Dalili na samarwa da bayani na walda pameld na bakin karfe bututu

Laifi gama gari ne na kowa a cikin walda na bututun karfe, wanda aka bayyana a matsayin karamin ramuka a Weld, da tasiri a kan karfin bututun. Mai zuwa ingantacciya ce mai sauƙin fahimta don bayyana abubuwan da ke haifar da stomaca da yadda za a magance su:

1. Ina pores suke fitowa?

1.1 gas

Karfe da ke narkewa yayin waldi yana ɗaukar gas (kamar oxygen da nitrogen a cikin iska).

Idan gas mai kare (kamar Argon) bai isa ba ko kuma ba shi da tsarkin sama ba, waɗannan gas ba za a iya zubar da waɗannan gas ba har zuwa ƙarshen lokacin da ƙarfe ya sanyaya, samar da kumfa, samar da kumfa.

1.2 abu ba shi da tsabta

Akwai mai, sinadan ruwa ko tsatsa a saman bututun karfe, da gas kamar hydrogen an bazu a babban zazzabi kuma gauraye cikin Weld.

1.3 Walding Welding

A halin yanzu ya yi girma sosai kuma saurin ya yi sauri: zazzabi na molten wurina yana da girma sosai ko kuma tilasta shi yayi sauri, kuma iskar gas ba ta da sauri, kuma iskar ba ta iya tsere.

Ba daidai ba kusurwa mai walda Torch: Iskar kariya ta busa ta da iska, kuma iska ta shiga cikin ruwan wanka.

2. Ta yaya za a guji ramuka na iska?

2.1 tsabta sosai

Tsabta mai, tsatsa da danshi daga saman bututu sosai tare da sandpaper ko barasa kafin waldi.

2.2 sarrafa kare gas

Argon tare da tsarkakakkiyar ≥99.99% ana amfani da shi kuma farashin kwarara yana ci gaba a cikin 15-20l / min.

Guji walƙewa cikin yanayin iska mai ƙarfi, wanda za'a iya kare shi ta hood iska.

2.3 daidaita sigogi na waldi

Zabi mai da ya dace (kamar 90-120a don waya 1.2mm walding waya) don kauce wa wuce kima na yanzu.

Welding Speed ​​ne uniform, ba da sauri (8-12cm / min ba da shawarar).

2.4 Zaɓi Butting Selding

Yi amfani da waya mai ɗauke da silicon (si) ko titanium (ti), kamar er30ssi, don taimakawa cire gas.

Furru-cored waya yana da mafi kyawun juriya fiye da madaidaiciya waya.

2.5 fasaha fasaha

Rike kusurwa tsakanin walgen welding da aikin motsa jiki game da 75 ° don tabbatar da cewa gas ya rufe tafkin tafkin.

Appoornosity galibi ne ta hanyar gas da aikin da ba daidai ba ne. Ta hanyar tsaftace kayan, yana sarrafa gas kuma daidaita sigogi, zaku iya rage rawar jiki sosai kuma tabbatar da ingancin walda!
