铝板生产成本较低,可以投入使用的管道,管道用于家庭生活现在聚乙烯塑料管,这个管道的长期使用会对身体带来危害,如果是使用铝板,不是管道的内壁,生产规模,带来了人们身体的健康,带来生活保障。铝板生产厂家复合铝板-低碳钢铝板的内衬是6082铝板。它是低碳钢。在焊接过程中，与钢管相比，铝被制成铝板。
　　The production cost of aluminum plate is relatively low. The pipes that can be put into use are polyethylene plastic pipes used for family life. The long-term use of this pipe will bring harm to the body. If aluminum plate is used, it is not the inner wall of the pipe. The production scale will bring people's health and life security. The lining of composite aluminum plate - low carbon steel aluminum plate of aluminum plate manufacturer is 6082 aluminum plate. It's mild steel. In the welding process, compared with steel pipe, aluminum is made into aluminum plate.
　　复合管底座与复合管衬套的密封属于不同金属的焊接;铝板管与复合管衬管的背焊属同一金属的焊接;铝板管与复合管底座的填充焊是一种不同金属的焊接。

　　The sealing of composite pipe base and composite pipe liner belongs to the welding of different metals; the back welding of aluminum plate pipe and composite pipe liner belongs to the welding of the same metal; the filling welding of aluminum plate pipe and composite pipe base is a welding of different metals.
　　由此可知，各种焊接材料和焊接工艺的选择是由复合管的衬管、基材和铝板材料决定的。2.1焊接方法和坡口设计采用常规氩弧焊方法，内衬和过渡层采用TIG焊，基材采用焊条电弧焊，保证了施工的方便性和通用性。
　　It can be seen that the selection of various welding materials and welding processes is determined by the liner, base material and aluminum plate material of the composite pipe. 2.1 conventional argon arc welding method is adopted for welding method and groove design, TIG welding is adopted for inner lining and transition layer, and electrode arc welding is adopted for base material, so as to ensure the convenience and universality of construction.
　　由于底座和衬板之间没有熔焊，所以在装配前必须密封。衬垫厚度只有2.0毫米,所以选择Φ薄线1.2毫米。密封通道是铝板与碳钢的连接，所以应选用ER309焊丝，此焊丝主要用于异种钢材的焊接，特别适用于碳钢与铝板的焊接。选择根层焊丝。与密封层不同，根焊采用ER2520H0。
　　Since there is no fusion welding between the base and the lining plate, it must be sealed before assembly. The pad thickness is only 2.0mm, so choose Φ thin line 1.2mm. The sealing channel is the connection of aluminum plate and carbon steel, so er309 welding wire should be selected. This welding wire is mainly used for the welding of dissimilar steel, especially for the welding of carbon steel and aluminum plate. Select the root wire. Different from the sealing layer, er2520h0 is used for root welding.
　　目前，许多国家已经建立了的大规模生产生产线。目前，我国的产量仍相对较低，生产工艺不稳定，且热处理、酸碱火、冷轧管毛坯等。经热轧后的钢坯符合西部钢坯供应标准。奥氏体铝板是由相同的材料作为纯铝板和管。铝板生产厂家复合管底座为6082。铝板的焊接——碳钢复合管与铝板管的焊接可以看作是两种焊接工艺的结合:即铝板与铝板的焊接;铝板与碳钢的焊接。
　　At present, many countries have established professional large-scale production lines. At present, China's output is still relatively low, the production process is not stable, and heat treatment, acid and alkali fire, cold-rolled tube blank and so on. After hot rolling, the billets meet the supply standard of the western region. Austenitic aluminum plate is made of the same material as pure aluminum plate and tube. The composite pipe base of aluminum plate manufacturer is 6082. Welding of aluminum plate - the welding of carbon steel composite pipe and aluminum plate pipe can be regarded as the combination of two welding processes: the welding of aluminum plate and aluminum plate; the welding of aluminum plate and carbon steel.
