Inenge Zisanzwe muri Magnesium Alloy Welding
(1) Ikirahure kibisi
Magnesium ifite aho ishonga kandi ifite ubushyuhe bwinshi. Inkomoko yububasha bukomeye bwo gusudira irakenewe mugihe cyo gusudira. Ahantu ho gusudira no hafi-hake hakunze gushyuha cyane, gukura ingano, gutandukanya kristu nibindi bintu, bigabanya imikorere ihuriweho.
(2) Oxidation no guhumeka
Magnesium ni okiside cyane kandi ihuza byoroshye na ogisijeni. Biroroshye gukora MgO mugihe cyo gusudira. MgO ifite aho ishonga cyane (2 500 ℃) nubucucike bwinshi (3. 2 g / cm-3), kandi biroroshye gukora uduce duto muri weld. Kwishyiriraho ibishishwa bikomeye ntibibuza gusa gushingwa gusudira, ariko kandi bigabanya imikorere ya weld. Ubushyuhe bwo hejuru bwo gusudira, magnesium irashobora guhuza byoroshye na azote mu kirere kugirango ikore nitride ya magnesium. Magnesium nitride gushyiramo slag nayo izatera igabanuka rya plastike yicyuma gisudira kandi bikore imikorere ihuriweho. Ingingo ya magnesium ntabwo iri hejuru (1100 ℃) kandi biroroshye guhumeka munsi yubushyuhe bwinshi bwa arc.
(3) Gutwika no gusenyuka kw'ibice bito
Iyo gusudira ibice bito, bitewe nubushyuhe buke bwa magnesium alloy hamwe nubushuhe buhanitse bwa magnesium oxyde, byombi ntibishobora guhuzwa byoroshye, kuburyo bigoye kureba uburyo bwo gushonga bwikizunguruka mugihe cyo gusudira. Mugihe ubushyuhe buzamutse, ibara rya pisine yashongeshejwe ntirihinduka cyane, bigatuma ikunda gutwikwa no gusenyuka.
(4) Guhangayikishwa nubushyuhe no guturika
Amavuta ya magnesium na magnesium afite coefficente yo hejuru yo kwagura ubushyuhe, hafi inshuro ebyiri z'ibyuma na 1 Inshuro ebyiri, biroroshye gutera impungenge zikomeye zo gusudira no guhindura ibintu mugihe cyo gusudira. Magnesium byoroshye gukora eutectic yo hasi gushonga hamwe nibintu bimwe bivangavanze (nka Cu, Al, Ni, nibindi) (nkubushyuhe bwa Mg Cu eutectic ya 480 ℃, Mg Al eutectic ubushyuhe bwa 430 ℃, Ubushyuhe bwa Mg Ni 508 ℃) , hamwe nubushyuhe bugari buringaniye kandi byoroshye gushiraho ibice bishyushye. Ubushakashatsi bwerekanye ko iyo w (Zn)> 1%, byongera ubushyuhe bwumuriro kandi bishobora gutera gusudira. Ongeraho w (Al) ≤ 10% muri magnesium birashobora gutunganya ingano yingano ya weld no kunoza gusudira. Amavuta ya magnesium arimo akantu gato ka Th afite gusudira neza kandi nta bushake bwo gucika.
(5) Stomata
Amazi ya hydrogène atangwa byoroshye mugihe cyo gusudira kwa magnesium, kandi imbaraga za hydrogène muri magnesium nazo zigabanuka cyane hamwe nubushyuhe bugabanuka.
