Re: [MW:33919] Request for Information

Use of string / Weave weld bead according to ASME Sec.IX is considered non essential variable which is considered as the requirement of ASME B31.1.

See below snap shot.

But Client Specification will have control over the Bead width. For eg see snapshot

Some consumable Manufacturer's Welding Handbook's also provides some guidance.

Normally Weaving will have an effect on the below.

1. Weld pool control depending on the Fluidity of weld liquid metal.

2. For low temperature metals will have an effect on the Charpy Impact properties as Weave width increases the Travel speed will be low and hence the Heat Input will be higher which reduces the cooling rate and hence aids in coarsening of grains and hence the charpy Impact properties.

3. Will have a problem in positional welding.

Dear Experts,

It's a very nice platform to gain & share knowledge.

I have a query regarding the weld bead length. What is the maximum weld bead/weave length in Power Piping? (ASME B 31.1)

or 

Is there any thumb rule for weld bead length?

Your idea/advice will be highly welcomed & appreciated.

Be safe & have a healthy Life

Thanks,

Kind Regards,

G.Gughan
