镀锌后的钢材能焊接吗?

  镀锌,又称镀锌和镀锌,是防止腐蚀和减少磨损的有效方法。将除锈后的钢构件浸泡在500℃左右的熔融锌溶液中,使钢构件表面附着在锌层上,起到防腐蚀的作用。随着冷镀锌钢管的禁用,热镀锌钢管迅速发展,热镀锌越来越多。

  Galvanizing, also known as galvanizing and galvanizing, is an effective way to prevent corrosion and reduce wear. After rust removal, the steel members are immersed in a molten zinc solution at about 500 ℃, which makes the steel members surface adhere to the zinc layer and plays an anti-corrosion role. With the prohibition of cold galvanized steel pipe, hot-dip galvanized steel pipe develops rapidly, and hot-dip galvanized steel pipe is more and more.

  只要焊接材料、焊接面、焊接电流、焊接速度、焊接方法等焊接条件适宜,镀锌钢板也可以焊接。

  As long as the welding conditions such as welding material, welding surface, welding current, welding speed and welding method are suitable, galvanized steel plate can also be welded.

  一般钢材的焊接强度不会减弱,但随着镀锌厚度的增加,合适的焊接条件范围变窄,使焊接难度加大,更好将焊接部位的锌完全去除。

  Generally, the welding strength of steel will not be weakened, but with the increase of galvanized thickness, the range of suitable welding conditions will be narrowed, making welding more difficult. It is better to completely remove the zinc from the welding part.

  镀锌钢板焊接时应注意以下几点:

  The following points shall be noted during the welding of galvanized steel plate:

  (1)焊接产生大量烟雾,焊接工人在吸入时会产生情绪上的不良影响,所以有必要戴口罩或安装排烟设备。

  (1) Welding produces a lot of smoke, which will have an adverse effect on the mood of the welding workers when they inhale, so it is necessary to wear masks or install smoke exhaust equipment.

  (2)焊后清除焊渣,锌层剥落部分用高锌漆或锌焊修复。

  (2) The welding slag shall be removed after welding, and the peeling part of zinc layer shall be repaired by high zinc paint or zinc welding.

  因此,焊接没有什么特殊的问题。但是,现场焊接总是对外观有害,所以尽量使用螺栓。

  Therefore, there is no special problem in welding. However, field welding is always harmful to appearance, so try to use bolts.

  热镀锌钢在这里焊接注意事项有,热镀锌钢管用于运输和施工,热镀锌钢是将钢、不锈钢、铸铁等金属浸在熔融液态金属或合金中获得镀层的一种技术。热镀锌是世界上应用更广泛的钢表面处理方法。

  The hot-dip galvanized steel is used for transportation and construction. The hot-dip galvanized steel is a kind of technology to dip steel, stainless steel, cast iron and other metals into molten metal or alloy to obtain coating. Hot dip galvanizing is the most widely used method of steel surface treatment in the world.
