Dear all
I”ll send temporary report about welding efficiency up trial(OD31.8 mm X 6.3 mm)
-trial already finished (11/28 20:00)
-result(tried three items for welding efficiency up)
-impeder extension -> some effect(welding efficiency up about 8.1 %,but under estimation)
-spatter sheet -> no effect (teared up after used)
-cupper shield -> no effect(welding efficiency down about 41.5 %,down over estimation)
Analysis of each items->later
Today schedule -> external impeder trial (OD42.7mm X WT 6.3mm )
Thank you for your cooperation.
