When welding the isolation sleeve container of a magnetic pump at temperatures in the low tens of degrees below zero, what precautions should be taken?

A seal sleeve for a magnetic pump is to be designed; the temperature can range from -80 to 180 degrees Celsius, and the pressure resistance should be between 0.6 and 100 kilograms of pressure. It was already known that at normal to high temperatures, as long as the material thickness is appropriate, pressure resistance is not an issue. The problem is that the temperature can sometimes drop to several degrees below zero; so what should we pay attention to when welding the isolation sleeve containers?
Did I not describe it in enough detail, or was it posted in the wrong section?
