Momwe Mungayang'anire Aluminiyamu Ndi Resistance Welding?

Aluminiyamu yakhala ikugwiritsidwa ntchito m'madera osiyanasiyana chifukwa cha kulemera kwake, kukana kwa dzimbiri, kuyendetsa bwino kwa magetsi ndi makhalidwe ena, ndi kuwuka kwa mphamvu zatsopano, kugwiritsa ntchito aluminium kwalimbikitsidwa, ndi kugwirizana kwa aluminiyumu kuwonjezera pa riveting. kuwotcherera, polumikiza mbale ya aluminiyamukukana kuwotchererandi njira yofunikira, zochitika zogwiritsira ntchito kuwonjezera pa ntchito zamakono zamafakitale, Zimagwiritsidwa ntchito kwambiri m'magalimoto atsopano amphamvu, zamlengalenga ndi zina.

Ubwino wa kukana mbale za aluminiyamukuwotcherera malozodziwikiratu, popanda kuwonjezera zipangizo wothandiza, kokha ndi m'munsi zitsulo kusungunuka akhoza kupanga amphamvu solder olowa.Aluminiyamumu mlengalenga nthawi zambiri amakhala ndi wosanjikiza wa okusayidi filimu, zotayidwa kusungunuka mfundo 660 digiri Celsius, ndi filimu okusayidi ndi aluminium okusayidi, kusungunuka kwake ndi za 2000 madigiri, ndi kusungunula m'munsi zinthu kupanga pachimake choyamba kuswa oxide wosanjikiza. , amenenso ndi aluminiyamu malo kuwotcherera ndondomeko amaonedwa kuti zovuta chifukwa.

KuwotchereraEzidaSchisankho

Kusankhidwa kwa mbale ya aluminiyamumakina kuwotcherera malo, inverter yapakatikati yamagetsi yamagetsi ya DC chifukwa cha kutulutsa kwake pano ndi DC, yokhala ndi mphamvu zambiri zamatenthedwe, ndiye chisankho choyamba chowotcherera mbale za aluminiyamu. Magetsi amtundu wachitatu wagawo lachiwiri ndi owongolera theka-wave, capacitive mphamvu yosungirako mphamvu ngakhale zotulutsa zake ndi DC koma nthawiyo ndi yaifupi kwambiri, kotero magwiridwe ake athunthu siwofanana ndi ma frequency inverter DC spot welder, awa. magetsi ali ndi ntchito koyambirira, zochitika zamtsogolo zidzacheperachepera.

Aluminiyamu mbale malo kuwotcherera ndondomeko, zotayidwa mbale madutsidwe ndi matenthedwe madutsidwe chiŵerengero ndi mkulu, kotero kufunika kwakukulu panopa ndi yoyenera kuwotcherera nthawi, amene amafuna chidwi mfundo zotsatirazi:

1. Mphamvu ya zidazo iyenera kukhala yayikulu mokwanira kuti iwonetsetse kuti zomwe zikuchitika pano zitha kukhala zochulukirapo pakanthawi kochepa, nthawi zambiri 2-3 kuposa momwe amawotchera mawanga a kaboni;

2. Elekitirodi imafuna madzi ozizira ozizira, ndipo kutentha kumatha kuchotsedwa mwamsanga mutatha kuwotcherera;

3. Kuzungulira kozungulira kwa kutsogolo kwa electrode kuyenera kufananizidwa, ndipo makulidwe osiyanasiyana a mbale ayenera kukhala ndi magawo osiyanasiyana, ndipo mfundoyi sayenera kukhala yotsika kuposa SR25;

4. Ma electrode awiri ayenera kufanana ndi makulidwe a mbale, ndipo m'mimba mwake electrode pansi pa 1.0MM ya mbale ndi ¢13; Mapepala makulidwe 1.0-1.5 Electrode awiri ndi ¢16; Mapepala makulidwe 1.5-2.0 Electrode awiri ndi ¢20; Mbale makulidwe pamwamba 2.0 elekitirodi awiri si zosakwana ¢25;

5. Elekitirodi zakuthupi amapangidwaaloyi yamkuwandi ma conductivity apamwamba kapena mkuwa wouma, ndipo ma conductivity si osachepera 80% IACS;

6. Kukumana ndi zida zapamwamba zogulitsira, pamwamba pa mbale ya aluminiyamu iyenera kukhala yodetsedwa, pickling kapena kupukuta, ndi kukana kwapamtunda kwa A-level joint of aviation / asilikali ankhondo ayenera kulamulidwa pa 50 microohm-100 microohm;

KuwotchereraQmoyoIkuyang'ana

Aluminiyamu mbale malo kuwotcherera pambuyo mayeso makamaka sanali owononga kuyezetsa ndi kuwonongeka kudziwika magulu awiri, zosawononga makamaka kudzera zithunzi, X-ray ndi akupanga kuzindikira, kuwonongeka kuzindikira makamaka kutambasula, nthawi otsika ndi kuzindikira zina, njira zodziwira enieni ndi motere. :

1. Kuyang'anira maonekedwe, kuphatikizapo mawonekedwe a solder joint, solder olowa mtundu, indentation kuya, etc.;

2. X-ray kudziwika, filimu kudziwika awiri a weld pachimake, kaya weld pachimake ming'alu, shrinkage ndi zolakwika zina;

3. Low-mphamvu kuzindikira, 15-25 zina pambuyo kagawo dzimbiri wa olowa solder, kudziwa kuwotcherera permeability, kuwotcherera zilema, etc.;

4. Mayesero amanjenje, waukulu mayeso solder olowa mphamvu;

5. Mayeso ovula, kuvula kapena kung'ambika kwa ma solder, omwe amagwiritsidwa ntchito kwambiri pozindikira mphamvu zapamalo ndikutsimikizira kukula kwapakati.

6. Akupanga kuzindikira, ndi kukweza kwa akupanga kudziwika luso, kugwiritsa ntchito malo kuwotcherera kudziwika akupitiriza kulimbikitsa, mwa kuyerekezera unanyezimira waveform, komanso kukhwima kwa digito kujambula luso, polycrystalline mutu akupanga kudziwika adzakhala chisankho chabwino kwa kuyesa kosawononga kwa kuwotcherera mawanga a aluminiyamu.
