Pore ​​teeb meem nyob rau hauv titanium phaj vuam seams

Pores yog ib qho tsis xws luag hauv titanium vuam, feem ntau yog vim muaj kev cuam tshuam ntawm hydrogen. Qhov saum npoo ntawm daim hlau thiab cov khoom siv vuam tsis huv, thiab cov dej noo thiab roj ntawm tus neeg teb xov tooj hnab looj tes, nrog rau cov xuab zeb hais thiab ya plua plav av los ntawm lub kaum sab xis grinder, yog txhua qhov chaw ntawm hydrogen. Kev tsim ntawm qhov pores hauv cov hlau weld feem ntau cuam tshuam rau lub zog qaug zog ntawm kev sib koom tes.
Cov txheej txheem tseem ceeb los tiv thaiv kev tsim ntawm pores yog:
(1) Kev tiv thaiv ntawm neon roj yuav tsum yog ntshiab, nrog ib tug purity ntawm tsis tsawg tshaj li 99.99%. Cov raj yas uas muaj zog yuav tsum tau siv rau cov kav dej, thiab cov raj roj hmab yuav tsum tsis txhob siv.
(2) Ua tib zoo tshem tawm cov organic teeb meem xws li oxide daim tawv nqaij thiab cov roj stains los ntawm qhov chaw ntawm qhov chaw welded thiab vuam hlau.
(3) Siv cov roj tiv thaiv zoo rau lub pas dej molten, tswj tus nqi ntws thiab ntws ntawm argon, thiab tiv thaiv kev kub ntxhov, uas yuav cuam tshuam rau kev tiv thaiv.
(4) Kev xaiv cov txheej txheem vuam tsis raug, ua kom lub sijhawm nyob ntawm cov hlau vuam hauv lub pas dej ua ke, tso cov npuas kom dim, tuaj yeem txo qhov porosity.
(5) Thaum vuam, me me hluav taws xob input yuav tsum tau siv, thiab nws yog qhov zoo tshaj plaws los siv mem tes argon arc vuam. Qhov no tuaj yeem txhim kho kev sib koom ua ke ntawm plasticity, txo qis overheating thiab coarsening, txo deformation, nce qhov tob tob, thiab txo cov tiam ntawm pores.
