摘要
在石化工程建设施工过程中 ,恶劣天气是影响焊接质量的关键因素之一。恶劣天气使焊条受潮 ,坡口生锈 ,增加焊接金属中氢扩散机会 ,容易产生焊接缺陷 ,恶化焊接金属的机械性能。因此 ,要采取必要的防护措施并加强焊条的使用管理 。
The bad weather is one of the key factors that affect the quality of welding during petrochemical project construction.The atrocious weather makes the electrodes affected with damp,pipe ends bevel rusting and increase the hydrogen diffusion chance in welding metal and it is easy to produce welding defects and deteriorate the mechanic property of welding metal. Therefore,it is necessary to adopt preventive measures and strict control of electrode usage to insure the welding quality.
