焊接前,第二道印花彩涂板容易产生裂纹。为什么会这样?所以我们要先了解裂缝产生的原因,找出原因,防止事故发生。
 
在电弧热作用下,印花彩涂板槽附近的锌层产生氧化(形成氧化锌)和蒸发,挥发白烟和蒸汽,容易在焊缝中产生气孔。焊接电流越大,锌蒸发越严重,气孔越敏感。钛、钙钛电极焊接时,在中电流范围内不易产生气孔。然而,采用纤维素电极和低氢电极焊接时,在小电流和大电流下容易产生气孔。此外,电极角度应尽可能控制在30°-70°之间。
 
其次,当采用弧焊印花彩涂板时,熔池附近的锌层在电弧热作用下氧化成ZnO并蒸发,形成大量的烟尘。因此,必须采取良好的通风措施。在同一焊接规范中,氧化钛电极产生的烟气量低于低氢电极。
 
最后,当彩涂镀锌板的焊接电流较小时,加热过程中形成的氧化锌不易逸出,容易造成氧化锌夹渣。ZnO的熔点为1800℃。大量的氧化锌夹渣对焊缝塑性有非常不利的影响。使用氧化钛电极时,ZnO细小均匀分布,对塑性和抗拉强度影响不大。采用纤维素电极或氢电极时,焊缝中氧化锌含量越来越大,焊接性能较差。

Before welding, the second printing color coated plate is easy to produce cracks. Why does this happen? So we need to understand the causes of the cracks first to find out the causes, so as to prevent accidents.
 
Under the action of arc heat, the zinc layer near the groove of printing color coated plate produces oxidation (forming ZnO) and evaporation, and volatilizes white smoke and steam, so it is easy to cause pores in the weld. The higher the welding current is, the more serious the zinc evaporation is and the more sensitive the porosity is. When titanium and calcium titanium electrodes are used for welding, it is not easy to produce pores in the middle current range. However, when cellulose electrode and low hydrogen electrode are used for welding, pores are easy to be produced under low current and high current. In addition, the electrode angle shall be controlled within 30 ° - 70 ° as far as possible.
 
Secondly, when arc welding is used for printing color coating plate, the zinc layer near the molten pool is oxidized to ZnO under the action of arc heat and evaporates, forming a large amount of smoke and dust. Therefore, good ventilation measures must be taken. In the same welding specification, the amount of smoke produced by titanium oxide electrode is lower than that of low hydrogen electrode.
 
Finally, when the welding current of the color coated galvanized sheet is small, the ZnO formed in the heating process is not easy to escape, which is easy to cause ZnO slag inclusion. The melting point of ZnO is 1800 ℃. The large ZnO slag inclusions have a very adverse effect on the weld plasticity. When titanium oxide electrode is used, ZnO is fine and evenly distributed, which has little effect on plasticity and tensile strength. When cellulose electrode or hydrogen electrode is used, the ZnO in the weld is larger and more, and the weld performance is poor.
