Study on the structure of the alloy welding mold and the welding specifications

摘要

ordinary carbon steel hardness and life is difficult to achieve blanking dies and drawing dies requirements. In the surfacing alloy steel and alloy steel base can improve the surface hardness and durability of the mold. To reduce the use of electric arc welding carbide decomposition and burn in the shielding gas. Welding mold base structure to meet the requirements of the welding. Mold heat treatment after welding specifications and hardness to meet the processing requirements and use of strength requirements. Welding process design mold substrate heating requirements and the requirements of the solder layer thickness and the thickness between layers allocation.
