灰口鑄鐵目前常以鑄件金巴黎彩票的形式運用于生產,由于鑄造工藝的特點,鑄件往往存在著各種不同程度的缺陷,在生產現場中也有許多因各種原因而損壞的鑄件。鑄鐵的焊接實際上就是對存有缺陷或者損壞的鑄件進行補焊。(冷焊機13821569773-盧昕)所以鑄件補焊具有很大的經濟意義。

4.2QIHANHANBUHUIKOUZHUTIEDEBUHANGONGYI:

氣焊火焰溫度比電弧溫度低得多,因而焊件的加熱和冷卻比較緩慢,這對防止灰口鑄鐵在焊接時產生的白口組織和裂紋都很有利。所以用氣焊焊補的鑄件質量一般比較好,因氣焊成為補焊鑄鐵的常用方法。但氣焊與焊條電弧焊相比,焊工的勞動強度高,焊件變形較大,焊補大型鑄件時難以焊透。但由于氣焊鑄件的質量較好,易切削加工,使許多工廠中的中小型灰口鑄件,還是較多用氣焊焊補。
