Can I learn the second guarantee? How long does it take to learn? Is there a company in Xi'an?

Second welding technique:
The joints that open the slopes of the slopes of vertical or tilted positions must be welded from bottom to top, and the plate docking and vertical welding of the slopes can be welded. The left welding method is adopted.
2. When the outdoor operation is greater than 1m/s, windproof measures should be adopted.
3. You must choose a reasonable welding order according to the structure of the welders.
4. The two ends should be set with appropriate arcs and arcs.
5. The dirt and splash of the spray in the hose should be cleaned frequently.
6. There is a slot of the slopes, especially the multi -welded cramps of thick plates. When swinging on the welding wire, it should be stopped on both sides of the slopes. The thickness of each layer of the sawtooth is not greater than 4mm to make the welded seams. Follow the melting.
7. According to the diameter of the welding wire, the welding wire conductive tuling is correctly selected. The length of the welding wire should be controlled within 10 times the diameter of the welding wire.
8. When welding the filament hose, it must be pulled, and it cannot be coated. Before welding, discharge the impaired gas in the gas pipe.
9. The pore diameter is increased after the conductive tuling is worn, causing the welding to not stable, and the conductive tuling needs to be replaced.
