Yintoni i-weld crack?Sesona siphene sixhaphake kakhulu kwiiweldments.Ngaphantsi kwesenzo esidibeneyo soxinzelelo lwe-welding kunye nezinye izinto ezinqabileyo, amandla okubambisana kwee-athomu zetsimbi kwindawo yendawo ye-welding edibeneyo iyatshatyalaliswa kwaye i-interface entsha yenziwe.Kwitekhnoloji ye-welding, kufuneka sikuphephe ukuqhekeka kwe-welding.
Iintanda ezishushu zeentanda ze-welding:
Iintanda ezishushu ziveliswa phantsi kobushushu obuphezulu, ukusuka kubushushu bokuqina ukuya kubushushu obungaphezulu kwe-A3, ngoko ke zibizwa ngokuba ziintanda ezishushu, ezikwabizwa ngokuba ziintanda eziphezulu.Indlela yokuthintela iintanda ezishushu?Njengoko isizukulwana sokuqhekeka okutshisayo sinxulumene nemiba yoxinzelelo, iindlela zokuthintela kufuneka ziqale kwakhona kwiinkalo ezimbini zokukhethwa kwezinto kunye nenkqubo ye-welding.
Iintanda ezibandayo zeentanda ze-welding:
Iintanda ezibandayo ziveliswa ngexesha okanye emva kokuwelda, kwiqondo lobushushu elisezantsi, malunga nobushushu benguqu ye-martensite (okt point Ms) yentsimbi, okanye kuluhlu lobushushu obungaphantsi kwe-300 ~ 200 ℃ (okanye T ＜ 0.5Tm, Tm yiqondo lokunyibilika ibonakaliswe kubushushu obupheleleyo), ngoko ke zibizwa ngokuba ziintanda ezibandayo.
Phinda utshise iintanda zeentanda ze-welding:
Ukufudumeza kwakhona iintanda kubhekiselele kumalungu adityanisiweyo kwezinye iintsimbi ezisezantsi-zokuqina okuphezulu kunye neentsimbi ezikwazi ukumelana nobushushu eziqulethe i-vanadium, i-chromium, i-molybdenum, i-boron kunye nezinye izinto ze-alloy.Ngexesha lenkqubo yokufudumeza (efana nokunciphisa uxinzelelo, i-multi-layer kunye ne-multipass welding, kunye nomsebenzi wobushushu obuphezulu), iintanda ezenzeka kwindawo erhabaxa yengqolowa yendawo echaphazelekileyo kubushushu kunye nokuqhekeka ecaleni komda wengqolowa ye-austenite ikwabizwa ngokuba luxinzelelo. iintanda annealing (iintanda SR).
Kukho izizathu ezininzi zokuqhekeka kwe-welding, kodwa kungakhathaliseki ukuba yintoni isizathu, ukuba nje iindlela zokuthintela zilawulwa kakuhle, iingozi zokuqhekeka ngexesha le-welding zingancitshiswa kakhulu.
