If your talking reinforcement in the context of a fillet weld then it plays a huge part. Do you have the template gauges for measuring fillet welds? https://weldingsupply.com/cgi-bin/einstein.pl?PNUM::1:UNDEF:X:MG-11 I am talking specifically of Groove Welds. Some clients ask specifically to remove...

Mind explaining a bit more? Like you are doing groove welding(V groove) and you have joined the test coupons. After the final pass you get the reinforcement on weld about 2-3 mm. So the question is ,Is it necessary to remove the reinforcement. Does the reinforcement has any role to play in the join...

What kind of role does reinforcement play in weld?
Is it allowed to grind the reinforcement of weld.

Thank you all for the answers..

Which is the most difficult material to weld and why ?

Is it possible to join residual filler wire of Inconel 825 used in TIG welding. After joining the filler wire using the TIG torch, will it affect the weldability, properties of the weld material.
Thinking of putting that as a continual Improvement but concerned .

Hello!
Welcome to the forum.

Thank You Mr.Otto.

@ Shastri11 - start by reviewing this tech sheet on Martensitic 410 Stainless . Your purported through-hardness value of 170 BHN is below the avg for 410SS, most likely owing to your reduced (from 0.15%) Carbon content of 0.12%. Typical avg values achieved for hardened/tempered 410SS are 200 BHN (3...

I have to test SS410 bar which has undergone " Hardened and tempered(T)" heat treatment for impact testing. Bar dimensions - dia. 100mm, length - 600 mm. Chemical composition : Carbon 0.12 Silicon 0.45 Manganese 0.85 Chromium 12.01 Phosphorous 0.008 Sulphur 0.0056 hardness 170 BHN The bar ...

Does anybody have an idea as to what mechanical property the material will achieve knowing the chemical composition and the knowing desired heat treatment to be selected ?

What kind of electrode i shall use for welding SS304 to SS310?
I used E310 to join 310 with 304 but it induces crack instantly.
Please guide me through.
The thickness of the plate is around 6mm.

I mean to say the purpose of all weld test sample . That does not help. You are not describing a test we are familiar with, with language we know. Describe the test. Is it on pipe? Is it on plate? What process are you going to use? What position is it in? Steve S I mean to say the tensile test samp...

I mean to say the purpose of all weld test sample .

Can anybody tell what is the sole purpose of all weld test sample?

I have experienced lot of spatters coming while welding the material. Also the weld metal is not deposited uniformly.

Yes the polarity we used is DCEP.

While we were welding WCB material we hardly got chattering sound while welding. But this one batch of 7018 rods we procured is producing this chattering sound plus there are lots of spatters. The electrical characteristics we used are same as the previous one.

Do PMI(positive material identification) if you want to know which grade it is. Else using 309,309l would be a good option.

When I go for welding nodular Austenitic Ductile iron ,the problem I face is of graphitization.When I did the microstructure analysis I find graphite flakes rather than graphite nodules.The chemistry of the job is maintained as per standard. Please guide me through. So instead of repairing we have t...
