Nhungamiro Itsva yeTack Welding Techniques Yakaburitswa

Tack welding inzira yakakosha mune akawanda ekugadzira uye magungano maitiro. Uyezve, nzira iyi inoshandiswa zvakanyanya mumaindasitiri akasiyana-siyana nekuda kwekusiyana-siyana kwayo, kugona kudzikamisa, uye mutengo-kushanda.

Naizvozvo, chinyorwa ichi chichaongorora magadzirirwo ekutakirira, achivhara tsananguro yayo, marudzi akasiyana, pamwe neakanakira nezvayakaipira, kubatsira vaverengi kunyatsonzwisisa iyi nzira yekushongedza.

Chii chinonzi Tack Welding?

A tack weld is temporary weld inoshandiswa kubata zvidimbu zviviri kana kupfuura zvesimbi panzvimbo isati yaita yekupedzisira weld. Iyi nzira inowanzobatanidza kushandiswa kwekupisa kwakadzika uye pfupi welding arc kubatanidza zvikamu zvesimbi pamwechete.

Uyezve, chinangwa chechiitiko ichi ndechekugadzirisa zvimedu zvesimbi zvakanaka pamberi pekuisa. Uye zvakare inodzivirira zvikamu kubva pakufamba kana kushanduka panguva yekugadzira welding. Mune mamwe mazwi, inogona kupa kugadzikana kwakakwana kubvumira welder kuti apedze weld yekupedzisira kubudirira. Nekudaro, welding yenguva pfupi inhanho yakakosha yekutanga mune akawanda welding application.

Tack Welding Inoshanda Sei?

Zvagara zvichizivikanwa kuti iyi welding process inowanzo shandisa arc kugadzirisa zvidimbu zviviri. Saka nekudaro, tack welding inzira iri nyore zvichienzaniswa nemamwe, uye pazasi pane mamwe matanho akajairika.

• Kugadzirira : Izvo zvakakosha kuti unzwisise kudhirowa uye tekinoroji zvinodiwa usati watanga welding. Tevere, zvinodawo kuve nechokwadi chekuti nzvimbo yekubatira inochengetwa yakachena uye isina mamwe maokisi.
• Parameters Kugadziriswa: Anotakurika arc welder seMIG welder uye TIG welder, anowanzo shandiswa mukuita uku. Saizvozvo, welder anogadzirisa welding ikozvino uye voltage kuti ikwane ukobvu uye marudzi ezvishandiso zvewelding.
• Tacking : Kupisa kunopisa kwakagadzirwa nearc welds kunotungamira kune masimbi emagetsi kunyungudika nekukurumidza. Masimbi anobva atonhorera pasi nekukurumidza kana welding yapera. Kazhinji, kureba kwediki diki kunotangira kubva pa½ inches kusvika ¾ inches, uye isingapfuuri 1 inch.

Zvishandiso zvinogona kuve Tack Welded

Kazhinji, ma welders anowanzo shandisa simbi zvinhu mukuita tack welding process. Zvisinei, tinosarudza sei zvinhu zvakakodzera uye zvakakodzera? Zvinhu zvakakosha zvinogara pane kudziya kwechinhu, kukanganiswa nekukanganiswa uye coefficient yekuwedzera kwekupisa. Pazasi pane mamwe masimbi akajairika.

• Carbon Steel
• Simbi isina ngura
• Aluminium
• Aluminium Alloy
• Iron
• Mhangura
• CuCrZr

Mhando dzeTack Welds

Imwe neimwe mhando ye tack weld inoshandira yayo yakasarudzika maapplication uye zvinangwa, uye chikamu ichi chinosuma mamwe marudzi akajairika.

Standard Tack Weld

Iyi mhando ye weld inogona kumira zvinhu zvinorema uye yakabatirira zvakasimba zvidimbu panzvimbo yekupedzisira welding process.

Bridge Tack Weld

Kazhinji, ma welders anowanzo shandisa nzira iyi kana paine gaka diki pakati pezvinhu zviviri zvesimbi mushure mekusangana. Mune mamwe mazwi, nzira iyi inoitirwa kuzadza iwo maburi anokonzerwa nekucheka kusina kunaka kana kukanganisa.

Heano humwe hunyanzvi murudzi urwu rwewelding: kushandisa diki diki pane imwe neimwe chikamu, zvichibvumira nguva yakakwana yekuti vatonhorere pasi.

Hot Tack Weld

Kupisa kunopisa kwakafanana nekukanda bhiriji, sezvo maitiro ese ari maviri anoitirwa kuzadza mapundu. Nekudaro, musiyano wakakosha ndewekuti kupisa kunopisa kunoda kuti welder ashandise sledgehammer kurovera zvidimbu munzvimbo yakakodzera.

Thermit Tack Weld

Thermit welding inzira inoshandisa exothermic kemikari kuita kuburitsa tembiricha yakakwira, inogona kusvika ku4000 degrees Fahrenheit. Mukuwedzera, zvinosanganisirawo musanganiswa wezvinhu, zvakadai sealuminium poda uye iron oxide poda.

