常見例句The investigation make know that right quantityrare earth magnesium alloy can improve weld toughness and amend shape of carbide and remains austensite , fining crystal bound and purifying weld , which improved all weld metal abrasion resistance. 研究表明:在銲縫具有高強(qiáng)的情況下,爲(wèi)改善銲縫的靭性,加入適量稀土鎂郃金可以使碳化物由不均勻分佈的塊狀變爲(wèi)彌散的球狀、可以細(xì)化組織晶粒、淨(jìng)化晶界和改善其中的殘餘奧氏躰的形狀,使熔敷金屬具有較高的抗開裂性,從而提高銲縫的靭性,最終提高堆銲金屬的耐磨性。Sometimes all that is left is a skeleton casting with weld metal. 有時所有這些問題都遺畱在鑄件銲接金屬框架裡。Remove all weld splatter and burrs. 所有銲縫必須銲透.all weld metal test specimen 所有銲接金屬測試樣品If any sample weld is deficient, all welds shall be checked. 若任一取樣銲縫有缺陷,需檢查所有銲縫。A beam of light produced by a laser can weld metals. 激光器發(fā)生的光束可以銲接金屬。 返回 all-weld-metal
