My very first time doing welding and flux core. Any tips what i should work on?
I am currenty using a mastercraft flux core welding machine, my settings are max 2 amp. and wire speed is 6.
May material is 16 ga 1.5" 1.5" angle bar

I made a 14-minute 3D animation about weld inspection and wanted to share it here for feedback from people who actually do this work.
Setup: one 16 mm single-V butt weld plate with six defects planted on purpose: undercut, surface crack, hidden crack, porosity, slag and lack of fusion. Then nine methods against it: VT, dye penetrant, magnetic particles, eddy current, UT, phased array, radiography, macro etch and a hydraulic pressure test (1.5x rated, oil not air). Each method gets a score out of 6.
A few things that surprised me while researching:
• Eddy current on steel only really sees the surface, even though it works through paint.
• Radiography is great at volume defects but can miss tight, tilted flaws like lack of fusion.
• UT and phased array did best on flat internal defects (4/6 each), but no single method found everything.
• The pressure test proves the part holds, not that it's defect-free (0/6).
• Combining VT + MT + UT covers all six.
I'm not a certified NDT inspector, so I'd really like to hear where I got it wrong or oversimplified, and which test you'd add.

Did 3 fill passes then a 3 bead cap passed my bend test after cutting it with plasma torch and grinding it. Been welding for 7 months now

I’m in my sophomore year of high school and I’m in the welding class. I ran this with a 7018 and uphill on a 6” diameter pipe segment. Does my weld look good?

What am I doing wrong?😅

This is a little better

When you hire a couple of pigeons to weld your exhaust on

I left manual welding to now operate cobots and industrial robots, is it an advance? Is it a growth or in the end is it more of the same?

This is my first attempt at 3/8 v grove fillet in 1g position. How is it my tie in suck bit can I fill those in when I cap it.

Been pulse welding for about 8 months, lmk what you think

I stick/tig weld outside and inside, in different lighting scenarios. I usually rock the bigger viewing screen but am switching to a 2x4 for shits n giggles
What auto welding lens do yall recommend and why?
