style="text-indent:25px">焊接加熱過(guò)程中要向接頭區(qū)域輸入很多熱量，對(duì)焊縫附近區(qū)域形成加熱和冷卻過(guò)程，這對(duì)靠近焊縫的熱影響區(qū)的組織性能有很大影響，從而引起熱影響區(qū)硬度、強(qiáng)度、韌性、耐蝕性等的變化。與焊縫金屬不同，焊接時(shí)熱影響區(qū)的化學(xué)成分一般不會(huì)發(fā)生明顯的變化，而且不能通過(guò)改變焊接材料來(lái)進(jìn)行調(diào)整，即使有些元素可以由熔池向熔合區(qū)或熱影響區(qū)粗晶區(qū)擴(kuò)散，那也是很有限的。因此，母材本身的化學(xué)成分和物理性能對(duì)熱焊接性具有十分重要的意義。工業(yè)上大量應(yīng)用的金屬或合金，對(duì)焊接熱過(guò)程有反應(yīng)，會(huì)發(fā)生組織和性能的變化。即使是一些不發(fā)生相變的純鋁、純鎳、純鉬等，經(jīng)過(guò)焊接熱過(guò)程的影響，也會(huì)由于晶粒長(zhǎng)大或形變硬化消失而使其性能發(fā)生較大變化。嘉定區(qū)焊接技術(shù)改造</p></p><br
