good rough-and-ready measure of fillet size

Nov 17, 2014 3 Replies

Hello all



I'm doing some work - Factory Production Control systems for steel fabricators.



If the welders can readily measure their fillet size, they can



- "calibrate" their judgement and keep just over (-0%/+small%) the required fillet size



- it isn't necessary to design conservatism into the fillet size specified (???)



Fancy gauges like "The Welding Institute gauge"

produce farcical inconsistent results - thanks for demo by good friend, where a room full of welders and engineers got wildly different measurements many of them clearly nonsense far from the obvious "about 6mm" (or whatever it was).



There is the "Murex fillet gauge"

This looks good - simple, robust, rough-and-ready, little-affected by shape distortion around the weld, etc, etc, etc, etc. And cheap - so every welder can have one.



What do you reckon? What do you use? What do you specify? etc.

Essentially - there is no fudging the issue that if anything you've put your name to goes hideously wrong and you've been negligent, you will go to jail. That's the "Responsible" bit...! So no matter what worldly pressures would have been applied to you, you will not sign-off that a load of ****. The vision of the prison cell prevails. So the effect of the legislation is that it is not worth discussing with your Welding Coordinator his chances of promotion if his attitude to his work does no improve (sic.), not sketching out the uncertainty of his job tenure is she/he is not "realistic" (sic.) about the issues, etc.

Apparently "Responsible Welding Coordinators" have gone to prison when they have signed off on documents passed through their car window in the street outside the factory and pocketed the tidy sum of cash.

Is that a helpful answer? I hope it sketches out the real dynamics...

Regards and best wishes

As a professional welding inspector, I use the simple fillet gauges. They are very hard to break.
