电火花检验是对钢结构涂层质量的一种有效检验方法,但钢结构有限空间内较难进行有效的电火花涂层检验,故研究了一些用于有限空间电火花涂层检验的方法和设备,并已申报发明专利。

Electric-spark is an effective method to test the quality of steel coating,but it's hard to detected by electric-spark for confined spaces of steel structure,so coating detected by electric-spark of confined spaces of steel structure researched,including method and device,and the invention patent was applied.
