Umatshini wokuwelda umthungo ngokuzenzekelayo usebenzisa i-electrode yevili ejikelezayo ukuze ibambe kwaye ihambise amashiti esinyithi aqengqelekayo ngelixa i-welding yangoku elawulwayo idlula ngokudibeneyo. Le yangoku idala uthotho lweenuggets ze weld ezigqitheneyo, zenza umthungo oqhubekayo onokuthi uvavanywe ukomelela kunye nokuvuza{1}} kokuqina.
I-automation ilawula ngaphezu kwe-welding yangoku. Ngokuxhomekeke kwisixhobo, inokuthi ilungelelanise ukujikeleza kwe-electrode, isantya sokuhamba, uxinzelelo lwe-welding, ii-pulses zangoku, indawo yokusebenza kunye nokubekwa esweni kwemveliso. Eli nqaku lichaza indlela inkqubo welding kunye nenkqubo yolawulo oluzenzekelayo zisebenza kunye, ingqalelo ingakumbi MFDC ukumelana umthungo welding.
Usebenza njani umatshini wokuWelding we-Resistance Resistance Seam
| Inyathelo | Kwenzekani |
|---|---|
| 1. Ukuma | I-fixture ilungelelanisa amaphepha awelanayo kwindawo efunekayo yomthungo. |
| 2. Ukubamba | Ii-electrode zamavili zisebenza ngamandla ukuseka unxibelelwano lombane oluzinzileyo. |
| 3. Ukuwelda | I-pulses yangoku elawulwayo yenza ubushushu kwi-interface phakathi kwamaphepha. |

Umsebenzi ophambili we-MFDC seam welder uxhomekeke kwi-synergy egqibeleleyo phakathi kwe-Medium Frequency Inverter Technology kunye ne-Resistance Heating Effect. Inkqubo engundoqo ibandakanya ukuguqula izigaba ezithathu-zamandla e-AC (ngokwesiqhelo yi-60Hz e-US) kumandla e-DC ngokusebenzisa ibhulorho yokulungisa. La mandla e-DC ajikwa zizixhobo zamandla (ezifana neemodyuli ze-IGBT) kumandla aphakathi -amaxesha e-AC, ukusuka kwi-1,000 Hz ukuya kwi-5,000 Hz. Ekugqibeleni, oku kwehliswa yi-MF transformer kwaye kulungiswe kwakhona ukuze kuphume i-welding ye-DC egudileyo, ezinzileyo yangoku.
Le ndlela yokusebenza yahluke ngokusisiseko kwiiwelder eziqhelekileyo ze-AC.
