焊接彩涂卷的要点有哪些？

面对不同的生产需要，彩涂板的使用要求也不同。一般情况下，根据客户需要焊接板材，并焊接成不同尺寸状态以供使用。焊接过程中需要了解以下预防措施。焊接质量的好坏将直接影响板材的后续使用效果。

焊接 彩涂板的要点是什么？
1、 打开相应的电源
耐用 彩涂板一般采用垂直外特性电源，直流采用正极性，焊丝接负极。一般适用于相应规格薄板的焊接，具有焊缝成形美观、焊接变形小的特点。使用的保护气体是纯度极高的氩气。焊接彩涂线圈的电流和氩气流量在规定范围内。
2、 把握大小
钨电极从气体喷嘴伸出的长度有一个合适的范围，这应该首先理解。角焊、深槽等屏蔽性差的地方有尺寸规定，管口到工件的距离也应控制在相应范围内。焊接彩涂线圈的弧长，在焊接普通钢材和焊接质量高的彩涂线圈时，应掌握相应的距离。太长或太短都是错误的。
3、 清洁并控制温度
为防止焊接气孔的发生， 彩涂板的焊接部位如有锈蚀、油污等必须清洗干净，为了用氩保护好熔池，便于焊接操作，钨极线与焊接部位的工件一般应保持规定的角度，填充丝与工件表面的夹角应尽可能小，一般为零度左右。
以上是 彩涂板焊接的关键点。同时，为了防止底部焊道的背面质量受到氧化的影响，有必要使用气体保护来保护彩色涂层辊。同时，为了避免在焊接彩色涂层线圈时出现焊接孔或气泡，在焊接过程中应严格遵守相应的规则和要求。

In the face of different production needs, the requirements for the use of color coated coils are also different. Generally, the plates are welded according to the needs of customers and welded into different size states for use. The following precautions need to be understood during welding. The quality of welding will directly affect the subsequent use effect of plates.

What are the key points of welding color coating?
1、 Turn on the appropriate power supply
Generally, the durable color coating coil adopts the power supply with vertical external characteristics, the positive polarity is adopted in DC, and the welding wire is connected to the negative pole. It is generally suitable for the welding of thin plates of corresponding specifications, with the characteristics of beautiful weld formation and small welding deformation. The shielding gas used is argon with very high purity. When the current and argon flow of welding color coating coil are, they should be within the specified range.
2、 Grasp the size
The length of the tungsten electrode protruding from the gas nozzle has a suitable range, which should be understood first. There are size regulations in places with poor shielding such as fillet welding and deep grooving, and the distance from the nozzle to the work should also be controlled in the corresponding range. The arc length of welding color coated coil, the corresponding distance should be mastered when welding ordinary steel and color coated coil with high welding quality. It is wrong to be too long or too short.
3、 Clean and control the temperature
In order to prevent the occurrence of welding pores, the welding parts of color coated coil must be cleaned if there is rust, oil stain, etc. In order to protect the welding pool well with argon to facilitate the welding operation, the tungsten electrode line and the workpiece at the welding position shall generally maintain the specified angle, and the included angle between the filler wire and the workpiece surface shall be as small as possible, generally about zero degrees.
The above are the key points of welding the color coating roll. At the same time, in order to prevent the back quality of the bottom weld bead from being affected by oxidation, it is necessary to use gas protection to protect the color coating roll. At the same time, in order to avoid welding holes or bubbles when welding color coated coils, the corresponding rules and requirements should be strictly observed during welding.
