Dab tsi vuam hlau yog phim rau Qib 2 titanium

Rau vuam Qib 2 ua lag luam ntshiab titanium, feem ntau siv thiab pom zoo sib xws vuam hlau yog ERTi-2 (AWS A5.16 tus qauv), uas yog chemically thiab mechanically sib npaug rau Qib 2 puag titanium.

Yog vim li cas rau kev sib piv ERTi-2 hlau:

Nws muaj tib yam tshuaj muaj pes tsawg leeg raws li Qib 2 lub hauv paus hlau, tshwj xeeb tshaj yog tswj qib ntawm oxygen, hlau, thiab impurities.

Xyuas kom cov welded sib koom ua ke muaj zoo ductility, formability, thiab corrosion kuj raws li lub hauv paus hlau.

Haum rau tag nrho cov txheej txheem vuam: TIG (GTAW), MIG (GMAW), thiab plasma vuam.

Qee zaum qhov muaj zog dua me ntsis, ERTi-3 kuj tuaj yeem siv tau, tab sis ERTi-2 tseem yog tus qauv thiab nyiam xaiv rau Qib 2 titanium vuam.

Nyob rau hauv cov txheej txheem vuam kom zoo, qhov corrosion kuj ntawm Qib 2 welded pob qij txha tsis txo qis thiab tseem yuav luag zoo ib yam li cov hlau puag.

Qib 2 yog titanium ntshiab, uas tso siab rau qhov nyias nyias, ruaj khov, thiab nws tus kheej - kho TiO₂ oxide zaj duab xis kom zoo corrosion kuj.

Tsuav yog qhov vuam tau ua tiav raws li qhov tsim nyog argon shielding (kom tiv thaiv qhov vuam thiab cua sov- thaj tsam cuam tshuam los ntawm oxidation, paug, thiab nqus pa), qhov chaw vuam yuav hloov kho cov txheej txheem oxide sai sai.

Yog hais tias lub vuam yog paug los ntawm oxygen, nitrogen, hydrogen, carbon, los yog lwm yam impurities thaum lub sij hawm vuam (xws li, tsis txaus shielding, deg tsis huv), lub weld tej zaum yuav nyuaj, nkig, thiab nws corrosion kuj yuav txo.

Hauv kev lag luam ib txwm muaj nrog cov txheej txheem vuam txheej txheem, Qib 2 welds muaj kev tiv thaiv zoo heev hauv dej hiav txwv, oxidizing acids, organic acids, thiab alkaline ib puag ncig.

Nrog rau kev siv vuam kom raug thiab kev tiv thaiv tag nrho argon, Qib 2 welded pob qij txha tuav zoo heev corrosion kuj, yuav luag sib npaug ntawm lub hauv paus hlau.

Tsuas yog cov vuam tsis zoo lossis kev sib kis yuav ua rau txo qis corrosion.
