　　通风空调系统的重要组成部分，大部分由风道处理设备(如风道线)构成。然而，由于种种原因，可能会导致风管加工设备从风管出问题。

　　An important part of ventilation and air conditioning system, most of which is composed of air duct processing equipment (such as air duct line). However, due to various reasons, it may cause problems in the duct processing equipment from the duct.

　　1. 各类板材、管材必须有质量证明文件(包括出厂证明、质量证书、检测报告)和产品清单。

　　1. All kinds of plates and pipes must have quality certificates (including factory certificates, quality certificates, test reports) and product lists.

　　2. 成品风道内不得有变形、变形、开裂、孔洞、法兰脱落、开焊、缺铆接、缺螺栓孔等缺陷。

　　2. There shall be no deformation, deformation, crack, hole, flange falling off, open welding, lack of riveting, lack of bolt hole and other defects in the finished air duct.

　　3、阀体内安装消声器、罩体、风口等部件应检查调节装置是否灵活，漆膜、漆膜是否损坏。

　　3. If the muffler, cover, air vent and other parts are installed in the valve body, check whether the regulating device is flexible and whether the paint film and paint film are damaged.

　　4. 安装材料:螺栓、螺母、垫圈、垫片、密封条、自攻螺钉、拉丝铆钉、焊条、各种帆布、无纺布、射钉、山东风道膨胀螺栓等，应符合产品质量要求。

　　4. Installation materials: bolts, nuts, washers, gaskets, sealing strips, self tapping screws, drawing rivets, welding rods, various canvas, non-woven fabrics, shooting nails, Shandong air duct expansion bolts, etc., which shall meet the product quality requirements.

　　通风管道是目前国内市场发展较快、种类较多的一种管道。由于其自身的特点和优点，得到了越来越广泛的应用。为保证使用，根据本工程的要求，对用这些材料制作的风管提出了不燃或不燃B1灭火性能的要求。山东风管只要在风管加工过程中有质量保证，就能发挥风管的作用，使客户在使用时能达到预期的效果，真正做到满意服务。对一些常见的通风管道,如板料法兰通风管、管、胶表面和内部热绝缘材料,复合材料是基本条件之一,此外,热胶带已经依赖于热熔胶的优势,不加热,胶在室温下是,可靠的粘接强度。

　　Ventilation pipe is a kind of pipe with rapid development and many kinds in domestic market. Because of its own characteristics and advantages, it has been more and more widely used. In order to ensure the safety of use, according to the requirements of the project, the requirements of non combustible or non combustible B1 fire extinguishing performance are put forward for the air ducts made of these materials. As long as Shandong air duct has quality assurance in the process of air duct processing, it can play the role of air duct, so that customers can achieve the expected results in use, and truly achieve satisfactory service. For some common ventilation pipes, such as sheet flange ventilation pipe, pipe, glue surface and internal thermal insulation material, composite material is one of the basic conditions. In addition, hot tape has relied on the advantages of hot-melt adhesive. Without heating, glue is cured at room temperature, and reliable bonding strength.

　　铁板通风管道焊接容易产生气孔，下面为我们介绍气孔产生的原因及解决方法。

　　Iron plate ventilation pipe welding easy to produce porosity, the following for us to introduce the causes of porosity and solutions.

　　(1)焊丝延伸过长，保养气保养效果不好;

　　(1) The extension of welding wire is too long, and the effect of maintenance gas is not good;

　　(2)养护气罩选用不当，导致养护气对熔池的养护效果不佳;

　　(2) Improper selection of the curing gas cover results in poor curing effect of the curing gas on the molten pool;

　　(3)一代RMD焊接设备不具备早期送风功能，气体在引弧过程中不能及时维护。

　　(3) The first generation RMD welding equipment does not have the function of early air supply, and the gas cannot be maintained in time during the arc striking process.
