The content of the welding inspection weld penetration microscope includes the materials, tools, measuring weld penetration microscope equipment, process and finished product quality inspection used throughout the production process from drawing design to product production. The seam welding penetration measurement microscope is divided into three stages: pre welding inspection, inspection during the welding process, and inspection of the finished product after welding. The inspection methods for welding penetration of pressure vessels can be divided into destructive inspection and non-destructive inspection based on whether they cause damage to the product. There are two types of welding penetration inspection for steel boiler pipelines: destructive inspection and non-destructive inspection

1) Pre welding inspection, penetration depth and width analyzer

2) Inspection of weld depth and width during welding process

3) Inspection of finished products after welding using a computer-based depth measurement microscope

4. Appearance inspection, welding penetration depth measurement

5. Effective penetration depth of weld seam for density inspection