Ultrasonic Tack Weld

Ultrasonic welding inosanganisira kushandiswa kwepamusoro-frequency mechanical vibrations kugadzira kupisa uye kusanganisa simbi pamwe chete. Iko kukurumidza kudengenyeka kunogadzira kukweshera pane iyo interface pakati pezvikamu zvesimbi, zvichikonzera kupisa kwenzvimbo nekunyungudika. Mukuita uku, mawelders anogona kusundira zvakananga zvikamu zvakanyungudutswa musimbi yepasi pasina zvimwe zvekuzadza.

Mafomu eTack Weld

Kune mafomu mana e tack weld. Kusarudza fomu rakakodzera kunogona kubatsira kuvandudza welding kunyatsoita uye kunaka. Nokudaro, chikamu chino chichavatsanangura zvakadzama.

Square Tack Weld: Iyi fomu yewelding inopa kubatana kwakasimba nekushandisa mawelds musquare pattern, zvichiita kuti kubatanidzwa kwezvikamu zviviri zvakamira pamakona akarurama.

Vertical Tack Weld: Nzira iyi inosanganisira kuisa vertical tack weld inosvika paurefu hwakazara hwezvidimbu zviviri zviri kubatanidzwa, pane kungoisa nzvimbo yenzvimbo pamusoro.

Right Angle Tack : Iyi mhando ye tack weld inoshandiswa kubatanidza zvidimbu zviviri zvesimbi zviri kusangana pa90-degree angle. Inowanzoshandiswa kuchengetedza pasi zvidimbu zvesimbi mune iyi perpendicular configuration.

Right Angle Corner Tack Weld: Mawelders anowanzo shandisa fomu iri kudzivirira kuumbwa kwechibatanidza chakaita T pakati pezvinhu zvesimbi zveperpendicular.

Zvakanakira uye Zvakaipa zveTack Welding

Tack Welding tekinoroji inoburitsa akati wandei mabhenefiti, asi inosanganisirawo zvimwe zvipimo.

Zvakanakira Tack Weld

• Kugadzirisa Kwenguva: Zvikamu zvesimbi zvinogadziriswa kwenguva pfupi kuti zvifambise nzvimbo yakarurama.
• Kubudirira: Inobatsira kuvandudza kushanda zvakanaka kwekutonga kwayo kuri nyore
• Mutengo Wakaderera: Kuenzaniswa nedzimwe nzira dzewelding, tack welding haina kudhura.
• Wide Application: Inokodzera zvinhu zvakawanda uye inogona kushandiswa kune simbi zvikamu zvehukobvu hwakasiyana.

Cons yeTack Weld

• Simba Rinoganhurirwa: Kugadziriswa kwechinguva hakugone kutsiva simba rekupedzisira rakaitwa zvakanaka weld.
• Distortion: Yakashata tack weld kuiswa kana yakawandisa tack weld saizi inogona kutungamira mukukanganisa.
• Unyanzvi hunodiwa: Kugadzira emhando yepamusoro tack welds kunoda hunyanzvi uye ruzivo kubva kune welder.

Nzira yeKuwana Tack Yakanaka?

Iyo yemhando yepamusoro tack weld inobatsira kuita yakakwana yekupedzisira weld sezvo ichigona kudzivirira zvinhu kubva pakutsemuka kana kudonha pakufamba. Nekudaro, chikamu ichi chinokupa iwe matipi akazara ekuwana yakanaka tack weld.

• Chengetedza waya yesimbi yakachena, uye sarudza waya ine dhayamita diki.
• Ita shuwa kuti bapi rekubata harina kupfeka.
• Shandisa matepi kuchengetedza zvinhu zvakagadziriswa.
• Ita shuwa kuti huwandu hwema tack welds hunoenderana nehukuru hweweld.
• Ronga kurongeka uye kutungamira kwewelds.
• Shandisa voltage yakasimudzwa uchiichengeta yakatsiga.

Tack Welding vs. Spot Welding

Kunyangwe aya maviri welding akafanana, anewo mimwe misiyano. Uye misiyano mikuru pakati petack welding uye spot welding ndeiyi:

• Tack weld inzira yenguva pfupi yewelding inoshandiswa kubata mativi panzvimbo, ukuwo spot welding inzira yekupokana inogadzira iyo inogadzika, yakatenderedzwa weld.
• Tack welds idiki uye haina kudzika, nepo spot welds yakasimba uye yakasimba.
• Tack welding inowanzo shandiswa kuungana uye kurongeka, nepo spot welding iri mukugadzirwa kwehuwandu

  Mhedziso

  Kunzwisisa kuomarara kwetack welding kwakakosha kune chero welder, mainjiniya, kana mugadziri wekugadzira ari kutarisa kukwenenzvera maitirwo ewelding uye kuunza mhedzisiro yemhando yepamusoro.

  Uyezve,HUAYI GROUP ine hunyanzvi hwakakura mu tekinoroji welding. Isu tiri nyanzvi mune tsikaCNC machining masevhisi, kubva pakugadzira uye kukurumidza prototyping kusvika yakaderera kana yakakwirira-vhoriyamu kugadzirwa kwezvikamu zvakaoma. Naizvozvo, isu tinogona kusangana neyako chaiyo welding zvinodiwa. Inzwa wakasununguka kutibata nesu kune mapurojekiti ako kanakumbira mhinduro pakarepo.
