1. Iimpawu zetsimbi kunye neeparitha ze-welding ze-titanium
I-Titanium inomxhuzulane okhethekileyo (umxhuzulane okhethekileyo yi-4.5), amandla aphezulu, ukuxhathisa okulungileyo kumaqondo obushushu aphezulu naphantsi, kunye nokumelana nokuqhekeka okugqwesileyo kunye nokumelana nokubola kwiklorini emanzi. Iimpawu zomatshini kunye ne-welding ye-titanium zihambelana nokucoceka kwezinto ze-titanium. Ukuphakama kobunyulu, ngcono ukusebenza. Ukunciphisa ubunyulu, ukuhla ngokukhawuleza kweplastiki kunye nokuqina, kunye nokusebenza kakubi kwe-welding. I-Titanium isebenza kakhulu ngaphezu kwe-300 ° C kwaye ifunxa lula i-hydrogen, i-oksijini kunye ne-athomu ye-nitrogen kumaqondo obushushu aphezulu, yenze i-material brittle. I-Titanium iqalisa ukufunxa i-hydrogen kubushushu obuphezulu obungama-300°C, ioksijini kuma-600°C, kunye ne-nitrogen kuma-700°C.
Oomatshini be-arc welding kufuneka babe ne-high-frequency arc ignition, i-attenuation yangoku, ukhuseleko lokulibaziseka kwegesi, kunye neengcingo ze-welding ze-pulse zifuna iimpawu zoomatshini ezilingana nezinto zomzali.
Izinto eziphathekayo zokukhusela kufuneka zibe yintsimbi emfusa okanye i-titanium, kwaye imilo kufuneka ilungele ukukhusela i-weld ukukhusela i-weld ekutshintsheni umbala. Umnatha wocingo lwentsimbi engenastainless kufuneka ufakwe ngaphakathi kwesigqubuthelo sokhuselo ukuze udlale indima yesithinteli segesi.
Izixhobo zokuwelda iXinfa zineempawu zomgangatho ophezulu kunye nexabiso eliphantsi. Ngeenkcukacha, nceda undwendwele:Abavelisi beWelding & Cutting-China Welding & Cutting Factory & Suppliers (xinfatools.com)
2. Itekhnoloji yokusebenza kwe-Titanium welding
Ukucoca phambi kwe-welding:
Izinto eziphathekayo zihlanjululwe ngomatshini we-angle rolling, kunye nomlinganiselo we-oxide, igrisi, i-burrs, uthuli, njl. ngaphakathi kwe-25mm kumacala omabini ahlanjululwe nge-brush yocingo, aze asule nge-acetone okanye i-ethanol.
Ukhuseleko lokuwelda:
Ngaphambi kwe-welding, kufuneka uqale ufunde ukukhuselwa kwe-argon. Xa ukhusela, omnye umntu ubamba isikhuselo sokukhusela ukukhusela icala eliphezulu, kwaye omnye umntu ubambe isikhuselo sokukhusela ukukhusela icala elingaphantsi. Umkhuseli kufuneka asebenzisane kakuhle ne-welder. Emva kwe-welding, isigqubuthelo sokukhusela sinokukhutshwa kuphela emva kokuba i-weld ipholile. Kwi-welding yecala elilodwa kunye nokubunjwa kwamacala amabini, ingqalelo ekhethekileyo kufuneka ihlawulwe ekukhuselweni kwecala elingasemva. Ukuba ayikhuselwanga kakuhle, i-welding liquid ayinakuhamba, kwaye akuyi kubakho ukwenza.
Xa welding, i-weld kufuneka ibe nesithuba esaneleyo se-3-5mm ukwenza i-arc pit. Bamba umpu we-welding esandleni sakho sokunene kwaye uzame ukuthoba i-electrode ye-tungsten ye-welding gun. Bamba ucingo lwe welding esandleni sakho sasekhohlo kwaye usebenzise ubhontsi wakho kunye nomnwe ophakathi ukucinezela ucingo lwe welding kwaye uluthumele phambili. Xa uthumela i-welding wire, kufuneka ugcine ukuqhubeka nokuzinza. Izandla zombini kufuneka zisebenzisane kakuhle ukugcina i-weld flat. Amehlo kufuneka ahlale eqwalasela ubunzulu bedama elityhidiweyo kunye nokuhamba kolwelo lwe-welding. Umbane kufuneka ulungelelaniswe ngokwemigaqo kwaye ukugqithisa ngokugqithisileyo akuvumelekanga.
