Welding ye titanium

1. Metallic properties uye welding parameters ye titanium

Titanium ine diki giravhiti (chaiyo giravhiti i4.5), simba rakakwirira, kumira zvakanaka kune yakakwirira uye yakaderera tembiricha, uye yakanakisa kutsemuka kwekusagadzikana uye kushomeka kwekushomeka mune wet chlorine. Iyo mechanic properties uye welding yetitanium ine hukama nekuchena kwetitanium zvinhu. Iyo yakakwirira kuchena, zviri nani kuita. Iyo yakaderera kuchena, kuderera kwakanyanya mupurasitiki uye kuoma, uye zvakanyanya kuipa kwekuita welding. Titanium inoshanda zvakanyanya pamusoro pe300°C uye inotora nyore maatomu ehydrogen, okisijeni nenitrogen pakudziya kwepamusoro, zvichiita kuti zvinhu zvipere. Titanium inotanga kutora hydrogen patembiricha yepamusoro inosvika 300°C, oxygen pa600°C, uye nitrogen pa700°C.

Argon arc welding machines inofanirwa kunge iine yakakwira-frequency arc ignition, yazvino attenuation, gasi kunonoka kudzivirira, uye pulse mudziyo welding waya dzinoda michina zvimiro zvakaenzana nemidziyo yemubereki.
Zvinhu zvechivharo chekudzivirira chinofanira kunge chiri chepepuru simbi kana titanium, uye chimiro chinofanira kunge chakanakira kuchengetedza weld kudzivirira weld kubva pakuchinja ruvara. Stainless simbi waya mesh inofanirwa kuiswa mukati mevhavha yekudzivirira kuti itambe gasi buffering basa.

Xinfa welding midziyo ine hunhu hwemhando yepamusoro uye mutengo wakaderera. Kuti uwane ruzivo, ndapota shanya:Welding & Cutting Manufacturers - China Welding & Cutting Factory & Suppliers (xinfatools.com)

2. Titanium welding operation tekinoroji

Kuchenesa tisati tawelding:
Nyaya yacho yakanyungudutswa nemuchina wekona, uye oxide scale, girisi, burrs, guruva, nezvimwewo mukati me25mm kumativi ose maviri anoputirwa nebhurashi rewaya, uye ozopusika neacetone kana ethanol.

Welding protection:

Usati welding, unofanira kutanga wadzidza argon kudzivirira. Kana uchidzivirira, mumwe munhu anobata chivharo chekudzivirira kuchengetedza rutivi rwepamusoro, uye mumwe munhu anobata chivharo chekudzivirira kuchengetedza rutivi rwezasi. Mudziviriri anofanira kushanda zvakanaka neanopisa. Mushure mekuputika, chivharo chekudzivirira chinogona chete kusunungurwa mushure mokunge weld yatonhora pasi. Kune imwe-sided welding uye kaviri-sided kuumba, kunyanya kukoshesa kunofanira kubhadharwa kune kuchengetedzwa kwemashure kumashure. Kana iyo isina kuchengetedzwa zvakanaka, iyo welding fluid haigone kuyerera, uye hapazove nekuumbwa.
Kana welding, weld inofanirwa kunge iine gap rakakwana re3-5mm kuita gomba rearc. Bata pfuti yewelding muruoko rwako rwerudyi uye edza kudzikisa tungsten electrode ye welding pfuti. Bata waya yewelding neruoko rwako rwekuruboshwe woshandisa chigunwe chako nechigunwe chepakati kusungirira waya yewelding woitumira kumberi. Paunotumira waya welding, unofanirwa kuchengetedza kuenderera uye kugadzikana. Maoko maviri aya anofanira kubatirana zvakanaka kuchengeta weld flat. Maziso anofanirwa kugara achiona kudzika kwedziva rakanyungudutswa uye kuyerera kwemvura yekudziya. Ikozvino inofanira kugadziriswa maererano nemitemo uye yakawandisa ikozvino inorambidzwa.

Iyo muromo we argon gasi inochengetwa pa 5ml, gasi rekudzivirira rinochengetwa pa 25ml, uye kumashure kunochengetwa pa 20ml kuona kuti weld haishanduki ruvara mushure mekuvhara kwekudzivirira. Kana welding kaviri, imwe nguva yekutonhora inofanira kusiiwa kuti ideredze tembiricha yepasi kusvika pazasi 200 ℃, zvikasadaro mitswe uye brittleness zvinozoitika nyore. Flat welding uye nozzle rotation welding inofanira kushandiswa zvakanyanya sezvinobvira.

Paunenge uchiputira, imba yacho inofanira kunge yakaoma uye isina guruva, mhepo yemhepo inofanira kuva isingasviki 2 mamita / sekondi, uye mhepo ine simba inogona kukonzera kusagadzikana kwearc. Paunenge uchiisa welding, edza kushandisa pulse mudziyo kuita weld kunaka.
