Overview

Experimental study demonstrates enhanced weld tensile strength and pass rates in tungsten-nickel assemblies, suggesting increased deuterium lamp durability.

Key Points

To optimize the manufacturing and welding process of tungsten-filament assemblies in deuterium lamps by overcoming defects caused by tungsten's refractory properties.
Introduced a pre-welding hydrogen-firing treatment alongside redesigned spot-welding electrodes and positioning fixtures.
Conducted welding operations under a protective hydrogen-nitrogen atmosphere and optimized operational parameters using an orthogonal experimental design.
Process optimizations produced consistent, qualitative increases in weld tensile strength and final product pass rates.
The integrated protocol successfully mitigated common manufacturing defects, significantly reducing post-weld misalignment, surface oxidation, and joint inconsistency.
