Nyob rau hauv xyoo tsis ntev los no, nrog rau kev txhim kho kev lag luam, tshwj xeeb yog nrog kev hloov kho tas mus li ntawm kev hloov kho thiab qhib Up, Tuam Tshoj txoj kev lag luam kev lag luam tau ua tiav. Nyob rau tib lub sijhawm, Tuam Tshoj tau ua tiav qhov tseem ceeb hauv kev vuam ntawm pipelines thiab lwm yam haujlwm engineering. Titanium vuam yog ib hom vuam vuam yog ib hom vuam, thiab kev tswj hwm zoo ntawm cov txheej txheem vuam muaj qhov cuam tshuam tseem ceeb ntawm cov xim ntawm Weld Seam. Due to the intuitive nature of titanium weld color, the study of the relationship between titanium weld color and welding quality is of great significance. Raws li xyoo ntawm kev tshawb fawb thiab kev ua haujlwm hauv kev tswj hwm kev sib raug zoo thiab cov xim ntawm titanium vuam, vam tias yuav pab txhawb rau kev tshawb fawb hauv daim teb no.
1. Cov teebmeem ntawm cov pa oxygen thiab nitrogen
Oxygen thiab nitrogen intererstitial fusion nyob rau hauv titanium ua rau lattice distortion, nce deformation thiab hardness, tab sis txo cov zog thiab tawv. Lub xub ntiag ntawm vuam oxygen thiab nitrogen hauv Weld Seam yog tsis txaus siab thiab yuav tsum zam.
2. Qhov cuam tshuam ntawm hydrogen
Qhov nce ntawm hydrogen yuav ua rau ib qho kev cuam tshuam zoo ntawm titanium weld hlau, thaum cov yas yuav txo qis me ntsis, thiab cov dej kas yuav ua rau brittleness ntawm kev sib koom tes.
3. Qhov cuam tshuam ntawm carbon
At room temperature, carbon is solid dissolved in titanium in the form of gaps, increasing strength and decreasing plasticity, but not as obvious as oxygen and nitrogen. Thaum cov ntsiab lus carbon ntau dua rau cov solubility, nyuaj thiab brittle tic yog tsim tawm, uas tau faib rau hauv lub network thiab nquag tawg. Tus qauv hauv tebchaws stipulates uas cov pa roj carbon cov ntsiab lus hauv titanium alloys yuav tsum tsis pub tshaj 0.1%. Thaum lub sij hawm vuam, roj stains ntawm qhov chaw ua haujlwm thiab vuam hlau tuaj yeem nce cov ntsiab lus carbon, yog li nws yuav tsum tau ntxuav kom huv si thaum vuam.
