1. 技術背景,在焊接接頭中由于焊接所引起的各種裂紋，統稱焊接裂紋。焊接裂紋在焊縫金屬與熱影響區中都可能產生，是焊接凝固冶金和固相冶金過程中產生為危險的一種缺陷。焊接結構產生的破壞事故大部分都是焊接裂紋所引起的。隨著現代工業的發展，焊接結構也趨向大型化、大容量和高參數發展。有的推薦風管在低溫、腐蝕介質下工作，也有的在高溫高壓下工作，廣泛都用到各種高合金鋼、不銹鋼，以及種種合金材料。這些材料往往都對裂紋十分敏感，而裂紋卻又是大多重大事故的誘因，必須十分重視。焊接裂紋種類繁多，產生的條件和原因各不相同。有些裂紋在焊后立即產生了，有些風管廠家在焊后(hou)延續一(yi)定時間再(zai)產生，甚至在使(shi)用過程(cheng)中，在一(yi)定的外界條件(jian)誘(you)發下(xia)再(zai)產生。裂紋(wen)既出現在焊縫(feng)和熱影(ying)響(xiang)區表面，也產生在其內(nei)部。它對焊接結構的危害有(you)以下(xia)幾點。
