Kuwotcherera kwa arc ndi njira yowotcherera ya arc pansi pa njira yoyaka moto yosanjikiza. Kuwotcherera arc pakati pa waya ndi kuwotcherera kutentha kutentha kwa arc ndi arc kuwotcherera waya malekezero pafupi ndi m'munsi zitsulo ndi solder amasungunula, kupitiriza kudyetsa waya, ndi kumapitirira limodzi trajectory, ndi Arc weld dziwe olimba zitsulo amachotsedwa kuwotcherera chitsulo chosungunuka. solder imakhazikika mu chipolopolo chophimba pamwamba pa weld slag, slag ya dziwe losungunuka ndi zitsulo zowotcherera kuti atetezedwe ku arcing ndi dziwe ndi kulowerera kwa mpweya wakunja.

Kulowetsedwa kwa arc kuwotcherera arc, waya, waya ndi chosokoneza chosinthira zinthu zotere zimachitika ndi makina, zimadziwika kuti kuwotcherera arc kumizidwa. SAW ili ndi izi zabwino izi: ① kuchuluka kwa makina, chifukwa ma welder amafunikira luso lochepa; ② kuwotcherera panopa, akhoza kuchepetsedwa weldments poyambira, mkulu kuwotcherera dzuwa; ③ akhoza kupatukana ndi kukhudzana zitsulo solder ndi mpweya, zoteteza zotsatira zabwino, mkulu weld khalidwe; ④ yokutidwa ndi ma arc radiation, malo abwino ogwirira ntchito. The sangathe ndi kuti mwa lathyathyathya udindo kuwotcherera, zipangizo kuwotcherera ndi zida tooling wovuta.

High-frequency kuwotcherera ku kutentha kwapang'onopang'ono kwaposachedwa kwa workpiece, ndiyeno kugwiritsa ntchito zolumikizira zowotcherera (onani chithunzi) kumapangidwa. Kutentha kwapang'onopang'ono kumakhazikika pamwamba pa kondakita ndikuyenda m'njira yocheperako pang'onopang'ono pa mfundo, pakali pano kumatenthedwa ndi kutentha kwa malo ogwirira ntchito kuti atenthedwe, malo a thermoplastic afikira, kapena gawo losungunuka pang'ono, kutuluka. chitsulo chosungunula pa workpiece ndi kukanikiza zitsulo okusayidi, aumbike zolumikizira welded. Kuwotcherera kwafupipafupi kwafupipafupi wa 60 mpaka 500 kHz. Kuwotcherera ma frequency apamwamba kwambiri komanso kuwotcherera ma frequency apamwamba awiri.

① High Frequency Resistance Welding: kukhudzana ndi gudumu kapena ngati sub-electrode high-frequency mafunde pa workpiece, oyenera mosalekeza longitudinal msoko welded chitoliro ndi ozungulira lap msoko kuwotcherera, boiler chubu ndi zipsepse kutentha exchanger ozungulira welded zipsepse, kunja awiri. chitoliro akhoza kukhala 1200 mm ndi khoma makulidwe a 16 mm, m`mimba mtengo kuwotcherera elekitirodi makulidwe 9.5 mm, mkulu zokolola.
② kuwotcherera kwapang'onopang'ono: chubu chaching'ono cham'mimba mwake ndi makulidwe a khoma la chogwirira ntchito ndi koyilo yotenthetsera yotenthetsera imatha kuwotcherera ndi mainchesi akunja a 9 mm ndi chubu la mipanda 1 mm. Amagwiritsidwa ntchito pang'ono m'mimba mwake kotalika chitoliro kuwotcherera ndi mkuwa angagwiritsidwenso ntchito girth weld, koma kugwiritsa ntchito mphamvu ndikokulirapo kuposa kuwotcherera kwanthawi yayitali. Magawo akuluakulu omwe amakhudza mawonekedwe a kuwotcherera kwapang'onopang'ono ndi kuchuluka kwamphamvu kwamagetsi, mphamvu, mawonekedwe a workpiece, liwiro la kuwotcherera ndi kukakamizidwa kuchokera kufinya, ma elekitirodi (kapena coil induction) ndikufinya zodzigudubuza. Major zida pafupipafupi mphamvu magetsi, workpiece kupanga zida ndi extrusion makina. Kukhazikika kokhazikika kowotcherera kwanthawi yayitali, zokolola zambiri komanso mtengo wotsika. Pakuti mkulu-mwachangu basi kupanga mzere, kupanga njira zapamwamba anatumbula chubu.
