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。有的推薦不銹鋼通風管在低溫、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，有些不銹鋼通風管批發在(zai)(zai)焊(han)(han)后延(yan)續一定(ding)時間(jian)再產生，甚至在(zai)(zai)使用過程中，在(zai)(zai)一定(ding)的(de)外界條件誘發下再產生。裂紋既(ji)出(chu)現在(zai)(zai)焊(han)(han)縫和熱影(ying)響區表面，也產生在(zai)(zai)其(qi)內部(bu)。它對(dui)焊(han)(han)接結構的(de)危害有以下幾點。
