Mid-frequency spot welding inzira inoshandiswa zvakanyanya mumaindasitiri akasiyana siyana, senge mota nekugadzira, yekubatanidza zvinhu zvesimbi. Kuve nechokwadi chemhando yeaya majoini e weld kwakakosha kuchengetedza kutendeseka kwechigadzirwa uye kuchengetedzeka. Ichi chinyorwa chinozoongorora ongororo yezvakajairwa mhando nyaya dzine chekuita nepakati-frequency spot welding joints.
Quality Issue 1: Weld Porosity Weld porosity inoreva kuvapo kwediki voids kana cavities mujoint welded, izvo zvinogona kunetesa chimiro uye kuderedza kuperera kwese kweweld. Zvinhu zvakati wandei zvinogona kuita kuti weld porosity, zvinosanganisira kusakwana gasi rekudzivirira, zvisina kufanira welding paramita, kana yakasvibiswa base simbi. Matanho anobudirira ekudzora emhando, akadai sekutarisa gasi uye kugara uchigadzirisa zvekushandisa welding, zvakakosha kugadzirisa nyaya iyi.
Quality Issue 2: Weld Cracking Weld cracking, kana kuumbwa kwezvimedu mujoint welded, ndechimwe chinhu chinonyanya kunetsa. Zvinogona kuitika nekuda kwekukurumidza kutonhora kwe weld, kusakwana preheating, kana kuwanda kwekunetseka kwakasara. Matanho ekudzivirira senge kudzora kutonhora mazinga, kuita kwakaringana preheating maitiro, uye kushandisa akakodzera mafirita zvinhu zvinogona kubatsira kudzikisira kuputika kweweld.
Hunhu Hunhu 3: Kupinda Kusina Kukwana Kupinda kusina kukwana kunoitika apo weld inotadza kusvika pahukobvu hwakazara hwehwaro zvinhu, zvichikonzera kubatana kusina simba. Zvikonzero zvinokonzeresa nyaya iyi zvinosanganisira kukwenenzverwa kwemagetsi kwazvino, saizi isina kufanira ye electrode, kana kugadzirira kwemajoini. Vashandi vanofanirwa kuwana kudzidziswa kwakakwana uye kugara vachiongorora michina yavo yewelding kuti vaone kupinda kwakaringana uye kuwirirana kwemhando.
Quality Issue 4: Weld Spatter Weld spatter ndiko ejection yeakanyungudutswa simbi zvimedu panguva welding process, izvo zvinogona kutungamira kune njodzi dzekuchengetedza uye kuderedzwa aesthetics. Kupfeka kwakakodzera kwe electrode, kuchengetedza nzvimbo dzebasa dzakachena, uye kugadzirisa maparamendi e welding zvinogona kuderedza kuitika kwe weld spatter.
Hunhu Nyaya 5: Electrode Wear Mamiriro emagetsi emagetsi anoita basa rakakosha mukuwana mawelds emhando yepamusoro. Electrode kupfeka, kunokonzerwa nezvinhu zvakaita seyakanyanya ikozvino kana kusatonhodza kwakaringana, zvinogona kutungamira kune kusawirirana kwemhando uye kuwedzera mari yekugadzirisa. Kushandisa electrode monitoring uye kutsiva mashedhi kunogona kubatsira kugadzirisa nyaya iyi.
Mhedziso: Kuve nechokwadi chemhando yepakati-frequency spot welding majoini kwakakosha kuchengetedza kutendeseka kwechigadzirwa uye kuchengetedzeka mumaindasitiri akasiyana. Nekugadzirisa zvinhu zvakajairika senge weld porosity, kutsemuka, kupinda kusina kukwana, weld spatter, uye kupfeka electrode, vagadziri vanogona kuvandudza maitiro avo ekushongedza uye kugadzira akavimbika, emhando yepamusoro weld majoini. Anoshanda emhando yekudzora nhanho, kudzidziswa kwevashandisi, uye nguva dzose gadziriso yemidziyo zvinhu zvakakosha mukuzadzisa zvinowirirana, zvemhando yepamusoro welds.
