Material characteristics | welding cartoon illustration, dry goods are also romantic!

1. Welding rod is a metal strip that can be dissolved by heat

2. The flash of welding rod is generated between welding rod and base metal.

3. Semi automatic welding refers to automatic output welding wire and manual welding.

4. Semi automatic (flash) submerged arc welding refers to automatic output welding wire and manual welding.

5. Full automatic (flash) submerged arc welding refers to downward automatic submerged arc welding used in the factory. Such as the fabrication of welded H-section steel.

6. Summarize various welding knowledge and titles.

7. Full penetration butt welding (full butt welding / groove butt welding): make a groove at the butt joint of two connectors to realize the welding of complete connection.

8. The reason for making groove for full penetration butt welding (full butt welding / groove butt welding) is to avoid that when the steel plate is thick, the electric spark heat cannot reach the bottom of the steel plate and cannot be well fused with the bottom steel plate.

9. Double sided groove and single sided groove are shown in the drawing.

10. Fillet weld refers to the welding of molten metal with triangular section on the connecting plate when connecting the base metal vertically.

11. Fillet welds are shown in the drawing

12. In case of welding defects, welding can be carried out after fusion blowing.

13. If you want to find welding defects, you can carry out ultrasonic flaw detection. Use ultrasonic to pass through the welding part. If there are uneven places, the light will be reflected and displayed on the display screen.
