Hello all, one question.Currently a weldor enlisted in the USN, and just recently stationed on my first ship after 3 years at a shore repair facility. Since I've gotten to the ship, gage lines are going to be the death of me, i get them about 3-4 times a week. they are all the same size, schedule. 1/4 schedule 80. and i consistently about 2-3 times screw them up after OP testing them. they leak on the top toe of the weld (the toe on the gage line). i file out the discrepency and repair my mistake but what in Gods name am i doing wrong. In my opinion i dont get it too hot, i run a straight, good looking bead all around whether the metal, cres to cres or Cuni to cres vice versa, I aint no dumba$$ i think i know my way around but i keep gettin pinhole leaks on my welds. any help will be greatfully apprceciated
Reply:Running hotter usually fixes any issues I have lol. Do you stack the beads in the fill or single passes? Since it's running on the toe line, could you extend the bead size a bit wider than you usually do and still be in tolerance/code? Are the leaks at your tie ins or restarts? Feather the restarts, maybe start the torch about where the leak is, get it hot, then back up about half inch and start your weld.Idk bro this seems above my pay scale.
Reply:badnews, I think you about covered 50% of everything I DIDNT think about, i thank you, lol. i'm pretty sure its feathering the restarts, because I didn't pay attention to where the the restarts were after i tried to repair, on top of all of that the fittings are old as dirt and clean as a whore so i think that oughtta help thanks brother
Reply:The fittings are dirty and you have porosity at the toe lines?Sounds like you are not cleaning far enough back from the weld.Did you clean an inch back from the weld inside and out?Dave J.Beware of false knowledge; it is more dangerous than ignorance. ~George Bernard Shaw~ Syncro 350Invertec v250-sThermal Arc 161 and 300MM210DialarcTried being normal once, didn't take....I think it was a Tuesday.
Reply:i get pinholes on the top toe, gage line side not by the fitting. granted the depth of the fitting i get is usually only 1/4-1/2" its a pain in the *** to clean out but i ain't the most patient kind...lol got me there thanks yall
Reply:A handy tool is a die grinder if you don't already use one. Or even possibly a dremel if you need something tiny. Use some small carbide bits and you can pretty much clean up any surface you can see. Almost.
Reply:yea i oughtta get my hands on a dremel..just too cheap to dish out the money lol thanks yall |
