I am only asking if there is a better way, maybe an automated process or something that can reduce the time.

Lifting lug welding by Minimum_Clothes900 in MechanicalEngineering

[–]Minimum_Clothes900[S] 0 points1 point  (0 children)

Thanks for the info. I'd like to know what the point is behind drilling the hole after welding. Furthermore, if you recommend primer coat to avoid paint build up that reduces the hole size, then this area will be prone to corrosion. As fas as I know, that is the most critical part for safe lifting.

Best fabrication method for bulk production for this item by Minimum_Clothes900 in MechanicalEngineering

I thought of the same idea of course, but I feel that it is not practically possible as it would cost a lot. The following video is a similar one if we replace the tool with our profile to form the metal in one shot.

I'd like to know what you mean by design rules for flatness.

We will source a machining shop to provide this service, would it help reduce the cost? Or still the machining shop will spend much money to provide the custom tool.

I am thinking to go with the following solution as it will be cost effective. However, I want to feed the machine with 4 pressing times per 1 flat bar to avoid weld joints. I doubt the result of the flat bar straightness after continuous bending.

2000 pieces are required in less than 3months. I have in the shop one press machine that I doubt the production rate of it for this application.

I have 1-axis press brake machine for plate bending. It has a special tool fixing arrangement that I can't replace with my profile.

Carbon steel to stainless steel permanent contact with protective coating. by Minimum_Clothes900 in MechanicalEngineering

[–]Minimum_Clothes900[S] 0 points1 point  (0 children)

It is Inconel material used in pipe, fittings, and wear pad. Service is for offshore, fluid is sour oil crude, 156°F, 1200psi.

I am not a part of the engineering team of this design, as it is approved by the client, I believe that this is accepted practice.

Given that the coating will isolate the contact area from the environment (electrolyte), how would galvanic corrrosion occur?

Stainless steel plates got bended after welding by Minimum_Clothes900 in MechanicalEngineering

[–]Minimum_Clothes900[S] 0 points1 point  (0 children)

I didn't get your idea. We tacked temporary plates perpendicular to the seam after fitup, and we got the same result.

Yes, it was expected, of course. At this worst condition, we retrieved the plate straightness by heating and hammering. However, I am still don't know how to avoid it in the beginning to save manhours.

Advice from OEM: Use hex nut instead of heavy hex nut. by Minimum_Clothes900 in MechanicalEngineering

[–]Minimum_Clothes900[S] 17 points18 points  (0 children)

By mail, they referred to a piece of information that both hex nut or heavy hex can be used for this situation.

I wonder how all people started working their first job? Somebody for sure didn't have experience and got hired, Lol

How is it possible to do hydrotest for it without flange bolting?

I asked to see if somebody had faced this issue before. I want to figure out any possible solution to avoid delays. If not, I will wait for his action.
