Lip weld?

admin

Hello!I'm an interpreter from Russia. I usually work with technical texts, and very often in the area of welding.Here is a question:I have a flange and on its rim there is a little ridge on both the parts of the flange. This ridge is   intended to melt for making a weld to seal the flange.What do I call this weld?Lip weld?Another case:I have a tube and another tube of smaller diameter in it. They are so placed that their ends coincide to make a weld on them. What do I call this weld?Again, lip weld?Third case:There is bellows and I have to weld it to a stem and body of a valve.Will it be correct to name these welds "lip welds"?Thank youLast edited by Jack8rkin; 10-13-2011 at 07:04 AM.
Reply:Hey Jack,Your first description(flange) is simply an "autogenous seam weld" since you are not using any filler. Your telescoping tube description would be a "seam" weld with filler or same as previous if no filler. Your last description would simply be a "butt" weld. You could always go to the AWS forum to get more elaborate specifications if you need an "exact" description.DennyComplete Welding/Machine/Fab.

Reply:Thanks a ton!What is a lip weld then?Could you please elaborate on that?
Reply:lap weld, perhaps.
Reply:Nope, it's a "lip weld"E.g.:1. An assembly comprising two plane flanges, said flanges having bores formed therein to permit joining of said flanges by studs received in said bores, the assembly including: sealing means having an inner lip weld formed in the plane of the joint of the flanges, being disposed inside of the inner periphery of the flanges and centering rings disposed around the studs in their respective bores. Taken from here:http://www.patents.com/us-4184785.htmlThe matter is that guys working for our company use one single term to denote the welds I described in the first post.In Russian they all are called "usikoviy shov" (to grasp the idea, it's something like "feeler/flagellum/string weld" in translation).It is done by melting a ridge going along the edge of circular parts to be joint together sometimes with adding some welding wire, sometimes without it. The first purpose of this weld is to seal the internal cavity of the workpiece. There may be a second purpose, and it's to be a load-carying weld, but it's rarely used as I have been told.Well, I'm looking for a good analogy to have proper translation for this kind of weld.As I was told, it is basically an edge weld. But the term our guys use is diferent from that one, because in Russian an edge weld is "tortsevoy shov".Sorry for a ton of letters...Last edited by Jack8rkin; 10-13-2011 at 01:55 PM.

Reply:I got a pic on the internet of the weld I'm trying to name properly.There is also a machine shown to cut this weld off.This kind of welds are sometimes cut off because they join replaceble equipment to permanent body (or smth like that), and as I said are usually used to seal the internal cavities.

Reply:Edge Joint Def.  " A joint between the edges of two or more parallel or mainly parallel members".I'd go with edge weld, here's a link.Last edited by Baila La Pinza; 10-14-2011 at 08:14 AM.
Reply:I think you can call it a lip weld as that is a feature of the parts involved. The designation or print callout of the weld by itself would be" butt weld" if there is no joint preparation or "V groove" if the edges are prepared like above.Our designations for welds  only concern the joint itself and have nothing to do with part feature. IE The weld symbol points to the lip area and the callout shows the weld type with a symbol and parameters.Matt
Reply:Thanks a lot.

Reply:There are all kinds of joints but really there are only two types of welds... A groove weld or a fillet weld.  From what I can imagine these welds are groove welds with a limited penetration depth.  Why complicate things with terminology??... other than to mystify and befuddle.
Reply:Yeah, I understand there are only two types of welds and lots of joints.Still, in Russian, guys call it a weld (or a seam if I may say so), rather than a joint. Established terminology, I guess.Well, you know, when a Russian welder tells somebody "Oosovy shov" in Russian, during a meeting with a foreign delegation, I have to say something in English so that the other side could visualize the weld I'm describing... In Russian there is a well established term, whereas in English there is no a direct equivalent for that as I have just discovered.So, I'll have to use an approximation in the above case, something like "edge weld" or a "lip weld". A good thing will be if there is a sketch or a drawing. Two welders can easily come to an agreement if they see an image of a weld. What if there is no image? Descriptions, descriptions... words, words, tons of them...Last edited by Jack8rkin; 10-14-2011 at 09:33 AM.
