The required performance of welding for corrosion resistant overlay on tube plate with no defects such as incomplete fusion and bead crack etc.

通过对管板耐蚀堆焊进行层层试验,严格控制焊接线能量,减小母材熔深,尽可能降低熔合比,避免稀释率过高,以及选用高铬镍的焊接材料作为过渡层,制定出焊接工艺规程:完全能够满足堆焊金属的性能要求,避免未熔合及弧坑裂纹等缺陷的产生。

In order to prevent incomplete fusion,some measures should be adopted,such as using proper welding parameters,appropriate welding angle,assuring the swing range of electrode wire,confirming the welding layer number depending on the thickness of base metal and making multilayer and more bead as possible.

未熔合现象是CO2气体保护焊中最常见、危害性大且不易被发现的缺陷,约占缺陷总数的60%。
