Porosity feem ntau tshwm sim hauv aluminium welding.
Muaj qee qhov pores nyob rau hauv cov khoom siv hauv paus thiab hauv cov vuam hlau, yog li nws yog ib qho tsim nyog kom tsis txhob muaj qhov hws loj thaum lub sij hawm vuam los xyuas kom meej tias qhov pores tsis dhau tus qauv. Thaum cov av noo tshaj 80℅, vuam yuav tsum nres. Qhov tshwm sim ntawm qhov pores tshaj tus qauv kuj tseem yog 80℅, thiab nws yooj yim los tsim cov khoom xa rov qab.
Vuam nyob rau hauv lub xeev humidity qhia nyob rau hauv daim duab yog heev yuav ua tau ib tug rov qab txiav txim.
Xinfa vuam cov cuab yeej muaj cov yam ntxwv zoo thiab tus nqi qis. Yog xav paub ntxiv, thov mus saib:Vuam & txiav Manufacturers - Tuam Tshoj Vuam & Txiav Hoobkas & lwm tus neeg (xinfatools.com)

Qee zaum cov plua plav dub yuav lo rau qhov vuam, kuv yuav ua li cas?

Qhov tseeb, lub tungsten electrode yog paug, los yog nws kov lub pas dej ua ke los yog lub vuam hlau, thiab txhuas lo rau nws. Tsuas yog thaum lub tungsten electrode huv si tuaj yeem txuas ntxiv mus.
▲ Cov kab mob tungsten electrode yog paj ntoos-puab ▲
Lub sijhawm no, peb tsuas yog yuav tsum tau kho qhov dav ntawm lub tshuab vuam mus rau hauv qab, qhov tam sim no nyob ib ncig ntawm 200, thiab arc vuam yog pib ntawm ib daim ntawm cov khoom seem. Hauv ob peb feeb xwb, lub tungsten electrode yuav tsim ib lub pob me me. Yog tias koj xav welding aluminium zoo, lub pob me me yog cov khoom yuav tsum muaj.

Muab piv aluminium welding rau stainless hlau, kuv nyiam aluminium welding. Nws tsis yog teeb meem li stainless hlau, uas yuav tsum tau swung. Aluminium vuam yog ib qho yooj yim, thiab vuam phom yeej tsis viav vias. Qhov no aluminium raj nrog ib lub liner yog ib tug fillet weld, thiab vuam tsis yog qhov teeb meem.
Thaum kho qhov tam sim no me ntsis, qhov zoo tshaj plaws tam sim no yog qhov uas tuaj yeem tswj tau lub pas dej molten. Qhov kev ua tau zoo ntawm txhua lub tshuab vuam sib txawv, qhov tam sim no yuav txawv, thiab qhov hloov pauv ntawm arc kuj yuav txawv.
