不锈钢可以是许多工程项目的首选钢材,但是当涉及到重型制造时,完全由不锈钢制造大型产品的成本可能成本过高。使用成本较低的碳钢(铁)制造非必要零件和框架有助于降低大型制造项目的总体成本。例如在高温或腐蚀区域使用不锈钢,然后将未指定区域与低碳钢匹配。将两种不同金属连接在一起的准备和计划需要一个经验丰富的不锈钢加工厂来确保正确完成。

如果焊接部件用于更高温度的服务,那么钢和填料的热膨胀率的差异可导致热疲劳开裂。在具有提高的铁素体水平的这些焊接温度下的长曝光时间可导致由于σ相形成而导致的脆化。
镍基填料(Inconel)产生的焊缝热膨胀率低于不锈钢填料,因此可能是优选的。

三、焊接风险和缺点

  1. 焊接成本增加。 焊接异种金属会给工艺带来额外的挑战。这转化为劳动力增加,拒绝/错误率和成本增加。
  2. 不锈钢的热裂纹。由于它比碳钢更耐电,因此不锈钢在电阻焊接中的加热速度比碳钢快得多。在等待碳钢达到焊接温度的同时,不锈钢会过热并且充满热裂纹。使用填料焊接或预热普通钢可以改善这种情况,但这些方法并不完美。
  3. 高温使用条件下的热膨胀。在焊丝形式中使用异种金属的另一个问题是热量的热膨胀会不同地影响每种金属。两种金属之间的膨胀率的这种差异可能导致焊接接头的额外疲劳 - 降低了线材的结构完整性和使用寿命。
  4. 增加双金属腐蚀。您通常希望使用不锈钢的原因之一是其耐腐蚀性强。未暴露的普通和不锈钢焊接暴露在极端腐蚀条件下,例如浸入盐水中,可能会导致腐蚀。这是因为普通钢颗粒与不锈钢合金的混合会损害不锈钢的保护性氧化层,从而形成锈蚀。
  5. 降低焊接强度。连接异种金属的问题在于,即使采用基于填料的焊接方法,也会导致焊缝变弱。仅焊接温度和操作公差的差异很容易损害焊接接头的强度。

四、焊条的选择
