I have a supplier that is proposing to change a large spot welded structure to laser welded. Structural issues aside, does anyone have any experience with volumetric inspection of laser welds (excluding x-ray)? Any suggestions on how to go about that? The sample provided to me shows a very...
I have a situation that requires a supplier to "check" if a large (60mm) nut has been "tightened". Ideally, I would like to confirm installation torque (400 N-m), or at least something very close to that. The nut has Loctite 243 applied and is in a very tight space. I am concerned that damage...
I have a large structure (60 ft by 10ft by 10ft) made of formed sections, plates, sheets and numerous welded joints (spot welds and arc welds). There are many large openings reinforced accordingly. It is designed to carry direct loads at variety of locations, in various directions. The design...
Hello All,
I have a deceptively simple question.
Suppose you have old drawing for a welding steel frame which includes flare bevel welds (single side). No weld size or prep. size specified.
The frame was fully analyzed via FEA assuming full connections (ie no special modeling for welds or...
In the A606 specification two conditions are noted for this steel, "as-rolled" and annealed; the mech. properties of annealed are about 10% less than as rolled. I am concerned that welding as-rolled material alters the properties to the annealed values in the HAZ. Does anyone know if...
Has anyone ever designed a stud connection (aluminum base metal. Stainless Stud) with a "jam" nut applied against the same base metal as the stud - i.e. drill and tap, apply the stud (with locite), then add a jam nut and torque to the value for stainless? This a box with 4 studs, one...
Where can I find a comparison or information on design loads for vehicles? Ideally, I'm looking for both carbody loads and bogie loads for US and non-US designs.
Thanks
