Projection welding inzira inoshandiswa zvakanyanya mumaindasitiri akasiyana ekubatanidza masimbi. Iyo welding process inosanganisira kushandisa kumanikidza uye magetsi emagetsi kugadzira chisungo chakasimba pakati pezvikamu. Imwe yakakosha parameter mukufungidzira welding inguva yewelding, iyo inogona kukanganisa zvakanyanya kunaka kweweld. Ichi chinyorwa chinoongorora mhedzisiro yenguva yewelding pane iyo projection welding basa repakati frequency spot welders.
Nhanganyaya: Projection welding, subtype ye resistance welding, inobatanidza kuumbwa kwewelds panzvimbo dzakatarwa panzvimbo dzesimbi uko kunenge kuine mapurojekiti kana embossments. Aya mafungidziro anonangana neazvino uye kudzvanywa, zvichikonzera kupisa kwenzvimbo uye fusion. Medium frequency spot welders anowanzo shandiswa nekuda kwekushanda kwavo uye kuita zvakasiyana. Iyo nguva yewelding, inotsanangurwa senguva iyo ikozvino inoyerera kuburikidza neweld, chinhu chakakosha pakuwana anowirirana uye akasimba welds.
Mhedzisiro yeWelding Nguva paWeld Hunhu: Iyo nguva yewelding ine simba rakadzama pamhando yekufungidzira welds. Kusakwana welding nguva inogona kutungamirira mukusangana kusina kukwana, zvichiita kuti majoini asina simba. Kune rimwe divi, yakawandisa welding nguva inogona kukonzera kuwandisa, zvichitungamira ku deformation uye kunyangwe kupisa-kuburikidza nezvikamu. Izvo zvakakosha kuti uone iyo yakakwana yewelding nguva inoenzanisa izvi zvinhu kuti uwane yakasimba, yakavimbika welds.
Nzvimbo Inobatwa Nekupisa (HAZ): Nguva yewelding inobata zvakananga saizi yenzvimbo inobatwa nekupisa (HAZ). Iyo ipfupi welding nguva inoderedza kupisa kwekuisa, kuderedza kuwanda kwekupisa kwekupisa mune zvakatenderedza zvinhu. Sezvineiwo, nguva refu yewelding inowedzera iyo HAZ, inogona kukanganisa zvinhu zvemukati uye kurongeka kwekubatana. Saka, kusarudza nguva yakakodzera yewelding kwakakosha pakudzora iyo HAZ uye kuchengetedza yaunoda ma mechanical properties.
Kubudirira Kwekuita uye Kupfuura: Kuwana chiyero chakakodzera pakati penguva yewelding, weld mhando, uye mashandiro ekuita kwakakosha. Kurebesa welding nguva kunogona kutungamira kunonoka mitengo yekugadzira, nepo nguva pfupi inogona kukonzera kukanganisa. Vagadziri vanofanirwa kukwidziridza welding maparamendi kuti ave nechokwadi chemhando yepamusoro welds pasina kukanganisa kugadzirwa kwekugadzira.
Yekuedza Maitiro: Kuti uone iyo yakakwana nguva yekushongedza, zvidzidzo zvekuyedza zvinogona kuitwa. Nguva dzakasiyana dzewelding dzinogona kuyedzwa uchichengeta mamwe ma parameter achigara. Iyo inokonzeresa weld mhando, simba remuchina, uye zviyero zveHAZ zvinogona kuongororwa. Tekinoroji dzechizvino-zvino senge dzisiri-kuparadza kuyedza uye metallurgical ongororo inogona kupa kukosha kwakakosha mune weld maitiro.
Munzvimbo yekufungidzira welding uchishandisa yepakati frequency spot welders, nguva yewelding inonyanya kupesvedzera mhando yeweld, saizi yeHAZ, uye kushanda kwese kwese. Vagadziri nevatsvaguri vanofanirwa kushandirapamwe kumisikidza yakanakira welding paramita inoburitsa yakasimba, yakavimbika welds uchisangana nezvinodiwa zvekugadzira. Kunyatsonzwisisa mabatiro anoita nguva yewelding maitiro anozobatsira mukusimudzira weld mhando uye kurongeka kwechimiro mune akasiyana maindasitiri ekushandisa.
