因壓型鋁板具有質輕、高強、色澤豐富、施工方便、抗震、防火、防雨、壽命長、免維護等特點，現已被推廣應用。還被廣泛應用于各種焊接結構產品中，然而在焊接過程中會遇到一些現象。這就要求我們在焊接的時候注意一些問題。下面鋁板生產廠家就壓型鋁板焊接時的常見問題做下具體介紹：
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.合金表面容易出現難熔的氧化膜。
1. Refractory oxide film is easy to appear on the alloy surface.
2.焊接接頭出現軟化，強度系數較低。
2. The welded joint is softened and the strength coefficient is low.
3.鋁合金熱導率大（約為鋼的4倍），相同焊接速度下，熱輸入值大。
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.壓型鋁板焊接時容易產生氣孔。
4. It is easy to produce air holes when the profiled aluminum plate is welded.
5.焊接易產生熱裂紋。
5. Welding is easy to produce hot cracks.

6.壓型鋁板線膨脹系數大，容易出現焊接變形現象。
6. The profiled aluminum plate has large linear expansion coefficient and is prone to welding deformation.
此外您在選擇壓型鋁板的時候好貨比三家，不同廠家生產的材質不同，通過相互比較，選擇合適的鋁材。其實，貨比三家方式是簡單的方式，不過比較的不是鋁材的價格，而是質量、服務等各個方面，選擇適合的鋁材，滿足使用需求。
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.
質量是選擇壓型鋁板的重點，如何判斷壓型鋁板的質量，主要是從工藝、性能等方面。壓型鋁板如果工藝看起來很粗糙，那該鋁卷的質量存在問題，因此在選擇的時候不能選該種的材質，否則不能滿足其使用需求，無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.
