焊条是压力容器、管道安装中常用的重要材料。其质量直接影响焊接质量，是焊接质量的基础和先决条件。现介绍几种检验焊条质量的简易方法。１　外观检查外观质量从某些方面反映了焊条的质量。（１）焊条药皮表面应平整，无损伤；药皮应均匀紧密地包在焊芯周围，引弧端药皮应倒 Electrodes are pressure vessels, pipe installation, an important material commonly used. The quality of a direct impact on the quality of welding, welding quality is the foundation and prerequisite. Now introduce several simple methods of testing the quality of the electrode. Appearance Inspection Appearance quality reflects the quality of the electrode in some ways. (1) the surface of the electrode coating should be smooth, no damage; coating should be evenly wrapped around the welding core, the arc side of the drug should be down
