1st Welding Nickel raws li alloys rodsyog ib qho ntawm cov khoom tseem ceeb tshaj plaws hauv kev lag luam engineering
Vim tias Vuam Nickel raws li alloys rods tuaj yeem siv rau hauv ntau qhov chaw thiab lub sijhawm, kev siv tshuaj tiv thaiv corrosion ntawm dej thiab kub, kev siv zog siab ntawm qhov kub thiab txias, ductility thiab toughness daim ntaub ntawv ntawm qhov kub thiab txias, tshwj xeeb kev siv hluav taws xob, thiab lwm yam kev siv lub cev. khoom. Vuam Nickel raws li alloys rods raug xaiv rau txhua lub sijhawm.
2. Vuam Nickel raws alloys rodstuaj yeem muab cov khoom tshwj xeeb hauv qee daim ntawv thov vuam.
Piv txwv li, rau vuam 9% nickels hlau hauv Ni Cr Mo vuam series. Cov khoom tseem muaj siab heev li welded lub zog thiab cuam tshuam toughness ntawm kua nitrogen kub.
Vuam Nickel raws li alloys rods siv rau vuam cam khwb cia hlau tuaj yeem diluted nrog hlau thiab carbon los tswj ductility thiab muab cov yam ntxwv zoo machining.
3. Vuam Nickel raws li alloys rods tuaj yeem siv rau kev sib txawv vuam, zoo li nruab nrab ntawm carbon steel thiab stainless hlau ua qhov sib txawv ntawm qhov sib txawv raws li cov khoom siv hloov pauv rau thermal expansion coefficient thaum siv qhov kub thiab txias. Piv nrog rau cov hlau, Vuam Nickel raws li alloys rods yuav siv tau ntawm qhov kub thiab txias nyob ze rau 1200 degree (2190F) vim hais tias cov matrix ntawm cov khoom tov alloys tswj austenite los ntawm cov khoom mus rau xoom kiag li. Vuam Nickel raws li alloys rods nrog cov khoom siv tsim nyog muab cov txiaj ntsig zoo corrosion thiab tuaj yeem siv rau hauv cov ntawv thov xws li hluav taws xob thiab pob zeb.
Nws tau raug siv rau ntau yam kev lag luam xws li kev ua tshuaj lom neeg, aerospace, thiab kev tswj hwm ib puag ncig
Yuav ua li cas txog qhov weldability ntawm nickel-base alloys rods?
Cov txheej txheem tseem ceeb rau vuam nickel alloys rods muaj xws li roj vuam, arc vuam, tsis siv neeg submerged arc vuam, thiab roj shielded vuam.
1st Gas vuamfeem ntau yog siv rau vuam me me npib tsib xee alloy Cheebtsam nrog ib tug tuab ntawm tsawg tshaj li 3 hli, feem ntau yog siv ib tug nruab nrab oxygen acetylene nplaim.
2nd Arc vuamyog siv rau vuam hlau nrog lub thickness ntau tshaj 1.5 hli. Thaum welding thicker npib tsib xee alloys, nws yog qhov zoo tshaj rau preheat lub welded ob leeg mus rau 200-250 degree los xyuas kom meej ib tug ntom thiab zoo tsim weld seam thaum lub sij hawm ntau txheej vuam. Vuam feem ntau yog ua los ntawm tooj liab pads.
3rd Thaum tsis siv neeg submerged arc vuam nickel alloys, alkaline (tsawg silicon hom) lossis oxygen dawb siab fluorine hom fluxes tuaj yeem siv. Qhov sib xyaw ntawm electrode vuam hlau yuav tsum nyob ze rau cov khoom siv hauv paus, thiab txoj kab uas hla ntawm vuam hlau yog ywj siab ntawm cov tuab ntawm cov hlau. Nws feem ntau yog xaiv raws li daim ntawv sib koom ua ke, thiab feem ntau yog 3-5mm. Cov phaj loj dua 6 hli feem ntau xav tau V-puab lossis X-puab zawj. Copper pads los yog flux pads yuav tsum tau siv rau welding thaum cov npoo ntawm cov pob qij txha yog tag nrho melted.
4th Gas shielded vuam yog txoj hauv kev tseem ceeb rau vuam nickel alloys, feem ntau siv cov hlau xaim hlau uas muaj cov deoxidizers thiab nitride ntsiab lus, thiab vuam nrog luv luv arc siab tam sim no. Thaum welding ntau txheej, tom ntej no weld yuav tsum tau welded tom qab lub weld yav dhau los tau txias tag lawm thiab deg cov kab mob raug tshem tawm.
Tsis tas li ntawd, hluav taws xob slag welding, tiv tauj vuam, thiab diffusion vuam tuaj yeem siv los ua cov nickel alloys.
Yuav ua li cas xaiv qhov haum ntawm nickel-base alloys rods thiab vuam txoj kev?
