Welding estimates

Welding estimates

(OP)
I'm trying to estimate welding manhours for a design and I was wondering if there are any resources on the web that would help me.  A rule of thumb would do, but also I want to know which welding processes take longer than others.

RE: Welding estimates

It depends what kind of work you are trying to estimate. There are pretty good tables available for most welding processes. In precision sheet metal work (oxymoron?) you generally find that the handling, assembly and location of parts, jigging etc. take a significant amount fo the total time.

What type of welding work are you trying to estimate, what are the ranges of material you use?

RE: Welding estimates

(OP)
I'm designing a carbon steel vessel to contain gas at a low pressure. The plan now is to fillet weld a flat, oversized top onto a 24" tube.  Material thickness will be between 1/8" and 1/4".  It doesn't really matter to me what type of welding is used so long as it is airtight.

RE: Welding estimates

For welding costs estimation I use a cheap and nice software called COSTCOMP. You can find information at www.nil.nl

White Paper: Agile Product Engineering and Improved Product Outcomes
Today’s product development cycle is fraught with difficulties. Increased demands for complex functionality and reduced product development windows cause engineering teams to borrow practices from the IT industry, swapping outdated serial workflows for a more flexible and collaborative design method known as Agile Product Engineering.
