Zomwe Zimayambitsa Ming'alu mu Mid-Frequency Spot Welds

Kuwunika kwa zifukwa za ming'alu ya ma welds ena amapangidwa kuchokera ku mbali zinayi: macroscopic morphology of the welding joint, microscopic morphology, energy spectrum analysis, and metallographic analysis of the welding joint.makina owotcherera apakati pafupipafupikuwotcherera. Kuwona ndi kusanthula kumasonyeza kuti kuwotcherera ming'alu amayamba chifukwa cha mphamvu zakunja, makamaka chifukwa cha kukhalapo kwa zofooka zambiri zowotcherera, ndi njira zowotcherera zosayenera komanso kuyeretsa kosakwanira kwa malo omwe amawotcherera ndizomwe zimapangitsa kuti zikhale zovuta kwambiri. Pansipa pali zovuta zingapo zomwe zimayambitsa kusweka kwa mafupa:

Kuphulika kwa Crystalline:
Panthawi yolimba ndi crystallization ya dziwe lowotcherera, ming'alu imapanga malire a tirigu wa chitsulo chowotcherera chifukwa cha tsankho la crystallization ndi kupsinjika kwa shrinkage ndi kupsyinjika. Ming'alu iyi imachitika mkati mwa weld.

Liquation cracks:
Pa kuwotcherera, mchikakamizo cha kutentha pachimake mu kuwotcherera kutentha mkombero, intergranular zitsulo pafupi msoko weld mu interlayers wa Mipikisano wosanjikiza welds akhoza kachiwiri kusungunuka chifukwa Kutentha. Pansi pa kupsinjika kwina, ming'alu imayamba m'malire ambewu ya austenite, chodabwitsa chomwe nthawi zina chimatchedwa kung'amba kotentha.
Kutentha kwakukulu kwapang'onopang'ono-ductility:
Akamaliza madzi gawo crystallization, monga welded olowa zitsulo akuyamba kuziziritsa ku zinthu ductile kuchira kutentha, kwa zipangizo zina, utakhazikika kwa ena kutentha osiyanasiyana, ndi ductility amachepetsa chifukwa cha kugwirizana kwa kupsyinjika mlingo ndi zinthu zitsulo, kutsogolera. kusweka m'malire a tirigu a chitsulo cholumikizira. Kusweka kotereku kumachitika m'dera lomwe limakhudzidwa ndi kutentha kutali ndi mzere wophatikizika kuposa ming'alu yamadzi.
Yatsaninso ming'alu:
Pambuyo kuwotcherera, panthawi ya chithandizo cha kutentha kwa nkhawa kapena popanda chithandizo chilichonse cha kutentha, ming'alu imayamba m'mphepete mwa malire a austenite wachitsulo pa kutentha kwina. Kutenthetsanso ming'alu ndi nkhani yofunika kwambiri pakuwotcherera zitsulo zotsika kwambiri zamphamvu kwambiri, makamaka muzitsulo zazitsulo zokhala ndi aloyi zapamwamba za carbon ndi zitsulo zosagwira kutentha zomwe zimakhala ndi zinthu zambiri zopanga carbide (monga Cr. , Mo, V). Kuthana ndi zolakwika izi kumatenga nthawi ndipo kumakhudza kwambiri kupanga.
Suzhou Agera Automation Equipment Co., Ltd imakhazikika pakupanga makina opangira makina, kuwotcherera, zida zoyesera, ndi mizere yopanga, makamaka yotumikira mafakitale monga zida zapakhomo, kupanga magalimoto, zitsulo zamapepala, ndi zamagetsi 3C. Timapereka makina owotcherera makonda, zida zowotcherera zokha, ndi mizere yopangira zowotcherera potengera zosowa zamakasitomala, kupereka njira zoyenera zodziwikiratu kuti zithandizire makampani kuti asinthe mwachangu kuchoka ku njira zopangira zakale kupita ku njira zopangira zomaliza. Ngati muli ndi chidwi ndi zida zathu zokha komanso mizere yopanga, chonde titumizireni: leo@agerawelder.com
