Vuam kev ua haujlwm

Arc - pib thiab Arc - xaus
Thaum pib lub arc, nws yog ib qho tsim nyog yuav tsum ntaus lub arc ua ntej ntawm ntug ntawm qhov welded thiab ces txav mus rau qhov chaw pib ntawm lub vuam tom qab lub arc ruaj khov. Qhov no tuaj yeem zam qhov tsis xws li porosity lossis tsis muaj fusion ntawm arc - pib taw tes. Thaum xaus lub arc, qhov tsim nyog arc - xaus txoj kev yuav tsum tau saws, xws li rov qab - vuam arc - xaus los yog crater - filling arc - xaus. Rov qab - vuam arc - xaus txhais tau hais tias rub lub arc rov qab mus rau ib qho kev ncua deb ntawm sab pem hauv ntej ntawm lub vuam thiab maj mam tua lub arc; crater - filling arc - xaus txhais tau hais tias ntxiv me me ntawm cov vuam hlau ntawm lub qhov crater los sau cov crater ua ntej xaus qhov arc. Ob txoj kev no tuaj yeem tiv thaiv kev tsim cov kab nrib pleb thiab cov kab noj hniav shrinkage.

Vuam Lub kaum ntse ntse thiab kev taw qhia
Lub kaum sab xis ntawm rab phom vuam thiab qhov chaw ntawm qhov vuam feem ntau yog khaws cia ntawm 70 degree - 80 degree . Lub kaum sab xis vuam tsim nyog tuaj yeem ua kom muaj kev tiv thaiv zoo ntawm cov vuam los ntawm cov pa tiv thaiv thiab tiv thaiv cov vuam los ntawm oxidation. Cov kev taw qhia vuam feem ntau siv txoj kev vuam sab laug, uas yog, rab phom vuam txav ntawm sab xis mus rau sab laug thaum vuam. Qhov kev taw qhia vuam no yooj yim rau kev soj ntsuam lub pas dej weld thiab tuaj yeem ua rau cov txheej txheem vuam zoo nkauj dua. Meanwhile, thaum lub sij hawm vuam txheej txheem, vuam phom yuav tsum tau tsiv mus nyob ruaj khov thiab tsis txhob co los xyuas kom meej qhov ncaj thiab uniformity ntawm weld.

 

 

 

Multi-layer thiab Multi-pass Vuam (yog tias tsim nyog)
Rau cov phaj tuab tuab (ze li 6 hli) los yog cov xwm txheej uas yuav tsum tau ua rau cov khoom siv vuam zoo, cov txheej txheem ntau thiab ntau dhau vuam yuav tsum tau ua. Thaum ua cov txheej txheem ntau thiab ntau dhau vuam, nws yog ib qho tsim nyog los tswj qhov kub thiab txias, feem ntau tsis tshaj 150 degree. Lub caij no, lub thickness ntawm txhua txheej ntawm weld yuav tsum tsis txhob tuab heev, feem ntau tswj ntawm 1 - 2mm. Cov weld tom ntej yuav tsum npog 1/3 - 1/2 ntawm qhov dav ntawm qhov vuam dhau los. Qhov no tuaj yeem ua kom cov compactness thiab lub zog ntawm cov vuam thiab tsis txhob muaj qhov tsis xws luag xws li tsis muaj inter-pass fusion.
