I am designing a simple mechanism, I have CAD drawings for the parts. And I am having samples manufactured. But I am running into a problem when it comes to welding specifications, the manufacturer gets frustated because I just tell them to where to weld, but I don't detail how to do it. This is very understandable since I don't want to tell them what it's for. But I don't know what to tell them, I want the cheapest welding available that will hold. That's the catch. But the force that the weld has to withstand is not great either, I feel that most things would do. I am thinking of buying the "Design for Welding" book from the AWS. But I am afraid of an information overload. Is there some simple guide for inventors so we don't have to become welding experts?
When I look at the welds done for the exercise machines at the gym it looks like that's what I need. They are not too rought but you can still see them. And I bet they are reasonable strong an cheap too. Maybe someone can tell me how strong are them, and how to spec them.
Anyway any help will be greatly appreciated.
