Basa reKupisa Kupisa muSaw Tip Welding

    Welding tungsten carbide (WC) yakaona matipi ekucheka maturusi inzira yakakosha inopesvedzera zvakanyanya kuita uye hupenyu hurefu hwezvishandiso. Nekudaro, iyo welding process inogona kuunza yakasara kusagadzikana uye kushandura iyo microstructure yezvinhu zvinobatanidzwa. Apa ndipo apo kurapwa kwekupisa kunoita basa rakakosha. Nekunyatsoshandisa nzira dzekurapa kupisa mushure mekugadzira, vagadziri vanogona kusimudzira ma mechanic zvimiro zvemajoini akaiswa, kuve nechokwadi chekushanda kwakakwana pasi pemamiriro ekushanda. Ichi chinyorwa chinoongorora kukosha kwekupisa kupisa mune saw tip welding, maitiro anosanganisirwa, uye mabhenefiti aanopa.

1. Kunzwisisa Kupisa Kurapa

    Kurapa kwekupisa inzira inodzorwa inosanganisira kudziyisa uye kutonhodzwa kwezvinhu kuti uwane zvinodiwa zvemuchina. Muchirevo chewelding, kurapwa kwekupisa kunoshanda kudzoreredza kushushikana kwasara, kunatsiridza kuoma, uye kuwedzera kuoma. Iyo chaiyo yekupisa yekupisa nzira inosarudzwa zvinoenderana nemidziyo inobatanidzwa uye inodiwa maitiro echigadzirwa chekupedzisira.

2. Kukosha kweKupisa Kurapa muWelding

2.1 Residual Stress Relief

    Welding inounza akakosha ekupisa magradients ayo anogona kutungamira kune kwasara kushushikana mukati mejoin yakasungwa uye iyo inopisa-yakakanganiswa nzvimbo (HAZ). Izvi zvinonetsa zvinogona kukonzera kurwa, kutsemuka, kana kutadza nguva isati yakwana kwechikamu chakasungwa panguva yebasa. Kurapa kwekupisa kwakakosha pakubvisa kushushikana uku, kusimudzira kugadzikana kwedimensional, uye kuve nechokwadi chekutendeseka kweiyo welded joint.

2.2 Microstructure Optimization

    Iyo welding process inogona kushandura iyo microstructure yezvose tungsten carbide matipi uye simbi substrate. Kupisa kwakanyanya kunogona kutungamirira kune carbide coarsening, iyo inokanganisa kuoma uye kupfeka kuramba kwemazano. Kurapa kwekupisa kunobvumira kunatswa kweiyo microstructure, kukurudzira kupararira kwakafanana kwecarbides uye kuwedzera kushanda kwese kwemasaha mazano.

2.3 Kuvandudza Mechanical Properties

    Kuburikidza nekurapa kwekupisa, vagadziri vanogona kugadzirisa zvimiro zvemakanika yejoini yakashongedzwa kuti isangane nezvinodiwa zvekushandisa. Maitiro akadai sekudziya uye annealing anogona kuvandudza kuomarara uku uchichengeta kuomarara. Chiyero ichi chakakosha pakuona kuti matipi esaha anogona kumirisana nekushushikana kwakanyanya uye abrasive mamiriro anowanikwa panguva yekucheka maoparesheni.

3. Common Heat Treatment Processes

3.1 Kubvisa Stress

    Kudzoreredza kushushikana inzira yekupisa kupisa iyo inosanganisira kudziyisa iyo welded chikamu kune chaiyo tembiricha, kazhinji pazasi pekupisa kwakanyanya kweiyo base material, uye wozoibvumira kutonhora zvishoma nezvishoma. Maitiro aya anobatsira kudzikisa zvakasara zvinonetsa pasina kunyatso shandura iyo microstructure ye tungsten carbide kana simbi substrate.

3.2 Kupisa

    Kupisa kunowanzoitwa mushure mekudzima kuderedza brittleness. Mune mamiriro etungsten carbide akaona matipi, kudziya kunogona kubatsira kuwana chiyero pakati pekuoma uye kuoma. Chikamu chacho chinopisa kune tembiricha yakafanotemerwa uye yobva yatonhodzwa, zvichibvumira kugovaniswazve kwekabhoni uye kuderedzwa kwekushushikana kwemukati.

3.3 Kuwedzera

    Annealing ndiyo yakawedzera kupisa kupisa maitiro ayo anogona kuiswa kune simbi substrates. Inosanganisira kudziyisa zvinhu kusvika pakupisa kwepamusoro uye wozoitonhorera zvishoma nezvishoma kukurudzira recrystallization. Iyi nzira inonatsiridza ductility uye inoderedza kuoma, zvichiita kuti zvive nyore kugadzira kana kuenderera mberi kugadzirisa iyo welded joint.

4. Mafungiro eKubudirira Kupisa Kurapa

4.1 Kudzora Tembiricha

    Kunyatsogadzirisa tembiricha kunokosha panguva yekupisa kupisa. Kupisa zvakanyanya kunogona kutungamirira kukuchinja kusingadikanwi mu microstructure, nepo kusakwana kupisa kunogona kusagadzirisa zvakakwana kushushikana. Kushandisa epamusoro tembiricha yekutarisa masisitimu anogona kubatsira kuve nechokwadi chekuti nzira yekurapa kupisa inoitwa mukati meiyo yakatarwa paramita.

4.2 Chiyero chekutonhora

    Kutonhora kunotevera kurapwa kwekupisa kunoitawo basa rakakosha pakuona ekupedzisira zvimiro zvejoini yakasungwa. Kukurumidza kutonhora kunogona kukonzera kuwedzera kunetseka, nepo kunonoka kutonhora kunosimudzira kufanana mune microstructure. Vagadziri vanofanira kunyatsosarudza nzira yekutonhodza zvichienderana nemidziyo uye zvinodiwa.

4.3 Kuvimbiswa Kwemhando

    Kuisa matanho ekusimbisa emhando yepamusoro kwakakosha kuti uone kushanda kwemaitiro ekupisa. Nzira dzisiri dzekuparadza (NDT) dzakaita sekuomarara kuyedzwa uye microstructural ongororo, dzinogona kubatsira kuongorora kunaka kweweld uye kushanda kwekurapa kwekupisa.

Mhedziso

    Kurapa kwekupisa inhanho yakakosha muwelding ye tungsten carbide saw matipi, kushanda kudzikisa zvakasara kushushikana, optimize microstructure, uye kuwedzera michina zvivakwa. Nekushandisa nzira dzakakodzera dzekupisa kupisa, vagadziri vanogona kuvandudza zvakanyanya mashandiro uye kusimba kwemidziyo yavo yekucheka. Sezvo iyo hardmetal indasitiri inoenderera mberi ichienderera mberi, kubatanidzwa kweakaomesesa ekurapa kupisa maitiro kucharamba kwakakosha pakugadzira emhando yepamusoro tungsten carbide zvigadzirwa zvinosangana nekuomarara zvinodiwa zvemazuva ano maapplication..
