焊接济南岗亭时需要注意哪些方面?

发表时间:2017-07-15 11:51  责任编辑:蓝翔岗亭  点击:

  济南岗亭在焊接的时候需要注意哪些事项呢?焊接技术被用于进行整个济南岗亭连接的时候,同时,这种不锈钢材质本身在焊接的时候对于焊接材料、焊接工艺等多方面皆有较高的要求。那么正确的焊接方法是怎样的呢?

  i'nan post needs to pay attention to what matters in the welding time? Welding technology was used for time, the Ji'nan post connected at the same time, the stainless steel material itself in welding for welding materials, welding process and other aspects have higher requirements. So what is the correct method of welding?

  1、济南岗亭过渡层的焊接采用反极性、直线运条和多道焊。

  1. The welding of transition layer of Ji'nan post adopts reverse polarity, straight line transmission and multipass welding.

  2、焊接不锈钢岗亭时,要严格按照评定合格的焊接工艺进行。

  2, welding stainless steel box, in strict accordance with the assessment of qualified welding process.

  3、为防止不锈钢岗亭的重复加热使焊缝的抗蚀性能降低,复层焊缝应在后焊接。

  3. In order to prevent the repeated heating of the stainless steel box, the corrosion resistance of the welding seam will be reduced, and the compound weld shall be welded in the end.

  4、合理选择过渡层的焊接材料,过渡层的填充金属必须能允许基层的稀释。

  4, reasonable choice of transition layer of welding materials, transition layer of filler metal must be allowed to dilute the base.

  5、济南岗亭在焊接基层时不得熔化复层,复层金属熔人基层焊缝会产生焊接裂纹。

  5, Ji'nan box in the welding of the base layer shall not melt layer, composite layer of metal welding seam will produce welding crack.

  6、为减少基层对过渡层的稀释,过渡层焊接应尽量选用小直径焊条,采用小电流、快速焊。

  6, in order to reduce the dilution of the base layer to the transition layer, the transition layer welding should use the small diameter welding rod as far as possible, and adopt the small current and the fast welding.

  7、基层钢板侧尽量选用抗裂性能较强的碱性焊条。

  7, the basic steel side as far as possible the use of crack resistance of the basic electrode.

  8、济南岗亭过渡层的熔焊金属在基层处的厚度宜为1。5~2。5mm,在复层处的厚度为 0。5~1。5mm。

  8, Ji'nan box transition layer of welding metal at the base of the thickness should be 1. 5~2. 5mm, the thickness at the cladding is 0. 5~1. 5mm.

  9、壳体复层焊缝表面应磨平,余高控制在0。5mm以下。

  9. The surface of the weld seam shall be polished and the remaining height shall be controlled at 0. 5mm below.

  10、济南岗亭复层的焊接应采用多道焊,层问温度控制在60℃以下。

  10, Ji'nan post repair layer welding should use multi-channel welding, layer temperature control below 60 degrees celsius.
