Edge Preparation and Fillet Welding

Mr. sb is correct these are very basic questions that any welder could help you with. Most of the times on fillet welding the only edge prep would be to clean to remove and contaminants by brushing or grinding the surface before welding. Usually butt welding does have edge prep in the form of beveling and many times more such as counter boring to match ID of the two pieces. I personally would not strike an arc on a butt weld of any significance without at least some edge prep but it can be done. Preparing the edges of the pieces to weld in a weldment by grinding the metals to be free of contaminants is the first step to making a good weld IMO.

I agree with sb.

If your company does the manufacturing I suggest that you talk to the welders.

In the various companies I have worked at, I found it very helpful to be friends with and help anybody in the shop.

If I helped them when they made a mistake without belittling them, they would help out when I made a mistake.

Hi...

Please let this forum not become a class room. It should be use for consultancy purposes for obtaining genuine solutions.

you folks seem insulted at the idea that someone would ask an elementary question.

dinakarj, I agree it's best to do the research in a reliable source. You should be familiar with weldment design before using them in design. Needless to say, weld failure is a very serious matter.

I would recommend Lincoln Arc Welding Foundation http://www.jflf.org/ They offer some great affordable materials and some free info too. And it's based on practical application of their years of experience. if you want a metallurgical thesis on weld mechanics you should go to the journals or a graduate level study. Hopefully this helps a little more. If there is someone at your facility who can be considered a master welder or senior engineer, I would ask them as well to help you after you brush up on some basics.

Best of luck

Hi...

You need not take it otherwise. This forum is for advise and please let it be so. It appears the gentleman has been given a lot of responsibility for which he has little or no training. There is another question from him in this forum. It is a pure commercial matters question on import duties which should logically be addressed to a Custom House Agent.

We must not discourage inquisitiveness but must nevertheless discourage mediocrity.

Hi Dinakarj,

I would recommend you to buy a copy of welding technology and design by V M Radhakrishnan printed in India, it will answer most of your basic welding queries.

I did a British apprenticeship and one of the first things that we were taught was "if you don't know ask!"

If you're in doubt also ask!

I have been working in India for over two years and most Indians don't ask, this is more of a problem than asking simple questions!

Keep on learning and remember "knowledge is potential power" or as I prefer potential cash!

He woldn't learn.

Despite all these again he asks another fundamental question.

decided to neglect him.
