Mig Welding outside corner joints and testing them using the cut and etch test.
C25 gas was used along with .035 (.9mm) ER70s-6 wire.
Thermal Arc fabricator 252i welder (very finicky) was used.
Uphill single pass weld tested against 2 pass weld with downhill root pass.

MIG Techniques PUSH AND PULL Tested with Cut and Etch Macro
A good way to test for penetration is the cut and etch test.
If the test is done while the weld is still fresh on you mind, there is a lot that can be learned and welding technique can be adjusted and improved.
I used a lincoln electric power mig 210mp for the first welds with settings of 19 vol...
MIG Welding Settings and Techniques for Horizontal and Vertical uphill
In this video, I go over mig welding settings for short circuit mig welding in horizontal and vertical uphill. Also a quick tip for vertical uphill settings. Arc shots and techniques are shown in detail.
Short Circuit Mig Welding Compared to Dual Shield on Vertical Uphill
For Out of position welding like vertical uphill, Short circuit mig welding requires some manipulation of the gun to prevent excess convexity of the bead profile. Dual shield flux core is different. This video shows the distinct difference in speed and bead profile
