Kev Ntsuam Xyuas luv luv ntawm Cov Txheej Txheem Txuj Ci Ntawm 6 Cov Txheej Txheem Vuam Ntau

1. Kev tuav arc vuam

Kev tuav arc vuam yog qhov ntxov tshaj plaws tsim thiab tseem yog txoj kev siv dav tshaj plaws ntawm ntau yam arc vuam txoj kev. Nws siv cov electrode coated nrog xim raws li cov electrode thiab muab tub lim hlau. Lub arc hlawv ntawm qhov kawg ntawm cov electrode thiab qhov chaw ntawm lub workpiece yuav tsum tau welded. Nyob rau hauv qhov kev txiav txim ntawm arc cua sov, txheej txheej tuaj yeem tsim cov roj los tiv thaiv lub arc ntawm ib sab, thiab ntawm qhov tod tes, nws tuaj yeem tsim slag npog lub pas dej molten los tiv thaiv kev sib cuam tshuam ntawm cov hlau molten nrog cov roj av ib puag ncig. Lub luag haujlwm tseem ceeb ntawm slag yog los tsim cov tshuaj tiv thaiv lub cev thiab tshuaj lom neeg nrog cov hlau molten lossis ntxiv cov ntsiab lus alloying los txhim kho cov khoom ntawm cov hlau.

Phau ntawv arc vuam cov cuab yeej yog yooj yim, portable thiab saj zawg zog hauv kev ua haujlwm. Nws tuaj yeem siv rau vuam luv seams hauv kev saib xyuas thiab sib dhos, tshwj xeeb tshaj yog rau vuam nyuaj - mus rau - mus txog qhov chaw. Kev tuav arc vuam nrog cov khoom siv electrodes tuaj yeem siv rau feem ntau cov pa roj carbon steel, stainless hlau, cam khwb cia hlau, tooj liab, txhuas, npib tsib xee thiab lawv cov alloys.

2. Tungsten gas shielded arc vuam

Qhov no yog ib qho uas tsis yog - melting electrode gas shielded arc vuam, uas siv cov arc nruab nrab ntawm tungsten electrode thiab cov khoom ua haujlwm los yaj cov hlau los ua ib qho kev sib txuas. Lub tungsten electrode tsis yaj thaum lub sij hawm vuam thiab tsuas yog ua raws li ib tug electrode. Nyob rau tib lub sijhawm, argon lossis helium roj yog pub rau hauv lub nozzle ntawm vuam teeb rau kev tiv thaiv. Nws tseem tuaj yeem ntxiv cov hlau ntxiv raws li qhov xav tau. (Feem ntau hu ua TIG vuam nyob hauv lub ntiaj teb).

Tungsten gas shielded arc vuam tuaj yeem tswj tau qhov cua sov, yog li nws yog ib txoj hauv kev zoo rau kev sib txuas cov ntawv hlau thiab hauv qab vuam. Txoj kev no tuaj yeem siv rau kev sib txuas ntawm yuav luag txhua cov hlau, tshwj xeeb tshaj yog tsim rau vuam aluminium, magnesium thiab lwm yam hlau uas tuaj yeem tsim cov oxides refractory thiab cov hlau nquag xws li titanium thiab zirconium. Lub vuam zoo ntawm txoj kev vuam no yog siab, tab sis piv nrog rau lwm yam arc vuam, nws vuam ceev yog qeeb dua.

3. Molten electrode gas shielded arc vuam

Txoj kev vuam no siv cov arc hlawv ntawm qhov txuas txuas txuas txuas txuas txuas thiab cov khoom ua haujlwm raws li qhov chaw tshav kub, thiab cov roj shielded arc sprayed los ntawm lub teeb nozzle rau vuam. Cov roj shielding feem ntau siv hauv MIG vuam yog: argon, helium, CO2 lossis sib xyaw ntawm cov roj no. Thaum argon los yog helium yog siv los ua cov roj tiv thaiv, nws yog hu ua MIG welding (hu ua MIG vuam hauv ntiaj teb). Lub ntsiab kom zoo dua ntawm MIG vuam yog tias nws tuaj yeem yooj yim welded nyob rau hauv ntau txoj haujlwm, thiab nws kuj muaj qhov zoo ntawm vuam ceev ceev thiab siab deposition npaum li cas.

MIG / MAG welding tuaj yeem siv rau feem ntau cov hlau loj, suav nrog carbon steel thiab hlau alloy. MIG vuam yog tsim rau stainless hlau, txhuas, magnesium, tooj liab, titanium, zirconium thiab nickel alloys. Txoj kev vuam no kuj tseem siv tau rau arc qhov chaw vuam.

4. Laser vuam

Laser vuam yog ib qho vuam uas siv lub laser beam tsom los ntawm lub siab -lub zog coherent monochromatic photon kwj raws li qhov cua sov. Txoj kev vuam no feem ntau suav nrog lub zog txuas txuas ntxiv laser vuam thiab lub zog hluav taws xob laser vuam. Qhov zoo ntawm laser vuam yog tias nws tsis tas yuav tsum tau nqa tawm hauv lub tshuab nqus tsev, tab sis qhov tsis zoo yog tias lub zog nkag mus tsis muaj zog li electron beam vuam. Kev tswj xyuas lub zog muaj tseeb tuaj yeem nqa tawm thaum lub sijhawm laser vuam, kom cov vuam ntawm precision micro li tuaj yeem pom tau. Nws tuaj yeem siv tau rau ntau cov hlau, tshwj xeeb tshaj yog los daws cov vuam ntawm qee qhov nyuaj-rau- vuam hlau thiab cov hlau sib txawv.
