weld deformation kunye nexabiso le-longitudinal deformation yephiko kunye newebhu ihambelana nobude becala lecandelo.
11. Xa i-welding okanye ukufakwa kwamacandelo ane-welds engaphezulu, ulandelelwano lwe-welding olufanelekileyo kufuneka lwamkelwe.
12. Xa udibanisa iipleyiti ezincinci, sebenzisa i-welding emanzini. Okokuthi, i-pool etyhidiweyo ijikelezwe yigesi ekhuselayo emanzini, kwaye amanzi asondeleyo asuswe ngokupheleleyo kwigesi ukuze kuqinisekiswe ukuba i-welding yenziwa ngokuqhelekileyo. Ngokusebenzisa le ndlela, isinyithi esijikeleze i-pool yokunyibilika okuqinileyo ipholiswa ngamanzi ngexesha, kwaye isixa se-deformation silawulwa kumlinganiselo omncinci kakhulu (i-coolant ejikelezayo yongezwa ngokuphambene necala le-welding ukususa ubushushu obuveliswa yi-welding).
13. I-Multi-stage symmetrical welding, oko kukuthi, i-welding enye icandelo, yima ixesha elithile, i-welding ukuya kwelinye icala, yima ixesha elithile.
