Summary
[edit]DescriptionTIG weld etch zone closeup.jpg |
A closeup micrograph of a TIG weld etch zone on 6061 aluminium (pulsed at 200 amps peak current, 5 amps sustain current, 50% pulse duty cycle, AC, 65% electrode negative, pure argon shield gas). These intentionally suboptimal conditions produce an widened etch zone where the normal layer of aluminium oxide has been removed from the surface, leaving exposed metallic aluminium capable of being welded. Image is approximately 10mm across the field of view; photographed with a Wild M5Z microscope and a Konica-Minolta Dimage X1 digital camera by W.S. Yerazunis. |
