佰富彩一般在印花彩钢板出现断裂现象时，或者需要多块钢板链接时，就需要对产品进行焊接处理，那么在焊接时我们需要注意什么呢：

佰富彩When there is a fracture phenomenon in the printed color steel plate, or when multiple steel plates need to be connected, it is necessary to weld the product. So what should we pay attention to when welding

1、印花彩钢板采用垂直外特性的电源，直流时采用正极性（焊丝接负极）。

1. The printed color steel plate adopts a vertical external characteristic power supply, and adopts positive polarity (welding wire connected to negative electrode) when DC is used.

佰富彩2、一般适合于6mm以下薄板的焊接，具有焊缝成型美观、焊接变形量小的特点。

2. It is generally suitable for welding thin plates below 6mm, with the characteristics of beautiful weld formation and small welding deformation.

3、保护气体为氩气，纯度为99、99%。当焊接电流为50-50A时，氩气流量为8-0L/min，当电流为50-250A时，氩气流量为2-5L/min。

3. The protective gas is argon, with a purity of 99 and 99%. When the welding current is 50-50A, the argon flow rate is 8-0L/min, and when the current is 50-250A, the argon flow rate is 2-5L/min.

佰富彩4、钨极从气体喷嘴突出的长度，以4-5mm为佳，在角焊等遮蔽性差的地方是2-3mm，在开槽深的地方是5-6mm，喷嘴至工作的距离一般不超过5mm。

4. The length of the tungsten electrode protruding from the gas nozzle is preferably 4-5mm, 2-3mm in areas with poor shielding such as fillet welding, and 5-6mm in areas with deep grooves. The distance from the nozzle to the working position generally does not exceed 5mm.

佰富彩5、为防止焊接气孔之出现，印花彩钢板焊接部位如有铁锈、油污等务必清理干净。

佰富彩5. To prevent the occurrence of welding pores, the welding area of printed color steel plates must be cleaned of rust, oil stains, etc.

佰富彩6、焊接电弧长度，焊接普通钢时，以2-4mm为佳，而焊接印花彩钢板时，以3mm为佳，过长则保护效果不好。

佰富彩6. The length of the welding arc is 2-4mm when welding ordinary steel, while 3mm is better when welding printed color steel plates. If it is too long, the protection effect is not good.

7、对接打底时，为防止底层焊道的背面被氧化，背面也需要实施气体保护。

7. To prevent oxidation on the back of the bottom weld bead during butt welding, gas protection is also required on the back.

8、为使氩气很好地保护焊接熔池，和便于施焊操作，钨极线与焊接处工件一般应保持80-85°角，填充焊丝与工件表面夹角应尽可能地小，一般为0°左右。

8. In order to effectively protect the welding pool with argon gas and facilitate welding operations, the center line of the tungsten electrode should generally maintain an angle of 80-85 ° with the welded workpiece, and the angle between the filling welding wire and the surface of the workpiece should be as small as possible, usually around 0 °.
