Izinto ezinobungozi zezinto ze-welding
(1) Eyona nto iphambili yophando ye-welding ucoceko lwabasebenzi yi-fusion welding, kwaye phakathi kwabo, iingxaki zococeko lwabasebenzi be-open arc welding zezona zikhulu, kwaye iingxaki ze-arc welding kunye ne-electroslag welding zincinci.
(2) Izinto eziphambili ezinobungozi ze-electrode manual arc welding, i-carbon arc gouging kunye ne-CO2 ye-gas shielded welding yi-fume kunye nothuli oluveliswa ngexesha lenkqubo ye-welding - i-welding fume. Ingakumbi i-electrode manual arc welding. Kwaye i-carbon arc gouging, ukuba umsebenzi we-welding wenziwa kwindawo encinci yokusebenza (i-boiler, i-cabin yenqanawa, isitya esingangeni moya kunye nombhobho, njl. njl.) ixesha elide, kwaye kwimeko yokukhusela ucoceko olubi, kuya kubangela ingozi inkqubo yokuphefumla, njl.
(3) Irhasi enetyhefu yeyona nto iyingozi kakhulu kwi-welding yombane yegesi kunye ne-plasma arc welding, kwaye xa ugxininiso luphezulu kakhulu, luya kubangela iimpawu zetyhefu. Ngokukodwa, i-ozone kunye ne-nitrogen oxides ziveliswa yi-arc yobushushu obuphezulu bemitha esebenza kwi-oxygen kunye ne-nitrogen emoyeni.
(4) I-radiation ye-arc yinto eqhelekileyo eyingozi kuyo yonke i-arc welding evulekileyo, kunye nesifo se-electro-optic eye esibangelwa sisifo esikhethekileyo somsebenzi we-open arc welding. Imitha ye-arc inokonakalisa ulusu, ibangela ukuba i-welders ihlupheke kwizifo zolusu ezifana ne-dermatitis, i-erythema kunye namadyunguza amancinci. Ukongezelela, iintambo zekotoni zonakaliswe.
(5) I-tungsten argon arc welding kunye ne-plasma arc welding, kuba umatshini we-welding uxhotyiswe nge-oscillator ephezulu-frequency ukunceda ukuqala i-arc, kukho izinto ezinobungozi - i-high-frequency field electromagnetic field, ngokukodwa umatshini we-welding kunye nexesha elide lokusebenza. ye-oscillator ye-high-frequency oscillator (efana noomatshini bokuwelda be-argon be-argon). Amasimi e-electromagnetic aphezulu anokubangela ukuba abashiseli babandezeleke zizifo zenkqubo yemithambo-luvo kunye nenkqubo yegazi.
Ngenxa yokusetyenziswa kwe-electrode ye-thoriated tungsten rod, i-thorium yinto e-radioactive, ngoko ke kukho izinto ezinobungozi zemitha ye-radiation (α, β kunye ne-γ imitha), kwaye inokubangela iingozi ze-radioactive malunga ne-grinder apho intonga ye-tungsten egciniweyo igcinwa kwaye ilolwe. .
(6) Ngexesha le-plasma ye-arc welding, ukutshiza kunye nokusika, ingxolo enamandla iya kuveliswa, eya konakalisa i-nerve ye-welder ye-auditory ukuba ukukhuselwa akulungile.

Izilumkiso zokusebenzisa izinto ze-welding
1. Ngokuqhelekileyo kukho iindidi ezimbini ze-electrode zensimbi ezingenasici: uhlobo lwe-titanium-calcium kunye nohlobo oluphantsi lwe-hydrogen. I-welding yangoku ithatha unikezelo lwamandla e-DC kangangoko kunokwenzeka, okuluncedo ukoyisa ububomvu kunye nokungena okunzulu kwentonga ye-welding. I-Electrodes ene-titanium-calcium coating ayifanelekanga kwi-welding yonke indawo, kodwa kuphela i-flat welding kunye ne-flat fillet welding; i-electrodes ene-low-hydrogen coating ingasetyenziselwa yonke indawo ye-welding.
2. I-electrodes yensimbi engenasici kufuneka igcinwe yomile ngexesha lokusetyenziswa. Ukuze kuthintelwe iziphene ezifana neentanda, imingxuma, kunye nemingxuma, uhlobo lwe-titanium-calcium ukutyabeka yomiswa kwi-150-250 °C ngeyure enye phambi kwe-welding, kwaye uhlobo oluphantsi lwe-hydrogen luyomiswa kwi-200-300 ° C. Iyure eyi-1 ngaphambi kwe-welding. Musa ukomisa ngokuphindaphindiweyo, ngaphandle koko ulusu luya kuwa lula.
3. Ukucoca i-welding joint, kwaye uthintele intonga ye-welding ukuba ifakwe ngeoli kunye nolunye ukungcola, ukuze unganyusi umxholo wekhabhoni we-weld kwaye uthintele umgangatho we-welding.
4. Ukuze kuthintelwe ukubola kwe-intergranular okubangelwa ukushisa, i-welding current ayifanele ibe mkhulu kakhulu, ngokuqhelekileyo malunga ne-20% ephantsi kune-carbon steel electrodes, i-arc ayifanele ibe yinde kakhulu, kwaye i-interlayers ipholile ngokukhawuleza.
5. Nika ingqalelo xa uqala i-arc, ungaqalisi i-arc kwi-non-welding part, kungcono ukusebenzisa i-arc yokuqalisa iplate yezinto ezifanayo kunye ne-weldment ukuqala i-arc.
6. I-short-arc welding kufuneka isetyenziswe kangangoko kunokwenzeka. Ubude be-arc ngokuqhelekileyo yi-2-3mm. Ukuba i-arc inde kakhulu, ukuqhekeka kwe-thermal kuya kwenzeka ngokulula.
7. Umcu wezothutho: i-short-arc fast welding kufuneka yamkelwe, kwaye i-lateral swing ayivumelekanga ngokubanzi. Injongo kukunciphisa ubushushu kunye nobubanzi bendawo echatshazelwe bubushushu, ukuphucula ukuxhathisa kwe-weld kwi-corrosion ye-intergranular kunye nokunciphisa ukuthambekela kokuqhekeka kwe-thermal.
8. I-Welding of steels dissimilar kufuneka ikhethe ngokucophelela i-welding rods ukukhusela ukuchithwa kwe-thermal ekukhethweni okungafanelekanga kweentonga ze-welding okanye imvula yesigaba se-σ emva kokunyanga kobushushu obuphezulu, okuya kwenza ukuba isinyithi sifakwe. Bhekisela kwimigangatho yokukhetha intonga ye-welding yensimbi engenasici kunye nentsimbi engafaniyo yokukhethwa, kwaye yamkele iinkqubo ezifanelekileyo ze-welding.
