style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;white-space:normal;background-color:#FFFFFF;text-indent:2em;" align="center"> <img src="/uFile/90212/image/2019928152940748.jpg" alt="挖沙船的補焊工作如何展開?" title="挖沙船的補焊工作如何展開?" width="450" height="300" align="" /> </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;white-space:normal;background-color:#FFFFFF;text-indent:2em;"> 對挖沙船表面進行補焊主要是為修復裂紋和補償磨損尺寸。挖沙船的表面大都是采用鋼結構，鋼的品種繁多其可焊性差異很大，這主要與鋼中的碳和合金元素的含量有關。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;white-space:normal;background-color:#FFFFFF;text-indent:2em;"> 一般來說含碳量越高，合金元素種類和數量越多，可焊性越差?？珊感圆钪饕冈诤附訒r容易產生裂紋，鋼的裂紋可分為焊縫金屬在冷卻時發生的熱裂紋和近焊縫區母材上由于脆化發生的冷裂紋兩類。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;white-space:normal;background-color:#FFFFFF;text-indent:2em;"> 熱裂紋只產生在挖沙船表面的焊縫金屬中，具有沿晶界分布的特點，其方向與焊縫的魚鱗狀波紋相垂直，在裂紋的斷口上可以看到發黑的氧化色彩。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;white-space:normal;background-color:#FFFFFF;text-indent:2em;"> 產生熱裂紋的主要原因是焊縫中碳和硫含量高，特別是硫的存在，在結晶時，所形成的低熔點硫化鐵以液態或半液態存在于晶間層中形成脆弱的夾層，因而在收縮時即引起裂紋。 </p> <p style="margin-top:0px;margin-bottom:0px;padding:0px;color:#333333;white-space:normal;background-color:#FFFFFF;text-indent:2em;"> 冷裂紋主要發生在近焊縫區的母材上，產生冷裂紋的主要原因是鋼材的含碳量增高，其淬火傾向相應增大，母材近縫區受焊接熱的影響，加熱和冷卻速度都大，結果產生低塑性的淬硬組織。另外焊縫及熱影響區的含氫量隨焊縫的冷卻而向熱區擴散，那里的淬硬組織由于氫作用而碳化，即因收縮應力而導致裂紋產生。 </p> <p
