WELDING METHOD INCLUDING CONTINUOUS WAVE WELDING AND PULSE WELDING FOR COMPONENT OF AN IMPLATABLE MEDICAL DEVICE

摘要

A component of an implantable medical device may include a first member, a second member, and a composite seam weld formed between the first member and the second member. In some examples, the composite seam weld includes a continuous wave (CW)-welded portion formed using CW welding and a pulse-welded portion formed using pulsed welding. A first end of the pulse-welded portion may partially overlap a first end of the CW-welded portion and may be offset from the first end of the CW-welded portion in a direction substantially perpendicular to a longitudinal orientation of the first end of the CW-welded portion. Techniques for forming composite seam welds are also described.
