When eliminating the weld stress, the designated area needs to be heated to high temperature (600℃ ). The current heating method uses natural gas as raw material and uses a torch for heating to achieve the effect of stress relief.
现有技术中，采用火炬加热的方式，可以方便地对待加热产品的不同形状和位置进行加热处理，但在加热过程中，天然气在空气中燃烧，对筒体焊缝的加热时，由于空气流通、环境温度等原因影响，导致对焊缝的加热效率较低，延长加热时间，造成能源浪费很大，产生的二氧化碳、二氧化硫等废气较多，不符合目前环境要求和碳中和等要求。In the existing technology, torch heating is used to easily heat different shapes and positions of the products to be heated. However, during the heating process, natural gas burns in the air. When heating the cylinder weld, due to the air circulation , ambient temperature and other factors, resulting in low heating efficiency of the weld, prolonged heating time, resulting in a large waste of energy, and the generation of more waste gases such as carbon dioxide and sulfur dioxide, which does not meet current environmental requirements and carbon neutrality requirements.
为解决上述问题，申请人提出一种采用柔性电加热片对焊缝进行加热的方式，具体是将柔性电加热片覆盖待加热区域上，通过热传导的方式将热量传递至待加热区域表面，从而实现对产品的加热处理，消除焊缝应力。采用上述加热方式时，为了让柔性电加热片与待加热区域的表面更好地贴合和固定，进一步提高加热效率，因此提出一种焊缝加热支撑装置。In order to solve the above problem, the applicant proposed a method of using a flexible electric heating sheet to heat the weld. Specifically, the flexible electric heating sheet covers the area to be heated and transfers the heat to the surface of the area to be heated through thermal conduction, thereby Realize the heating treatment of the product and eliminate the stress of the weld seam. When using the above heating method, in order to better fit and fix the flexible electric heating sheet to the surface of the area to be heated and further improve the heating efficiency, a welding seam heating support device is proposed.
