test piece bender

admin

in class we have been welding up test peices and using a special bending machine to make the root and face bends to see if they fail.  the machine we use is specially made for this purpose, but was wondering if anyone has built or has used something else to bend these pieces...  id like to further my testing abilities and be able to weld and test myself at home.

Reply:at my school, they have a set-uop, that uses a car jack and a thing made from steel that looks like a 3/4 square. You put your welds pn the jack and jack it up untill the metal bends or breaks, then the teacher looks over your weld. I hope this helps.

Reply:I think there is plans for a test jig In the Lincoln handbook of arc welding.  If you have a hydraulic shop press and build the jig you can bend your own coupons."The reason we are here is that we are not all there"SA 200Idealarc TM 300 300MM 200MM 25130a SpoolgunPrecision Tig 375Invertec V350 ProSC-32 CS 12 Wire FeederOxweld/Purox O/AArcAirHypertherm Powermax 85LN25
