Being a weld newb, can a weld look good but still be a shitty weld ie poor penetration?
What am I looking at that makes it weldporn?
100% Yes. Poor Root penetration is a big problem with guys who focus too hard on making their welds pretty rather than making the correct passes.
But there are many people who can make it work.
In general though, real welds I see on industrial pipe systems by guys who spend 12 hours a day welding, they don't give a fuck on how their cap pass looks, its simply of no consequence. As long as it doesn't have porosity, and ideally they won't have to grind it down too much if at all to get their cap height correct.
The biggest thing in piping for sure, is to make sure that you have full penetration and that the penetration does not impede the material in the pipe. Spec for penetration is that the height inside is uniform, and that the total inside height is not bigger than 3mm.
BIggest thing though which most people are so dumb about, stray arcs. If your stinger catches a piece of pipe, and I see it, you are cutting that piece of pipe out and starting new. ASME B31.3 has absolutely ZERO tolerance for stray arcs, doesn't matter what material, or procedure you are welding too, doesn't matter if its PWP7, PWP10, or even just a plain jane CWB structural weld. You better hope I can't find a stray arc.

Mental note: Never let Meme405 inspect my welds...
*edit* Back on track, I got the rally bug up on axle stands and started prepping for the Hagerty Silver Summit in Colorado. On Monday I leave for a 10-day, 6,300km road trip...so the car better be ready!
I'm curious about the stray arc thing? What does it do to the metal that makes it so awful? I haven't touched an arc welder since high school. I think my welds were just strays so closely put together they joined the metal? Haha
I'm guessing the reason you don't see pretty welds is because they are strictly for structural purposes. If he's welding a tank in a show car, versus some underground piping I sure hope it would be pretty as well.
Took my front calipers off at school and checked the pads, saw there was plenty of life left so I put them back on. As I was tightening down the bolts holding the caliper together the torque wrench I was using didn't click off. I had no idea how long it would take to get it properly torqued and just as I felt it start to tighten up (aka close to when the wrench would normally click off), the thing just gave out and launched my hands into the fender. Had to figure out how to replace the snapped bolt because I measured it as an M8x1.25 but it turned out the thread pitch was very slightly different than the M8x1.25 bolt I was given as a replacement. The new one wouldn't fit into the nut. Called NAPA and later found out they didn't have what I was looking for so I went to the VW dealer and learned the bolt isn't sold separately. I have to buy the whole caliper bracket which may take 3-4 days to get here. Having learned that I checked NAPA again and found they have aftermarket brackets which I'll probably end up buying instead, because I don't really want to risk leaving my car on jack stands out in Burnaby for the weekend.

where did you get that white board? thats so useful, ive been drawing on a piece of paper and sticking it to the windshield
Didnt know C63's ran on 94
Time to cut off some mufflers yet?

Agreed I don't see pretty welds because the welds I inspected were all done where quality and speed were the determining factors. If the weld was strong, and passed NDT (X-ray or hydrostatic testing) then that's good enough. Looking pretty isn't even a consideration. Now the problem is that for your pretty welds, while that welder is trying to maintain a beautiful bead and consistent dimes, he is not ensuring proper adhesion, or penetration. This depends on the procedure being welded to, and of course the skill of the welder, but believe me I have seen beautiful welded tanks, which fail catastrophically due to poor passes covered by nice welds.
Like I said there are those that can obviously do it, and they are immensely skilled, if it's your first time grabbing a welder, or if you only do it once in awhile, focus on adhesion and proper passes, rather than laying a nice bead. The nice bead will come with practice.
On the stray arc thing, it's all about the code, ASME (Used more in BC) and CSA (Used in the oil sands) both are critical on NO stray arcs. The reason being that a stray arc can change the metallurgy of a piece of steel at the very lowest level, it can leave stress cracks not visible to the human eye in that material, and the rapid heating and cooling of that material leaves a defect called Martensite (an area of very hard structure), this area is brittle and weak compared to the rest of the pipe, and has been proven to be very prone to failure at that area.
This all goes far beyond what you need to worry about for any weld on some catch can, or some welded nut on your car, but back to the original question, yes pretty welds can fail, and I've seen my fair share of beautiful welds fail X-Ray tests.

Right before we moved into the house a friend in Whistler renovated their kitchen. All the cabinets were the gloss-white finish you see. One day I tried a whiteboard marker on them...and oh my gosh, they are the best thing ever. The workbench at the other end of the shop has a full wall of them, very handy.
Finally got to do the coilover job on the e82 it took me forever (roughly 6-7 hours) mainly because of stupid mishaps
mishap #1
Spoiler!
The coils i bought was a used item with only 7k miles but unfortunately the thread were damage on the rear shocks lower mount (cross threaded)
Talk to the seller got a partial refund to order the damage parts
But its backordered so i went ahead and re-tap the thread
mishap #2
Spoiler!
Washer missing on the rear coils luckily i hoard some parts lol
hole modified
Can finally start lol
Started in the rear it was easy only have to remove 2 bolts underneath and one nut at the top
The part i hated to do was removing the trunk trim
Made a hole so i dont have to the remove the trim for next time and also easy access when i want to adjust stiffness on the shocks
Of to the front
I was taught that when working on something new and unfamiliar (suspension/brakes) always work and finish the one side first before starting on the other side. That way you can copy and compare that you did it properly . That lesson served me well in this situation being as there were so many sensors on this car!
The front had more steps but it was manageable
mishap #3
Spoiler!
Needed a special tool to spread the knuckle to access the shock
I couldnt wait one week and let the car hang loose on the jack stands so i just made my own
ALL done!
Opted to adjust the height added some anti sieze on the threads
NOW adjusting the rear really tested my patience big time lmao
It was so tight that i couldnt adjust the height
So i removed the big bolt on the lower control arm and the nut at the top( good thing i made that hole lol ) to have some slack .
Only had the left rear to do at this point and i thought it was gonna be smooth sailing WRONG...
mishap #4 the very last and the worst
Spoiler!
While removing the nut at the top of the shock tower it somehow fell in to a hell hole!
the 17mm nut , big ass washer , and the 17mm socket is now stuck on the wheel well with only that small access hole why bmw WHY
I was able to fish out the nut and socket via a magnet but the washer is bigger than the access hole. Only way out is through the top which the magnet couldn't handle.
I was finally able to pull it out via steel wire after
patient was the key! but that was a brutal 2-3 hours not fun at all.hah
And this would never be complete with out some battle scar .lol
Spoiler!
Even with all the mishaps the finish product was worth it.
Mishaps....part of the reason I started smoking again.
Nice work though, looks great!!!
If the spreader were a one-off job, instead of modifying a perfectly good socket, I would've suggested taking a bolt, double-nutting it and grinding the head to size. This also works when you have to remove drain/fill plugs and don't have the right socket.

Im very happy with the results!
Wow! Good work! End result looks very good!
Have you thought about adding some spacers? I am got 12.5mm on fronts it mades it just extra flush. I have 10mm for the rear but I was rubbing with 255s so had to give them up. But given how low you are riding, spacers may not work for you. Nice tuck anyways.
Sadly I can relate to mishap #4 happen. Very sad.
Those are big holes in the trunk liner to adjust the shocks :O
