3. Before welding, the plug must be tightened

32. The two ends of the weld should be welded first, and the isothermal skin should be applied before welding the gaps in the middle. This process should be repeated layer by layer. Except for the first and last layers, the oxide skin should be cleaned as much as possible. When the alloy is fully cooled to the following temperature, use the head to cut gently to make the weld more stable. 3.3. Wear is not allowed There are arc pits: This kind of defect is easy to cause cracks. It is recommended to use T427 or T07 welding rod with a spot diameter of 3 mm. The DC power supply must be reversed, that is, 1 part is the pole, the current is small until the coating turns red,
3.5 When the voltage is low, the electrode head should be 2-3 meters away from the workpiece. 4 Marking to wwW.bzxz.Net
