鋁板生產(chǎn)成本較低,可以投入使用的管道,管道用于家庭生活現(xiàn)在聚乙烯塑料管,這個(gè)管道的長(zhǎng)期使用會(huì)對(duì)身體帶來(lái)危害,如果是使用鋁板,不是管道的內(nèi)壁,生產(chǎn)規(guī)模,帶來(lái)了人們身體的健康,帶來(lái)生活保障。鋁板生產(chǎn)廠家復(fù)合鋁板-低碳鋼鋁板的內(nèi)襯是6082鋁板。它是低碳鋼。在焊接過(guò)程中，與鋼管相比，鋁被制成鋁板。
　　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.
　　復(fù)合管底座與復(fù)合管襯套的密封屬于不同金屬的焊接;鋁板管與復(fù)合管襯管的背焊屬同一金屬的焊接;鋁板管與復(fù)合管底座的填充焊是一種不同金屬的焊接。

　　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，各種焊接材料和焊接工藝的選擇是由復(fù)合管的襯管、基材和鋁板材料決定的。2.1焊接方法和坡口設(shè)計(jì)采用常規(guī)氬弧焊方法，內(nèi)襯和過(guò)渡層采用TIG焊，基材采用焊條電弧焊，保證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.
　　由于底座和襯板之間沒有熔焊，所以在裝配前必須密封。襯墊厚度只有2.0毫米,所以選擇Φ薄線1.2毫米。密封通道是鋁板與碳鋼的連接，所以應(yīng)選用ER309焊絲，此焊絲主要用于異種鋼材的焊接，特別適用于碳鋼與鋁板的焊接。選擇根層焊絲。與密封層不同，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，許多國(guó)家已經(jīng)建立了的大規(guī)模生產(chǎn)生產(chǎn)線。目前，我國(guó)的產(chǎn)量仍相對(duì)較低，生產(chǎn)工藝不穩(wěn)定，且熱處理、酸堿火、冷軋管毛坯等。經(jīng)熱軋后的鋼坯符合西部鋼坯供應(yīng)標(biāo)準(zhǔn)。奧氏體鋁板是由相同的材料作為純鋁板和管。鋁板生產(chǎn)廠家復(fù)合管底座為6082。鋁板的焊接——碳鋼復(fù)合管與鋁板管的焊接可以看作是兩種焊接工藝的結(jié)合:即鋁板與鋁板的焊接;鋁板與碳鋼的焊接。
　　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.
