I didn’t know that, thanks for the tip!
Good tip! I wish I had heard that before. It would have saved me some time with the oxy acetylene torch.
I’ll have to remember that. No more BFH adjustments.
Would this also work for welding a base plate that will be lagged to the floor?What size hole ?
I watched the videos on weld distortion. This seems to track with what I learned from them. The heat of welding the flange to the stantion expands the flange but the metal at the center (with no hole) has no place to go. The metal is soft, it expands and it bulges. It doesn’t go back to flat as it cools.
With the hole there the metal isn’t there to go through the soften, expand, bulge cycle. The flange doesn’t get distorted.
Watch those videos!
