为了克服焊缝中氢的扩散和聚集而引起的脆变和延迟裂纹,而氢是来自焊条、焊剂的水份含量,设计焊条、焊剂的烘焙设备,使焊条、焊剂所含水份不超过0.1％,从而保证焊缝质量。由冶金部建筑研究总院和温州市焊接设备厂共同研制的采用远红外线加热的程控焊条烘干箱和吸入式焊剂烘干机。于1986年9月17～21日,通过了由冶金部建筑研究总院主持的技术测试鉴定会。程控焊条烘干箱,型号是DH—20、40、60、100、500 Kg级的系列产品,该产品采用程控转换。获使烘箱炉腔加热至350～400℃恒温两小时后,再自动降温至120℃,并长期保持在120℃工作的特点。吸入式焊剂烘干机,型号是YJJ—100、
In order to overcome the hydrogen diffusion and aggregation in the weld caused by the embrittlement and delayed cracking, and hydrogen from the electrode, the flux of water content, the design of welding rod, flux baking equipment, so that the electrode, flux moisture does not exceed 0.1 %, In order to ensure the quality of the weld. By the Ministry of Construction and Research Institute of Metallurgical Building, Wenzhou City, and welding equipment jointly developed by far-infrared heating of the electrode-controlled drying oven and suction flux dryer. In September 1986 September 21 ~ 21, adopted by the Ministry of Metallurgical Construction Research Institute presided over the technical testing appraisal. Programmable electrode drying box, model DH-20,40,60,100,500 Kg-class products, the program uses program-controlled conversion. The oven cavity is heated to 350 ~ 400 ℃ thermostat for two hours, and then automatically cooled to 120 ℃, and long-term maintained at 120 ℃ work characteristics. Inhalation flux dryer, model is YJJ-100,
