因压型铝板具有质轻、高强、色泽丰富、施工方便、抗震、防火、防雨、寿命长、免维护等特点，现已被推广应用。还被广泛应用于各种焊接结构产品中，然而在焊接过程中会遇到一些现象。这就要求我们在焊接的时候注意一些问题。下面铝板生产厂家就压型铝板焊接时的常见问题做下具体介绍：
The profiled aluminum plate has been widely used because of its light weight, high strength, rich color, convenient construction, earthquake resistance, fire protection, rain protection, long service life, maintenance free and other characteristics. It is also widely used in various welded structural products. However, some phenomena will be encountered in the welding process. This requires us to pay attention to some problems during welding. The following is a detailed introduction to the common problems of profiled aluminum plate welding by the aluminum plate manufacturer:
1.合金表面容易出现难熔的氧化膜。
1. Refractory oxide film is easy to appear on the alloy surface.
2.焊接接头出现软化，强度系数较低。
2. The welded joint is softened and the strength coefficient is low.
3.铝合金热导率大（约为钢的4倍），相同焊接速度下，热输入值大。
3. The thermal conductivity of aluminum alloy is large (about 4 times that of steel), and the heat input value is large at the same welding speed.
4.压型铝板焊接时容易产生气孔。
4. It is easy to produce air holes when the profiled aluminum plate is welded.
5.焊接易产生热裂纹。
5. Welding is easy to produce hot cracks.

6.压型铝板线膨胀系数大，容易出现焊接变形现象。
6. The profiled aluminum plate has large linear expansion coefficient and is prone to welding deformation.
此外您在选择压型铝板的时候好货比三家，不同厂家生产的材质不同，通过相互比较，选择合适的铝材。其实，货比三家方式是简单的方式，不过比较的不是铝材的价格，而是质量、服务等各个方面，选择适合的铝材，满足使用需求。
In addition, when you choose profiled aluminum plate, you can compare three good products. Different manufacturers produce different materials. Through comparison, you can choose the appropriate aluminum material. In fact, it is a simple way to compare three stores. However, the comparison is not the price of aluminum materials, but the quality, service and other aspects. Select the appropriate aluminum materials to meet the use needs.
质量是选择压型铝板的重点，如何判断压型铝板的质量，主要是从工艺、性能等方面。压型铝板如果工艺看起来很粗糙，那该铝卷的质量存在问题，因此在选择的时候不能选该种的材质，否则不能满足其使用需求，无法制作成需要的物品。
Quality is the key to select profiled aluminum plate. How to judge the quality of profiled aluminum plate is mainly from the aspects of process and performance. If the process of profiled aluminum plate looks very rough, the quality of the aluminum coil has problems. Therefore, the material cannot be selected when selecting, otherwise it cannot meet its use needs and cannot be made into required articles.
