Re: [MW:30780] Run-Out Length for SMAW Process

Ref 409.1. increase in heat input OR an increase in volume of weld metal deposited per unit length of weld over that qualified.

Sir how we can find heat input in manual method. It's formulae

Dindo, this is not formula for runout length, it is alternative method to find out Heat input. Generally, for Manual welding process, to find out Heat input, it is always better to use run out length method.

From which refrence this formulae has been taken??

Run out length is the S in below formula, it is the length of the weld (mm or inches) with the corresponding time to do that length of weld (seconds or minutes)

Volume of weld metal deposited per burnt length of each Electrode. ISO 1101-1,2 maybe referred also

I am not sure with the below mails but I can give explanation to Run-out Length.

In SMAW process, the distance welded by a single electrode (350/450mm length) and it is related to welding speed

Thanks & Regards

PL. EXPLAIN MORE 

What is this ?

> 100 mm is min 150 mm
< 100 mm is min 100 mm

Or you can apply simple logic:

Thickness of base metal / each layer height = No of layers * 10-20  mm (staggering length at each layer depending upon the process)

Dear sir,

Recommended run in run out length for base metal thickness;
> 100 mm is min 150 mm
< 100 mm is min 100 mm

Dear Expert,

A week ago, i received comment regarding welding for smaw process.

My client ask to me, run-out length for smaw process.

I don't know what is run-out length.

Please advise me 

Thank you & Regards