Irhasi ye-argon yombhobho igcinwe kwi-5ml, igesi ekhuselayo igcinwe kwi-25ml, kwaye umva ugcinwe kwi-20ml ukuqinisekisa ukuba i-weld ayitshintshi umbala emva kokhuselo lokukhusela. Xa ukuwelda kabini, ixesha elithile lokupholisa kufuneka lishiywe ukunciphisa ubushushu bomhlaba ukuya ngaphantsi kwe-200 ℃, kungenjalo iintanda kunye nokuqhekeka kuyakwenzeka ngokulula. I-flat welding kunye ne-nozzle rotation welding kufuneka isetyenziswe kangangoko kunokwenzeka.
Xa i-welding, igumbi kufuneka lome kwaye lingabikho uthuli, isantya somoya kufuneka sibe ngaphantsi kweemitha ezi-2 / isibini, kwaye umoya onamandla unokubangela ukungazinzi kwe-arc. Xa ufaka i-welding, zama ukusebenzisa isixhobo se-pulse ukwenza i-weld ibe ntle.
3. Inkqubo yokuvelisa kunye nokugcinwa kweteknoloji yezixhobo ze-titanium
Izinto ezisetyenziselwa ukusetyenzwa kweetyhubhu ze-titanium, i-titanium elbows, kunye neitanki ze-titanium kufuneka zihlangabezane neemfuno. Ukuqina kwabo, ukomelela, kunye nokunwebeka kwabo kufuneka kube nesatifikethi sepleyiti. Ipleyiti nganye yetitanium kufuneka ilungiswe ngerula. Ubungakanani kufuneka bubalwe xa usika izinto zokuthintela iziqwenga ezigqithisileyo. Kufuneka kusetyenziswe oomatshini bokucheba xa kusikwa iipleyiti, kwaye ukusika igesi kufuneka kuphetshwe kangangoko kunokwenzeka. Imigca kufuneka imakishwe ngokucacileyo nangokuchanekileyo xa usebenzisa imibhobho. Ukusetyenziswa ngokuphindaphindiweyo kwegesi yokusika kunqatshelwe ngokungqongqo. Emva kokusika ipleyiti, umatshini wokuhlamba kufuneka usetyenziswe ukwenza i-groove. Iintanda kufuneka zifane. Emva kokuba ipleyiti iqengqeleke ngumatshini wokuqengqeleka kwepleyiti okwesihlandlo sokuqala, i-weld kufuneka ibe yiconcave kancinane ukuququzelela ukubunjwa kwesibini emva kwewelding. Ngenxa yokuba ixabiso lezinto ze-titanium liphezulu (malunga ne-140 yuan / Kg kwizinto eziluhlaza kunye ne-400 yuan / Kg emva kokucubungula), inkunkuma kufuneka igwenywe.
Kukho umahluko omkhulu phakathi kokugcinwa nokulungiswa kweepleyiti zetitanium. Izinto eziphambili ziquka izinto zokusingqongileyo, utshintsho lwezinto eziphathekayo, njl njl. I-weld kufuneka ikhuselwe ukuba inokukhuselwa. Ukuba ngenene akunakwenzeka ukukhusela amacala omabini, sebenzisa ukhuselo olukhoyo olukwicala elinye. Emva kokuqhekeka kwe-weld, musa ukuyifaka kwi-weld yokuqala. I-Welding kufuneka yenziwe ngokudibanisa ipleyiti. Xa indawo yokudibanisa i-welding inomoya, kufuneka kubekho indawo yokukhusela umoya, kwaye i-tarpaulin okanye i-iron plate kufuneka isetyenziswe ukukhusela. Xa uthatha umbhobho, kufuneka kubekho i-gap okanye i-welding edibeneyo kuba ngaphakathi ayikwazi ukukhuselwa. I-weld kufuneka yandiswe ngokufanelekileyo kwaye yandiswe.
