Re: [MW:10477] Weaving

Hi

 

Max.weaving of 3 time dia of electrode is thumb rule,

 

But, if you proved more than the above during the PQR by taking the macro cross section , it can be allowed.

 

Thanks & Regards,

Dear Friends,

 

WPS says the weaving is allowed/permitted 3times the diameter of the electrode.Please tell me wheather we can allow if the weaving is more than the allowable limit.If it can be allowed.What is the reasons and on what basis it is allowed?If it can not/should not be allowed.Why and what is the reasons?

 

My opinion is that it should not be allowed.[1]Because it deviates from the WPS.[2]properties may vary because of the excess heat In put due to excess weaving.

 

The contractor is of opinion that they will change the WPS to suit excess weaving.It is not an essential variable,hence it can be allowed.To substantiate their claim they say they will change the WPS and they will perform Hardness Test to prove that the properties were not changed.

With Best Regards

Sampath
