[MW:3335] Re: Welder reapir %

Hi Adi,

If your calculating a repair rate by lenght you have to calcualte the repair rate by lenght for 2" and below also. since you are cuting and rewelding the joint due to practiccal difficulties in identifying repair location and reparing in small bore jointes i.e 2" & below sizes not because of repair length.

If the welder is requalified the repair perecentaage will start as fresh.

Thank Q to all

 

If I calculate full cut out (especially for 2") The repair % is coming too much

Exp: 10 joints 1 joints repair means 10%repair rate

However the repair portion is very small, I have to cut the joint

 

Observed welder repair rate above 5%, he should be taken off the job and sent for re-training for a week.. ok

After requalification his repair % calculation start from fresh or from the old ?

Hi,
Whatever amount of repair was caused by the welder and no. of joints repaired should be attributed fully to him. Indication type etc are immaterial, it is the bad workmanship that we are considering. And indication is repairable if it is a defect (not acceptable), right? Indicates bad workmanship. Accordingly it needs to be treated. But a record can be kept of % length repaired, just for comparison. Otherwise, it is for the % repair rate per joint that a welder's record should be maintained. Just for your info, If the repair rate shows sign of exceeding 1.5%, the welding supervisor should take cognizance. If it is >3%, the welder should be warned officially. Above 5%, he should be taken off the job and sent for re-training for a week. These are the general norms in the welding world in the industry. Or, so my notes say.

If it is cut and reweld, 100% repair to be considered for quality
costing; but, for welder performance, the actual repair/defect % only
to be considered - this is just a thought....
