埋弧焊管酸洗樣品參數(shù)測(cè)定系統(tǒng)的研發(fā)

R & D of Parametric Measuring System for Etching Test Specimen of SAW Pipe

摘要: 介紹了有別于傳統(tǒng)的酸洗樣品截面參數(shù)測(cè)定方法——計(jì)算機(jī)軟件測(cè)定法，包括酸洗樣品圖像預(yù)處理程序模塊的設(shè)計(jì)，內(nèi)外焊縫寬度、深度、余高、熔寬比、熔深比軟件測(cè)量方法，內(nèi)外焊縫側(cè)面角度、內(nèi)外焊縫焊偏量和重合量的測(cè)量原理等。新開(kāi)發(fā)的測(cè)定系統(tǒng)能提高測(cè)量的準(zhǔn)確性、便捷性及樣品參數(shù)的可存儲(chǔ)性，減少酸洗樣品前期酸洗及打磨的時(shí)間，并能解決測(cè)定誤差大等問(wèn)題。

Abstract: Described in the paper is an unconventional measurement method for sectional parameters of the etch test specimen，i.e.，the computer software measurement method，covering design of program modules for preprocessing of etch specimen image，software measurement of width，depth，excess metal，pool width ratio and pool depth ratio of both outer and inner welds，and measurement principles for side angles and deviation and overlap of outer and inner welds，etc. The newly-developed measurement system will enhance operation accuracy and convenience，and storage capacity of specimen data，shorten time for etching and grinding of the specimen，and solve problems like large error.
