Re: [MW:10500] Weaving

Dear Herman,

We need one solution from your company.

We have to weld 3 mm dia SS 304 wire ring and there should be no burr  at the weld point.

The other conditions are as follows :

Material formation at weld point allowed : 0.15 mm

Demormation at weld point : 0.20 mm

Could you please advise us the best solution for this.  We need to weld appx. 100000 pcs. a day.

Thanks and looking forward to hear from you.

Warm Regards,

KUNAL KHATRI

Dear Mr. Barot,

For GTAW mostly maximum wide is specified as dimension , for example: weaving allowed max. 5mm

Dear experts,

same to be applicable for GTAW? means three times of filler wire dia? if not please give the reason.

Hi,

If the job is in low temperature service we have to strictly control it. In other cases it will not make serious issue. But as a good engineering practice, reduce the weaving to 3 times of electrode dia max.

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
