產品介紹
鑄鋼件(jian)的電(dian)弧(hu)冷(leng)焊(han)(han)(han)法(fa)具有設備(bei)簡單、焊(han)(han)(han)前工件(jian)不(bu)用加溫、焊(han)(han)(han)后工件(jian)變形(xing)較小、運用靈(ling)活、適應(ying)性強等優點，尤(you)其適用于大型(xing)復雜機件(jian)的焊(han)(han)(han)修。但電(dian)弧(hu)冷(leng)焊(han)(han)(han)時冷(leng)卻速(su)度快，工件(jian)受熱不(bu)均，極易形(xing)成白(bai)口和裂(lie)紋。
