Space required for welding operations
Thread Content
The clearance between the two stiffeners is 300, with a depth of 450 – does this dimension provide enough space for welding operations? I’m not sure if it’s possible to weld blue welds.
It can be welded, but in practice a single-sided groove is created on the outside, allowing for single-sided welding that results in a double-sided finished surface; this makes it more comfortable for the welder to work
I designed it as a support, similar to those used for tower vessels; the wall thickness of the left cylinder is 8, while the thickness of components 1 and 3 is 24, and the thickness of component 2 is 16. The support is secured using bolts that pass through concrete beams (with pipes having a diameter of 38 running inside these beams), and it is installed on top of the concrete beams. I have a few detailed questions: 1. For the weld in the upper left corner, the steel chimney catalog specifies a 35-degree chamfer; how should I determine the appropriate value for mine? 2. What should be the diameter of the holes in the steel plates marked with blue circles? (The bolts are M24, and the diameter of the distribution circle is 4.7 meters.) I’m concerned that construction errors might be too large; holes of such a small size may not allow for proper installation.
It’s not a big problem; it’s done by hand welding, which results in some waste of welding rod.
For groove welding, how exactly is the angle determined?
Groove welding is one thing; bevel welding is even more difficult to perform.
Cylinder 8, bottom plate 24 – the fillet welds are really annoying
You’re a chimney! ! There’s no need to deliberately enlarge the bolt holes; even if such long foot bolts are misaligned, they can still be adjusted back into place ； It’s fine to cut the groove according to the atlas; with shims in place, just be careful about the gap ； Be careful with the heat input during welding to avoid penetration
This is not a chimney; it’s a flue for waste heat power generation, with a designed temperature of 400 degrees. The bolt holes are oblong in shape to accommodate the thermal expansion of the flue.
If the speed is high, I think MIG welding will suffice; just use a longer welding torch and that’s it
