Help Stop Wasting of Student Welding Materials

[ContractHome]

We use a massive amount of material teaching our welders GTAW welding aon 1" NPS Carbon Steel Socket Welds and Also for Monel 400 NICU Socket Welds. We cut the pipe from the welds to reuse the pipe, but we are told that we must cut one inch away from the welds because the hardened metal from welding would damage the blades in our band DoALL Band Saw (Model C-916M).

Is there away we can treat the metal through some heat treat ment process so that the welded metal will not damage the band saw blades?

Is there an special band saw blades that would not wear- if the blades break or wear to fast it would not be time or cost efficent compared to the price we save on material or would it?



We would like to cut the welds right at the socket couplings so that we can reuse the sockets also.

I am looking for several sugestions to help save us money. Each Monel Socket costs over $100 a piece.

I am open to any suggestions for our welding students.

I'm surprised I am the first to question the assumption that the steel will be significantly hardened by welding at any appreciable distance from the weld. You should be able to cut as close to the weld toe as you can reach.

this.

You should be able to control the carbon steel socket and pipe. Make sure they both have a CE < 0.3 or so and you should be able to cut as close to the weld as the DoAll will get without hurting the blades.

Can anyone comment on weither this sockets may be reused for welding? Does the original welds change the material in such a way to effect the quality of the students welds or testing their projects?
