Kulungile-Ukulungisa EyakhoMFDC Spot Welder: Isikhokelo sokuSeta ngokukhawuleza

Ukufumana ii-welds ezihambelanayo kunyemedium-frequency ngqo current (MFDC) spot weldersifuna ulungelelwaniso lwezicwangciso ezintathu eziphambili:yangoku, ixesha, kunye noxinzelelo. Nantsi indlela yokucofa kubo:

1. Uhlengahlengiso lwangoku: Lawula ubushushu

Qala phantsi: Kwintsimbi ye-0.8mm ethambileyo, qalisa kwi-200-300A.

Uvavanyo kunye nokwanda: Nyusa okwangoku kwi-10% yamanyathelo ude ubone:
✅ Ukungena ngokupheleleyo kwe-nugget (akukho malungu abuthathaka)
❌ Akukho sitshizi okanye sitshise-ngadlulanga (ibonisa ubuninzi bangoku)
Ingcebiso ye-aluminium: Sebenzisa i-30-50% yangoku ephantsi kunentsimbi ngenxa ye-conductivity ephezulu.

2. Ixesha le-Welding: Lawula uBubushushu bexesha

Intsimbi: Ixesha elifutshane + eliphezulu langoku (umzekelo, 3-6 sec @ 320A for M6 nuts)

I-Aluminiyam / iCopper: Ixesha elide + eliphantsi langoku
Isilumkiso: Inde kakhulu=i-electrode encamathelayo; Mfutshane kakhulu=indibaniselwano engaphelelanga.

3. Uxinzelelo lwe-Electrode: Qinisekisa uQhagamshelwano

Amaphepha amancinci (<1mm): 0.3-0.5 MPa

Thick plates (>3mm): 0.8-1.2 MPa
Umlinganiselo obalulekileyo: Ukunyusa uxinzelelo lwe-5% kuyo yonke i-10% yokunyusa okwangoku.
Ukulungiswa kwentsimbi yeGalvanized: Sebenzisa Omkhulu kunoko okanye ulingana noxinzelelo lwe-0.6MPa ukukhusela i-zinc spatter.

4. ULondolozo lwe-Electrode: Ukuhambelana ngundoqo

Iingcebiso zokulola: Sila zonke iiweld ezingama-50-100 ngephepha elicolekileyo.

Pholisa kakuhle: Jonga ukuhamba kwamanzi ngeveki - ii-electrode ezithambileyo zibangela ukukhukuliseka.

I-Anti{0}} intonga: Faka intlama yegraphite xa udibanisa ialuminiyam.

Iingcebiso zePro zokuSeta

• Vavanya umntu ngamnye: Lungisa iparamitha enye ngexesha.
• Qinisekisa ukuhambelana: Ukulinganisa ububanzi be-nugget - ukuhluka<0.2mm.
• Gcina iinkangeleko: Gcina useto olululo lwezixhobo ezahlukeneyo.

Isiphumo sokwenyani: Umzi-mveliso owandisiweyo wobomi be-electrode ukusuka kwiiyure ezingama-500 ukuya kwi-1200 ngokunxitywa rhoqo kweengcebiso kunye nokuphucula ukupholisa.
