Nawa kuka sani game da kayan walda? Kar a manta da babban jimlar! (I)

1. Galvanized takardar

Galvanized takardar ya kamata ya zama mafi yawan kayan walda. Yawan zafin jiki na zinc yana da ƙasa da ƙasa fiye da wurin narkewar ƙarfe, don haka yana da sauƙin siffa da walda yayin walda. Tabbas, saboda wannan, takardar galvanized kuma za ta sami lahani a lokacin walda. Kamar yadda zinc ɗin ke ci gaba da ƙafewa, tururin da aka samar zai shiga cikin walda don samar da pores ko yanke. Dace da Laser waldi.

2. Bakin karfe

Sau da yawa muna jin labarin kayan bakin karfe. Kayan walda gabaɗaya sun haɗa da bakin karfe austenitic, bakin karfe na ferritic, da bakin karfe na martensitic.

1. Austenitic bakin karfe
Austenitic bakin karfe yana da mafi kyawun aikin walda, ƙananan ƙarancin zafi amma babban ƙimar sha. Lokacin da aka yi amfani da shi a cikin waldawar laser, saurin walda yana da sauri kuma shigar da zafi kadan ne. Austenitic bakin karfe ne mafi amfani a cikin Cr Ni jerin bakin karfe ayyukan walda, kuma Laser waldi ne mafi amfani da walda austenitic bakin karfe, yadda ya kamata guje wa nakasawa da kuma saura.

2. Ferritic bakin karfe
Fa'idodin ferritic bakin karfe ne super tauri da kuma mai kyau ductility. A cikin tsarin walda, tasirin yana da kadan. Misali, austenite da martensite na iya fashe yayin waldawar Laser, amma ferrite yana rage yiwuwar hakan.

3. Martensitic bakin karfe
Bakin Karfe na Martensitic na iya zama bakon kowa ga kowa, saboda aikin sa ya yi kasa da na bakin karfe na austenitic da bakin karfe. Cold fatattaka sau da yawa faruwa a lokacin da martensitic bakin karfe da ake amfani da waldi, kuma waldi sakamako ba shi da kyau. Wasu ayyukan walda tare da ƙananan buƙatu da farashi ana amfani da su lokaci-lokaci, kuma yawan amfani ba shi da yawa.

3. Alloy karfe

Har ila yau, karfen alloy yana da saurin fashewa a lokacin walda, amma fa'idarsa ita ce ana iya walda shi kai tsaye a yanayin zafi, kuma taurinsa yana da yawa. Ga wasu aikace-aikace tare da ƙaƙƙarfan buƙatun taurin, walƙiyar gami da ƙarfe shine zaɓi mai kyau. Don walƙiyar gami da ƙarfe, walƙiya ta laser galibi ana amfani da ita. Wasu na'urorin watsa motoci, har ma da sassan injin jirgin, za a yi amfani da su don walda karafa.
