锅炉安装中焊接工作承担了绝大多数的承压元件的连接。在小型锅炉安装中由于工作周期短,流动性大,工作量小等条件影响,焊接质量往往不能象制造厂那样得到严格监督,因而造成焊接质量差直接影响锅炉正常运行的情况。1 安装工地易出现的问题1.1 原材料入库前未按国家标准进行检验,只凭供应单位提供的质量保证书作数量和外观检查,不对质保书是否和材料一致进行检查。对于无质保书或质保书与实物不相合者不作处理。
The welding work in boiler installation undertakes the connection of most pressure components. Due to the short working period, high fluidity and small workload in the installation of small boilers, the quality of welding often can not be strictly supervised by the manufacturer, resulting in poor welding quality that directly affects the normal operation of the boiler. 1 easy to install the site problems 1.1 raw materials storage before the national standard test, only the quality assurance provided by the supplier for the number and appearance of the inspection, the quality of the book is not consistent with the inspection materials. For no warranty or warranty book does not match with the physical treatment.
