A:A: Full welding results in stronger connections but also makes parts more susceptible to deformation. Partial welding offers weaker connections than full welding but results in less deformation. We choose between full welding and partial welding based on the application location. Full welding is used for the base plate and mold frame, while partial welding is used for other locations.
A:A: Currently, neither the heat treatment nor the material can achieve that.
A:A:The total carburizing time is approximately 8 hours, with a carburizing depth of 1-1.2 mm.
A:A：The mold cannot be carburized as a whole because the material will become brittle after carburizing. The base plate, surrounding plates and other parts that increase the strength of the mold frame cannot be carburized.
A:A:The nitriding process has never been used, and there is currently no data available.
A:A:Q355 can be achieved through optimized heat treatment processes.
