电容放电焊（ＣＤＷ）是一种快速凝固连接工艺，由美国矿业局开发，用于焊接不产生平衡显微组织的部件。ＣＤＷ产生高可靠性的焊接，不会形成引起脆性的金属间化合物，也不会产生焊区气孔，其有潜力降低成本并易于实现自动控制。在ＣＤＷ工艺中，被焊部件作为两极。阴极通常为 Capacitive discharge welding (CDW) is a rapid solidification bonding process developed by the U.S. Bureau of Mining to weld parts that do not produce a balanced microstructure. CDW produces highly reliable welds that do not form intermetallic compounds that cause brittleness and do not create weld pocket porosity that has the potential to reduce costs and ease of automated control. In the CDW process, the part being soldered acts as a bipolar. The cathode is usually
