Third sentence reads "Non-pressure retaining fillet welds, as defined in other sections of the Code, may as an alternative be qualified with fillet welds only. Where do I find the definition of non-pressure retaining fillet welds? I have searched this site without results and our AI is also...
Do these two coatings offer similar corrosion resistance? The application is fasteners (screws) used on medical exam tables and therefore protection is required to prevent corrosion from exposure to cleaning/disinfecting solutions. Also, since testing per ASTM B117 does not seem appropriate to...
We heat treat 17-4 bar to the H1100 condition. There have been times when the chart recorder is not turned on. When this happens, I have them rerun the parts for the full four hours. I ran the mechanicals for one four hour cycle and compared them to parts ran for two four hour cycles...
One of our material suppliers recently sent us 303 stainless steel instead of the specified 304. The material was machined and then welded. The welder noticed the appearance of the weld was much different. The supplier was contacted and they admitted their mistake.
We ran a chemistry on the...
We are trying to reverse engineer a flexible light arm with a light attached to it.
The arm is made in three sections. Each section is made from three strands of coiled wire separated by a triangular shaped wire. The smallest section is made from .101” diameter wire, the next .126” diameter...
I am looking for a company that can provide service on a six year old Metorex ArcMet 930SP optical emmision spectrometer. The burns produced by the unit seem weak (for the lack of a better disciption) and the resulting assay analysis is inconsistant and does not match the metal being analyzed...
Thanks for the suggestions.
The crack is longitudinal at the centerline of the weld and I agree it is a hot tear.
The weld seam is held very tightly together in the Jetline seam welder. The copper hold down fingers are designed to push the material down on the water cooled back up bar as well...
SA-240, Type 201 14 gauge stainless steel blanks are rolled and welded (autogenous) on a Jetline seam welder. This becomes the shell to which heads (SA-240, Type 304) are autogenously welded to make autoclaves.
One shell is 9" in diameter with a 12" long weld seam. Another shell is 11" in...
A heating element is incorported into the wall of a small (3" diameter by 2" high) die cast aluminum (A360) boiler used to generate steam (from distilled water) for sterilization. After a few cycles, white debris is found throughout the system. EDS analysis confirms that it is mostly aluminum...
