Simbi isina ngurachinhu chinoshandiswa nevakawanda chinozivikanwa nekunaka kwaro kwekudzivirira uye mashandiro emagetsi. Medium frequency inverter spot welding inopa yakasarudzika mabhenefiti maererano nekurongeka, kutonga, nzvimbo welding ndiyo imwe welding process yeresistance welding, uye welding quality yesimbi isina tsvina. Muchinyorwa chino, isu tichaongorora maitiro uye kufunga kwekupikisa nzvimbo welding simbi isina tsvina.
Kusarudzwa kwezvinhu uye Kugadzirira:Kusarudza iyo chaiyo Stainless simbi zvichibva pane chaiyo application zvinodiwa kwakakosha usati watanga welding process. Simbi isina simbi ine akasiyana alloy zvinhu senge chromium, nickel, uye molybdenum, izvo zvinobatsira mukurora kwayo kuramba uye weldability. Pamusoro pezvo, iyo workpiece yepamusoro inofanirwa kucheneswa zvakanaka uye isina zvinosvibisa kuti ive nechokwadi chemhando yewelding.
Electrode Selection:Sarudzo ye electrode yakakosha kana welding simbi isina tsvina. Inokurudzirwa kushandisa maelectrodes akaitwa kubva kune zvinhu zvinoenderana nesimbi isina tsvina, yakadai sechromium zirconium mhangura kana mhangura alloys. Aya maelectrode anopa yakanaka conductivity yemagetsi uye kugadzikana kwekupisa, kuve nechokwadi chekufambisa kwesimba kunoshanda uye hupenyu hurefu hwemagetsi.
Welding Parameters:Kuti ubudirire weld Stainless simbi, zvakakosha kunyatso kudzora iwo welding paramita. Zvinhu zvakaita sewelding ikozvino, nguva, uye kudzvanywa zvinoda kuvandudzwa zvichienderana negiredhi uye ukobvu hwesimbi isina tsvina. Kazhinji, yakaderera welding ikozvino inofarirwa kudzikisa kupisa kwekuisa uye kudzivirira deformation uku uchivimbisa kusanganisa kwakaringana kwezvinhu. Ukobvu hwakasiyana hwemapuleti esimbi isina simbi dzingada akasiyana welding currents uye nguva. Naizvozvo, iwe unofanirwa kuziva akakodzera welding paramita kune yega yega gobvu resimbi isina tsvina. Pazasi pane tafura yewelding parameters ye spot welding Stainless steel.
| Tkukwira/mm | Electrode muromo dhayamita/mm | Welding ikozvino/A | Welding nguva/s | Electrode pressure/N |
| 0.3 | 3.0 | 3000 ~ 4000 | 0.04~0.06 | 800 ~ 1200 |
| 0.5 | 4.0 | 3500~4500 | 0.06 ~0.08 | 1500 ~ 2000 |
| 0.8 | 5.0 | 5000 ~ 6500 | 0.10 ~ 0.14 | 2400~3600 |

Shielding Gasi:Welding simbi isina tsvina inowanzoda kushandiswa kwekudzivirira gasi kuchengetedza nzvimbo yeweld kubva pakusvibiswa uye kusvibiswa. Chisarudzo chinowanzoitwa musanganiswa we argon uye helium, iyo inopa arc yakagadzikana uye inodzivirira zvinobudirira simbi yakanyungudutswa. Kuyerera kweyero yekudzivirira gasi kunofanirwa kugadziridzwa kuti kuve nechokwadi chekuvhara kwakakwana uye kuchengetedzwa panguva yekugadzira welding.
Welding Technique:Paunenge uchishandisanzvimbo welderyesimbi isina tsvina, iyo chaiyo welding tekinoroji yakakosha. Zvinokurudzirwa kushandisa akatevedzana mapfupi welding pulses pane kuenderera welding kuderedza kupisa kupinza uye kudzora weld dziva. Pamusoro pezvo, kuchengetedza kusimba kunoenderana mukati meiyo welding process kunobatsira kuwana akasimba uye mayunifomu weld majoini.
Post-Weld Treatment:Mushure mekupedza kugadzirwa kwewelding, zvakakosha kuita post-weld treatment kuti uone kuti simbi isina tsvina inosangana nezvinodiwa zvekushanda. Izvi zvinogona kusanganisira maitiro akadai sekupfuura, pickling, kana annealing, zvichienderana negiredhi resimbi isina tsvina uye zvinodiwa pakushandisa. Aya marapirwo anobatsira kudzoreredza corrosion resistance uye kubvisa chero zvingangoita sensitization nyaya dzinokonzerwa newelding process.
Post-Weld Testing:Kuti uone kuti simba re weld rinosangana nemayero anodiwa, kuyedza kunoparadza kana kuomerwa kuyedzwa kunowanzoitwa mushure mekupinza. Kuparadza kuyedzwa nemeso kunotarisa kana iyo weld joint yapinda zvizere mukati meiyo workpiece. Kana chibatanidza chiri nyore kuputsika, weld haina kubudirira. Weld yakabudirira ichabvarura simbi yepasi pasina kutyora mubatanidzwa. Tensile yekuyedza inoyera iyo yakanyanya kusimba simba iyo weld joint inogona kumira, ichipa ongororo yehunyanzvi kuti ione kana inosangana nezvinodiwa zvinoenderana nesimba rinodiwa rekusimba reiyo workpiece.
Medium frequency inverter spot welding inopa nzira inoshanda yewelding simbi isina tsvina, ichipa chaiyo kudzora, kushoma kupisa kwekuisa, uye yakanakisa weld mhando. Nekufunga zvinhu zvakaita sekusarudzwa kwezvinhu, sarudzo ye electrode, welding parameters, shielding gasi, welding technique, uye post-weld treatment, vagadziri vanogona kuwana akavimbika uye akasimba welds mune Stainless simbi application. Iine mabhenefiti ayo epakati, epakati frequency nzvimbo welding michina maturusi akakosha mumaindasitiri senge mota, kuvaka, uye kugadzira chikafu, uko kuramba kutu uye kutendeseka kwemuchina kwakakosha.
Riniiweusea spot welder for Stainless steel welding, zviri pamusoro apa zvinofanirwa kubatsira. Pamusoro pezvo, kusarudza yemhando yepamusoro-stainless simbi spot welder chinhu chakakosha zvakare.
