Iindaba - Irobhothi yeYooheart ixela izaziso ze-welding yegesi ekhuselayo

I-gas shielded welding ibhekisela kwindlela ye-welding ekhuselwe yi-carbon dioxide okanye i-argon, ngaphandle kokusebenzisa ucingo lwe-welding. Inkqubo ye-welding ye-gas shielded welding ilungele ukudityaniswa kweeprojekthi ezahlukeneyo zesakhiwo sentsimbi ezifana ne-low-carbon steel kunye ne-alloy low-alloy high-strength steel. Inokuvelisa okuphezulu kwe-welding, ukumelana nokuqhekeka okulungileyo, i-welding deformation encinci, kunye noluhlu olukhulu lokuguqulwa. Ukuwelda kweepleyiti ezincinci kunye neepleyiti eziphakathi kunye nezityebileyo zinokwenzeka.

Iindlela ezahlukeneyo zokuwelda ze-welding yegesi ekhuselweyo

1. ukuwelda ngokuthe nkqo

Isikhundla setotshi ye-welding ibaluleke kakhulu xa udibanisa ngokuthe nkqo, kwaye itotshi ye-welding kufuneka ibe yi-perpendicular kwi-workpiece. Ngexesha le-welding ye-straight-line, i-weld bead ithande ukuba yi-convex, kwaye ukubonakala kwe-weld bead kubi kwaye kulula ukunqumla.

Ngexesha le-welding ye-multi-layer, i-bead yokuzalisa ngasemva kulula ukuba ingabonakali kwi-welding, ngoko ayisetyenziswanga ngokubanzi. Ke ngoko, ukuwelda ukuya phezulu ngokuthe nkqo kudla ngokujinga, kwaye indlela yokujingi yinto encinci. Ekubeni ubushushu bugxininiswe ngeli xesha, i-weld bead ilula ukukhupha, ngoko kufuneka ihambe ngokukhawuleza phantsi kwemeko ye-uniform swing.

Ukuba kufuneka umlenze wokuwelda omkhulu, indlela yokujingisisa icrescent kufuneka isetyenziswe ukuhamba ngokukhawuleza embindini we weld bead kwaye uhlale kancinci kumacala omabini ukuthintela undercut. Nangona kunjalo, kufuneka kuthathelwe ingqalelo ukuba ungasebenzisi ujingi olugobileyo olujonge ezantsi.

2. ukuwelda nkqo phantsi

Kwiwelding esezantsi ethe nkqo, ukuze kugcinwe idama elinyibilikisiweyo, itotshi yokuwelda kufuneka ikhombe ngezantsi kwidama elityhidiweyo kwaye igcine i-engile ethile. I-arc kufuneka ihlale ijoliswe ngaphambili kwi-pool etyhidiweyo, ngaphandle koko, xa intsimbi etyhidiweyo igeleza phambi kwe-arc, kulula ukubangela amaqhuma e-welding kunye nokungangeni. I-pool metal yanyuswa phezulu.

Iimbangela ze-porosity kwi-welding ekhuselekileyo yegesi

Irhasi yokukhusela embi

1. Umgangatho wegesi kwi-cylinder yegesi ayilungile, kwaye ayinayo ubunyulu obungaphezu kwe-98%. Iqulethe iigesi ezinobungozi ezifana ne-nitrogen, ezibangela iipores emva kwe-welding.

2. Umbhobho wegesi ukusuka kwi-cylinder yegesi ukuya kwitotshi ye-welding ayiqinile, kwaye umoya ungeniswa ukuvelisa iipores.

3. Isiphithiphithi somoya sivelisa i-stomata

a. Umoya kwindawo yangaphandle uphazamisa ukuhamba komoya okhuselayo ojikeleze ichibi elinyibilikisiweyo

b. Ukuhamba kwegesi ephantsi okanye i-splatter evala umlomo

c. I-angle yetotshi ye-welding inkulu kakhulu okanye itotshi ye-welding ikude kakhulu kwi-workpiece

d. Iringi ye-gas shunt ceramic yesikhokhelo sombhobho wetotshi yonakele kwaye ayikasuswa okanye ibuyiselwe

4. Ivalve yomoya yokulawula umatshini wokuwelda ivula i-lag, ivale kwangoko, okanye inxibelelana kakubi ngamaxesha athile

Iziphene kwi-welding wire kunye nesiseko sentsimbi ngokwayo

1. I-core welding wire i-rusted, i-oyile, njl.

2. I-powder yangaphakathi ye-flux-cored welding wire imanzi, kwaye ingaphandle iyagqwala.

3. Kukho ama-pores kwisiseko sesinyithi ngokwawo, okanye kukho ukungcoliseka kweoli eninzi ngaphakathi, okanye ukuguqulwa komgangatho wetsimbi okubangelwa ukusetyenziswa kwexesha elide kwiindawo zeekhemikhali, njengemibhobho yeekhemikhali, isixhobo somatshini esinentsimbi kunye neengxenye zetsimbi.

4. Kukho izinto ezingcolileyo okanye amanzi avelisa iigesi ezinobungozi kwindawo ye-welding, kwaye azicocwanga.

Iiparamitha ze-welding ezingenangqiqo

Ukuba ukulungelelaniswa kwangoku kunye nombane kukhulu kakhulu, kulula ukubola i-carbon dioxide kwi-carbon monoxide kwindawo yokushisa ephezulu kunye ne-ionization ephezulu xa igalelo lobushushu likhulu, kwaye i-carbon monoxide pores iya kuveliswa xa i-weldment ipholile ngokukhawuleza.

Ingcebiso yesisombululo

1. Yongeza i-argon okanye i-carbon dioxide gas exutywe ukuvavanya ukuba i-carbon dioxide gas ayihlambulukanga, kwaye uqaphele ukuba i-gas edibeneyo inefuthe elingcono lokukhusela. Ukuba ewe, tshintsha iyunithi yokubonelela ngegesi enomgangatho olungileyo.

2. Ngaphantsi kokukhuselwa kwegesi edibeneyo, kusekho ama-pores ukuphelisa imbangela yegesi, kunye nezinye izizathu zinokujongwa ngokubonakalayo.

3. Kungcono ukuba ungayihoyi iingxaki zesiseko sesinyithi kunye ne-welding wire ngokwayo.
