1. 技(ji)術背(bei)景,在(zai)(zai)焊(han)(han)(han)接(jie)(jie)接(jie)(jie)頭中(zhong)由于焊(han)(han)(han)接(jie)(jie)所(suo)引起的(de)各(ge)(ge)(ge)種裂(lie)紋(wen)，統稱(cheng)焊(han)(han)(han)接(jie)(jie)裂(lie)紋(wen)。焊(han)(han)(han)接(jie)(jie)裂(lie)紋(wen)在(zai)(zai)焊(han)(han)(han)縫(feng)金(jin)屬與熱影響(xiang)區(qu)(qu)中(zhong)都可(ke)能產(chan)生(sheng)(sheng)，是焊(han)(han)(han)接(jie)(jie)凝(ning)固冶(ye)金(jin)和固相(xiang)冶(ye)金(jin)過程(cheng)中(zhong)產(chan)生(sheng)(sheng)為(wei)危險的(de)一(yi)種缺陷。焊(han)(han)(han)接(jie)(jie)結構產(chan)生(sheng)(sheng)的(de)破壞(huai)事(shi)故大(da)部分(fen)都是焊(han)(han)(han)接(jie)(jie)裂(lie)紋(wen)所(suo)引起的(de)。隨著(zhu)現代工業的(de)發(fa)展(zhan)，焊(han)(han)(han)接(jie)(jie)結構也趨(qu)向大(da)型化(hua)、大(da)容量和高(gao)參數發(fa)展(zhan)。有(you)(you)(you)的(de)在(zai)(zai)低(di)溫、腐蝕介質下(xia)工作，也有(you)(you)(you)的(de)在(zai)(zai)高(gao)溫高(gao)壓下(xia)工作，廣泛都用到(dao)各(ge)(ge)(ge)種高(gao)合金(jin)鋼、不銹鋼，以及(ji)種種合金(jin)材料。這些材料往往都對裂(lie)紋(wen)十(shi)分(fen)敏(min)感，而裂(lie)紋(wen)卻又是大(da)多重大(da)事(shi)故的(de)誘因(yin)，必須十(shi)分(fen)重視。焊(han)(han)(han)接(jie)(jie)裂(lie)紋(wen)種類繁多，產(chan)生(sheng)(sheng)的(de)條件和原因(yin)各(ge)(ge)(ge)不相(xiang)同(tong)。有(you)(you)(you)些裂(lie)紋(wen)在(zai)(zai)焊(han)(han)(han)后立即產(chan)生(sheng)(sheng)了(le)，有(you)(you)(you)些在(zai)(zai)焊(han)(han)(han)后延續一(yi)定時間再產(chan)生(sheng)(sheng)，甚至(zhi)在(zai)(zai)使(shi)用過程(cheng)中(zhong)，在(zai)(zai)一(yi)定的(de)外界條件誘發(fa)下(xia)再產(chan)生(sheng)(sheng)。裂(lie)紋(wen)既出現在(zai)(zai)焊(han)(han)(han)縫(feng)和熱影響(xiang)區(qu)(qu)表(biao)面，也產(chan)生(sheng)(sheng)在(zai)(zai)其內部。它對焊(han)(han)(han)接(jie)(jie)結構的(de)危害有(you)(you)(you)以下(xia)幾點。

1．冷(熱)水機組的基本工作過程是：室外的制冷機組對冷(熱)媒水進行制冷降溫(或加熱升溫)，然后由水泵將降溫后的冷媒(熱)水輸送到安裝在室內的風機盤管機組中，由風機盤管機組采取就地回風的方式與室內空氣進行熱交換實現對室內空氣處理的目的。2．風管(道)式機組的基本工作過程是：供冷時，室外推薦不銹鋼通風管的制冷機組吸收來自室內機組的制冷劑蒸氣經壓縮、冷凝后向各室內機組輸送液體制冷劑。供熱時，室外的制冷機組吸收來自冷凝器的制冷劑蒸氣經壓縮后向各室內機組輸送汽體制冷劑，室內機組通過布置在天花板上的回風口將空氣吸入，不銹鋼通風管批發進行熱交換(huan)后送入安裝在室(shi)內各房間天花板中的風(feng)管(guan)(道)內，并通過出風(feng)口上的散流器向室(shi)內各房間輸(shu)送空氣(qi)(qi)。在風(feng)管(guan)(道)上設計有新風(feng)門和排風(feng)門，可以按(an)一(yi)定比(bi)例(li)置換(huan)空氣(qi)(qi)，以保證室(shi)內空氣(qi)(qi)的質量。
