Flash butt welding inzira inoshandiswa zvakanyanya muindasitiri yewelding yekubatanidza simbi workpieces. Kuve nechokwadi chesimbi dzakasimba uye dzakavimbika welds, zvakakosha kugadzirira maworkpieces nemazvo nekuachenesa pamberi pekuita welding. Muchikamu chino, tichaongorora kukosha kwe pre-weld workpiece yekuchenesa ye flash butt welding machines.
Flash butt welding, inozivikanwawo seresistance butt welding, inosanganisira kujoinha masimbi maviri ekushanda nekugadzira kupisa kuburikidza nekupikisa, zvichikonzera weld yemhando yepamusoro. Kubudirira kweiyi welding process kunoenderana nekuchena kweiyo workpieces inobatanidzwa. Heano zvimwe zvikonzero zvakakosha nei pre-weld workpiece kuchenesa kwakakosha:
- Kubviswa Kwezvinosvibisa: Zvishandiso zvinowanzova nezvinosvibisa zvakaita se ngura, pendi, girisi, uye tsvina pazviso zvavo. Izvi zvinosvibisa zvinogona kukanganisa nzira yewelding nekudzivirira kubatwa kwakakodzera kwemagetsi uye kupisa. Kuchenesa maworkpieces kunovimbisa kuti izvi zvinosvibisa zvinobviswa, zvichibvumira zviri nani weld mhando.
- Enhanced Electrical Conductivity: Yakachena workpieces ine zvirinani magetsi conductivity, izvo zvakakosha kune flash butt welding process. Kana ma workpiece ari kusangana, ikozvino inopfuura nepakati pavo, ichigadzira kupisa panzvimbo yekusangana. Nzvimbo dzakachena dzinogonesa kuyerera kwezvino, zvichikonzera kushanda kwakanyanya uye kudzorwa welding.
- Yakaderedzwa Defects: Welding defects, senge voids, cracks, uye inclusions, zvinowanzoitika kana maworkpiece asina kucheneswa zvakanaka. Nzvimbo dzakachena dzinosimudzira weld ine homogeneous, kuderedza mikana yekukanganisa uku uye kuve nechokwadi chekuti weld yakarongeka.
- Yakavandudzwa Weld Chitarisiko: Yakachena workpieces inotungamira kune yakachena uye inoyevedza inoyevedza weld kutaridzika. Izvi zvinonyanya kukosha mumashandisirwo apo kutaridzika kwemhando ye weld kuri kunetseka, senge mumaindasitiri emotokari kana aerospace.
Maitiro ekuchenesa pre-weld workpiece anowanzo sanganisira kushandiswa kwemaitiro akasiyana-siyana, senge abrasive kuchenesa, kuchenesa makemikari, kana mechanical kuchenesa, zvichienderana nerudzi uye mamiriro ezvishandiso. Sarudzo yekuchenesa nzira inofanira kuitwa tichifunga nezvezvinodiwa zveiyo welding purojekiti.
Mukupedzisa, pre-weld workpiece kuchenesa idanho rakakosha muiyo flash butt welding process. Inochengetedza kubviswa kwezvinosvibisa, inosimudzira conductivity yemagetsi, inoderedza kukanganisa, uye inovandudza huwandu hwese hweweld. Nekudyara mukuchenesa kwakakodzera workpiece, ma welders anogona kuwana akasimba, akavimbika, uye anoyevedza anoyevedza welds, achisangana nepamusoro indasitiri zviyero.
