In the production of stainless steel storage tanks, stainless steel welding should be mostly argon arc welding, which is generally manual welding. The temperature should be controlled below 100 degrees, of course, the welding materials used should be matched, otherwise the welding effect will be affected. To avoid hot cracks during welding, hydrogen electrodes with low carbon content should be selected, the arc crater should be filled in the welding type, and the arc should be closed slowly to form a crescent-shaped arc. The time interval of arc extinguishing should be well grasped. Its use is subject to the following regulations:
1. Brush the edges and corners of the stainless steel tank several times to ensure that the thickness of the coating meets the design requirements.
2. Working at heights must pay attention to information security and establish a scaffolding and scaffolding. It is not necessary to clean frequently; the sedimentary substances in the water can be discharged only by opening the drain valve at the bottom of the tank regularly. The scale can be cleaned once every 3 years with simple equipment.
3. The defect repair technology in the tank can be found in the on-site management and construction safety inspection, and the analysis and maintenance can be carried out in time. The method is to use sandpaper, grinding wheel will leak or thin coating position information and economic radiation around five centimeters of coating in rough, and then repaint by repainting. Data leakage and thickness inspection are carried out after curing, and it can be used correctly until the inspection is qualified and normal.
4. Stop using stainless steel storage tanks in bad weather until the weather returns to normal.
