I require sales quotes on Industrial Stand-Up type spot welders. I would appreciate any leads for distributors and/or rebuilders of such equipment; sales leads located in my area would be a bonus. Thank for your time !

I concur with CWIC that you must carefully review the current process. Eliminate current manufacturing issues and identify your quality requirements. Bad welders don’t justify automation…....get them help! ;)
If your still considering some type of automation, then your application needs to be...
Good question..i did some quick research and found this:
718 welded in the aged condition > The excessive softening of the HAZ due to solutioning can result in cracking in the areas adjacent to the weld metal. This is because, owing to the softening of the HAZ, these areas become the weakest...
Just to clarify the WF speeds above were used in the 1G position. For an UH fill I would probably start 200-250 wfs 26-28 volts.

Diffusion rates of carbon and chromium are much higher in b.c.c (ferrite) than f.c.c. (austenite) lattice.
In ferritic SS rapid cooling from above 925C does not really supress the precipitation of chromium carbide at the grain boundaries. For the same reason, lowering the carbon content does...
I would recommend employing FCAW for all Fill/Cap Carbon Pipe Welding, 045 wire with a C25 gas mix, which will produce minimal fumes. Our weld quality was extreme and very cost effective(4"Dia-200 / 8"up-330wfs). FCAW can lay a good bead even on 20" Dia and up. On big dia. your...
You are using the recommended filler 320LR.
Start and stops are critical on this material, craters must properly filled; and make sure yor getting enough gas Pre and Post-flow.
Do you see any benefit from using pusle ? why not straight DCEN tig ? Weld heat input must be keep to miniumum, to...

I was hoping to get a few helpful leads on proper job estimating techniques used in industrial pipework contracting; job costing for pipefitting, welding, and installation.
I have been in the piping industry for some time as a welder and pipefitter, and i understand that...
What type of robot is it ? (MotoMan, ABB, Fanuc, etc..)
I had a similar problem like this once. A control parameter might be switched, so your actually typing in AMPS required and not WFS ?...EVEN IF YOUR SREEN SAYS WFS INPUT
Your PS is CONSTANT VOLTAGE = Current adjusts to maintain a...
I am trying to locate TTT curves for various materials specs. Would anyone know where i can find these "Online" and/or a recommend a good atlas for purchase ? Thanks

Why do you want to measure the HAZ ? Are you concerned about HAZ's are overlapping ? Shouldn't you be more concern about producing an acceptable spot weld of required strength. How about a detructive test ? There are a few different types of destructive tests you can perform.

WELDER 123 > Are you referring to PE Pipe Fusion employing a heating element. If so i have some literature on the subject.
Polyethylene (PE) platic pipe fusion for gas pipeline employs a heating element...and its is not a manual welding process. The pipe ends are heated, the heating element...
This is to all of us posting helpful hints and information.
Not that im looking any type of gratification ! But when you actually go out of your way, on your own time, in replying to a thread ...a simple Thank You ! or hey thanks for your input ill keep you posted on my progress !..it's kind...
I agree with EVELROD.
You should be employing the FCAW process. Although SMAW is perfectly acceptable as well, you need a high deposition process that will cut through the mill scale.
FCAW - E70T-1 is an all position wire, designed to give give you superior mechanical properties with X-ray...
You might also want try an Argon / Hydrogen shielding mix for your GTAW process.
Argon/Hydrogen mixtures are often used when welding metals such as Inconel and Monel. It can also be used on STainless steels. It is used when no other hsielding gas can prevent porosity. Note it increases the...
I pretty sure your problems lies in your tack welds. I assume your tacking with GTAW. Good..Now the parts are SS, which means argon gas shielding is critical, as shielding and backing gas. However, your parts are so tight together i wouldn't think youd be able to use backing. The reason is on SS...
