Titanium muaj qhov sib nqus tshwj xeeb me me (qhov tshwj xeeb lub ntiajteb txawj nqus yog 4.5), lub zog siab, ua haujlwm zoo rau qhov kub thiab txias, thiab zoo heev tawg tiv thaiv thiab corrosion kuj nyob rau hauv ntub chlorine. Cov khoom siv kho tshuab thiab vuam ntawm titanium muaj feem xyuam rau kev purity ntawm titanium cov ntaub ntawv. Qhov siab dua qhov purity, qhov ua tau zoo dua. Qhov qis dua qhov purity, qhov poob qis hauv plasticity thiab toughness, thiab qhov ua tau zoo dua qhov vuam vuam.
1. Cov khoom siv hlau thiab vuam tsis zoo ntawm titanium
Titanium muaj zog heev tshaj 300 degree thiab yooj yim absorbs hydrogen, oxygen, thiab nitrogen atoms ntawm kub, ua rau cov khoom nkig. Titanium pib nqus hydrogen ntawm qhov kub ntawm 300 degree, oxygen ntawm 600 degree, thiab nitrogen ntawm 700 degree.
Lub argon arc vuam tshuab yuav tsum muaj high-frequency arc pib, tam sim no attenuation, thiab roj ncua kev tiv thaiv, thiab cov mem tes vuam hlau yuav tsum tau txhua yam khoom sib npaug rau cov khoom niam txiv.
Cov khoom siv ntawm kev tiv thaiv npog yuav tsum yog xim liab lossis titanium, thiab cov duab yuav tsum yooj yim rau kev tiv thaiv cov vuam kom ua tiav qhov vuam yam tsis muaj xim. Lub stainless hlau xaim mesh yuav tsum tau muab tso rau hauv lub npog tiv thaiv kom ua lub luag haujlwm ntawm cov pa roj.
2. Titanium vuam tshuab ua haujlwm
Ntxuav ua ntej welding:
Siv lub tshuab beveling los ua ib qho zawj rau cov khoom siv, siv cov txhuam hlau los txhuam cov oxide nplai, roj, burrs, plua plav, thiab lwm yam hauv 25 hli ntawm ob sab thiab tom qab ntawd so nrog acetone lossis ethanol.
Vuam tiv thaiv:
Ua ntej vuam, koj yuav tsum xub kawm txog kev tiv thaiv argon. Thaum lub sij hawm tiv thaiv, ib tug neeg tuav daim ntaub thaiv npog tiv thaiv sab sauv, thiab lwm tus neeg tuav daim ntaub thaiv kom tiv thaiv qhov qis. Tus tiv thaiv yuav tsum koom tes zoo nrog tus welder. Tom qab vuam, koj yuav tsum tau tos kom txog thaum lub vuam txias ua ntej koj tuaj yeem loosen daim ntaub thaiv. Rau kev sib txuas ib leeg thiab ob sab sib sau ua ke, xyuam xim tshwj xeeb rau kev tiv thaiv sab nraub qaum. Yog tias nws tsis muaj kev tiv thaiv zoo, cov kua welding tsis tuaj yeem ntws thiab yuav tsis muaj kev sib sau.
Thaum vuam, qhov vuam yuav tsum muaj qhov sib txawv txaus ntawm 3-5mm los ua ib lub qhov arc. Tuav rab phom vuam ntawm koj sab tes xis thiab sim txo cov tungsten electrode ntawm rab phom vuam. Tuav lub vuam hlau ntawm koj sab tes laug thiab siv koj tus ntiv tes xoo thiab ntiv tes nruab nrab los tuav lub vuam hlau thiab pub rau pem hauv ntej. Thaum pub cov vuam hlau, koj yuav tsum muaj kev ruaj khov thiab ruaj khov. Ob txhais tes yuav tsum sib koom tes zoo kom lub vuam tiaj tus. Lub qhov muag yuav tsum nco ntsoov saib qhov tob ntawm lub pas dej molten thiab qhov ntws ntawm cov welding kua. Qhov tam sim no yuav tsum tau hloov kho raws li cov kev cai thiab tsis pub dhau tam sim no.
Lub nozzle argon roj yog khaws cia ntawm 5ml, cov roj shielding yog khaws cia ntawm 25ml, thiab sab nraub qaum yog khaws cia ntawm 20ml kom ntseeg tau tias cov vuam tsis hloov xim tom qab lub hau npog. Thaum vuam ob zaug, qee lub sijhawm txias yuav tsum tau sab laug kom txo qhov kub ntawm qhov chaw kom qis dua 200 degree, txwv tsis pub, tawg thiab brittleness yuav yooj yim tshwm sim. Lub tiaj vuam thiab lub tshuab nozzle tig vuam yuav tsum tau siv ntau li ntau tau.
Thaum vuam, chav tsev yuav tsum qhuav thiab tsis muaj plua plav, cua ceev yuav tsum tsawg tshaj li 2 meters / thib ob, thiab cua muaj zog tuaj yeem ua rau cov arcs tsis ruaj khov. Thaum capping welding, sim siv cov khoom siv mem tes ua kom lub vuam zoo nkauj.
3. Kev tsim cov txheej txheem thiab kev siv thev naus laus zis ntawm cov khoom siv titanium
Cov ntaub ntawv siv rau kev ua cov titanium raj, titanium luj tshib, thiab titanium tso tsheb hlau luam yuav tsum ua tau raws li qhov yuav tsum tau ua. Lawv toughness, lub zog, thiab elasticity yuav tsum muaj daim ntawv pov thawj phaj. Txhua lub phaj titanium yuav tsum tau kho nrog tus pas ntsuas. Qhov loj me yuav tsum raug xam thaum txiav cov ntaub ntawv kom tsis txhob muaj cov khoom seem ntau dhau. Lub tshuab shearing yuav tsum tau siv thaum txiav daim hlau, thiab cov roj txiav yuav tsum zam kom ntau li ntau tau. Cov kab yuav tsum tau qhia meej meej thiab raug cim thaum siv cov kav dej. Kev siv cov pa roj rov qab raug txwv nruj heev. Tom qab txiav lub phaj, lub tshuab chamfering yog siv los ua ib qho zawj. Qhov zawj yuav tsum yog uniform. Tom qab lub phaj yog dov los ntawm lub phaj dov tshuab thawj zaug, lub vuam yuav tsum yog me ntsis concave los pab txhawb qhov thib ob shaping tom qab vuam.
Muaj qhov sib txawv loj ntawm kev saib xyuas thiab kev ua haujlwm ntawm titanium daim hlau. Cov yam tseem ceeb muaj xws li ib puag ncig, kev hloov khoom siv, thiab lwm yam. Lub vuam yuav tsum raug tiv thaiv yog tias nws tuaj yeem tiv thaiv. Yog tias nws tsis tuaj yeem tiv thaiv ob sab, siv me me tam sim no tiv thaiv ib leeg. Tom qab lub weld tawg, tsis txhob welded ntawm thawj weld. Vuam yuav tsum tau ua los ntawm patching lub phaj. Thaum qhov chaw vuam yog cua, yuav tsum muaj cua ntsawj ntshab, thiab lub tarpaulin lossis hlau phaj yuav tsum tau siv los tiv thaiv. Thaum noj cov yeeb nkab, yuav tsum muaj qhov sib txawv lossis staggered vuam vim tias sab hauv tsis tuaj yeem tiv thaiv. Lub weld yuav tsum tsim nyog widened thiab thickened.
