To JTMcC,
It's funny you mention Super Glue, it's the running joke of the shop,i.e. " you want me to glue it on?"
Seriously tho,we are using 5/32 6010 and producing a sound weld that passes independent inspection. It's just too slow, and I need to speed things up. We are 360 pcs. into an order...
Metengr,
Thanks again for your input concerning this ongoing problem.
It would appear removing the zinc coating will not be a option due to cost concerns.
Currently, we are using 6010, production is 40% lower.
I was not aware that there was a wire called Galvacore available,and I try to keep up...
This is a follow-up on my problem on welding galvanized A588 steel,and DEANC has peeked my interest for a solution.
Is there a effeciant way to remove the zinc coating from the thread area of the nuts to make them useable if we were to attach them prior to hot dipping?
My research on this has...
Thanks everyone for the input.
A special thanks to METENGR for the accurate info. once again. I do agree strongly that this design is NOT the best way to go.
Unfortunatly my concerns,this being one of them, were ignored by managment.
To METENGR, the coating,which was supposed to be .020 to .030...
We are welding hot dip gal. 7/8 - 9 nuts,A325,to hot dip gal. 7x4x1/2 A588 angle and are having a problem with cracks in the welds.
The process we are using is FCAW,gas is Co2,wire class is E80T1(8100 dual shield).Volts are 30,amps are 280 resulting in over 50k joules as required by NY state...
Once again I totally agree with sayeeprasadr with the suggestion that a "decent" attempt be made to use FCAW-GS.If getting a "stright story" is a concern, getting a CWI on site would prob. be the answer so an independant opinion is presented.
I would also have to agree with...
The response to your question on stud welding integrity from Sayeeprasadr is absolutly correct.The "spill over" is what we call the collar.It has no structural value to the weld.We use a ceramic ferrule for the stated reasons,as we use studs at least 19mm dia. The welded area of the...
One way to distinguish between hydrogen embrittlement from other sources of failure is to determine where the weld failed.
If it lost integrity anywhere other than at the toe of the weld,such as in the effective throat,this MAY be a clue.
I stress the word may, because metal incompatability...
The only portable welding "machines" I am aware of require a source of constant power, i.e. generator. If a welder operates on stored power,battery,the arc will become increasingly unstable as the stored power is diminished.
By "4-5 electrodes", I assume you mean SMAW...
Welding 24 ga. 1018 can be problematic. Our answer was to forgo speed of welding this type of material(Mig)for inspection/vs. quality welds.That would be Tig welding with small diameter electrodes,filler metal if required.
A good Tig welder should be able to make up the produtivity that would be...
I would like to get some input on the right drive wheels for use on Flux-Core, .045 8100w wire. Our supplier wants to sell us 8 new "state of the art" guns. Oxo brand. The premise is that the new design will reduce maintainace costs, i.e. contact tips,nozzels,diffusers etc.
We have...
