There are several requirements that need to be paid attention to during the processing of stainless steel 45° elbow. After finishing the stainless steel 45° elbow factory, the following 4 points are added and summarized.

　　1. In the process of processing stainless steel 45° elbows, the stainless steel 45° elbows are prevented from being heated and corroded, so the welding current cannot be too large.

　　2. After welding, the hardness of stainless steel 45° elbow will increase. At this time, it will easily have cracks. If you use the same type of stainless steel to process stainless steel elbow, you should use 300 degrees Celsius for a long time. The above temperatures are preheated, and after welding, cold treatment is performed at 700 degrees Celsius.

　　3. The titanium calcium type of the stainless steel 45° elbow can be used with AC and DC, because the stainless steel elbow is welded with AC, the penetration depth is shallow, and there will be redness, so we generally use DC power supply.

　　4. When welding stainless steel 45° elbows with the same type of chrome stainless steel electrode, it must be preheated at a temperature of 200 degrees Celsius, and then tempered at a temperature of 800 degrees Celsius.
