My foreman insisted I use a different technique on a tricky flange weld
He said to run a smaller root pass and keep the heat lower than I normally would. Did it on a 12-inch steam line last week and the X-ray came back perfect, zero defects. Anyone else have a boss give you advice that seemed weird but totally worked?

Honestly that just sounds like good welding practice to me. A smaller root pass with less heat on a thick flange is pretty standard for avoiding burn-through. It's not some secret trick, it's just the right way to do the job. Maybe your normal method was just a bit too hot for that joint.

Ever have a foreman tell you to do something that just felt wrong in your gut? Mine had me switch to a totally different filler rod on some stainless pipe, and I was sure it was gonna sugar up. But the bend tests were flawless.

Oh man, my gut is wrong so often it should probably see a doctor. I've argued against back-stepping on thin aluminum, been sure a weld was too cold, you name it. My foreman will just nod, let me do it my way, and then the x-ray shows a line of porosity. It's humbling. Sometimes they just know the weird specifics of that one metal batch or joint setup.
