Help with price please

[Stateline Welder]

I need help pricing this type of work. Potentially 200-300 plates like this per week. All of the material is provided, welding studs and plate. The plates will have to be cut and the studs welded to it. Mig

I'd figure out an hourly rate and then try to average how many you can do in a hour if your customer wants a firmer price. If you had a shop rate maybe deduct 30-40% off for the materials being supplied. If you had a shop rate around $120/hr. maybe charge around $75 to $80/hr. Nice welds by the way. Looks like they are for reinforcing/holding concrete together. Better than the questionable welds on the bridge that collapsed.

Add in some quality control / testing. And fixture fabrication. Once you are rolling it will go fast. So price it per plate then work as fast or slow as needed.

Any prep on those studs?

Hard wire Mig would not be my choice for this job. Do some testing. That might influence pricing.

The welds look to be run fairly hot showing good fusion. The nice thing with using Mig is you can do a complete donut weld without having to worry about slag when you come to the end. One continuous weld is much faster too. I did thousands of donut welds with 7018 welding ladder rungs for oilfield tanks and the slag from the start could pose problems. If strength is a big concern, you could always drill holes in the plate and plug weld the back side. I think the studs would bend over before breaking looking at the welds shown. It looks like it could be a pretty monotonous job but a job is a job and there's much worse jobs.

r u sure mig? i think i still have a couple just like laying around my yard. a stud welder was used. if so, a welder couldnt compete w/ a stud welder

[Stateline Welder]

Yes definitely mig. Yes a stud welder would be much faster, although it isn’t in the budget just yet😀. With plates cut and pre-marked it takes 2 min to weld. Will different regions have an influence on prices? I’m in Alabama/Georgia if anyone thinks location will have a price per hour variance. Thanks for all the help👌🏻

You need to consider cleaning the weld points for MIG. Picture doesn’t seem to show any shiny metal. That could take as much time as welding.

If you do not intend to grind mill scale, I would want that in contract or you could be left holding a lot of fixtures.

Do you know what they are for? If they are just wall plates, mig weld them. If they are structural plates, I would dual shield mig them.

But that cant be more then $20 if your doing 250 of them. So $4 each weld and $4 for the shears.

I would make a top plate with 4 pieces of small pipe welded to it as locators.

Around here, Mexicans would do that with stick welding for $5 a plate.

I'd offer to do that for $20 each plate. Looks like easy money!

The welds look pretty good to me. Even using a stud welder you can have problems with the welds. Look at thread where the bridge collapsed. I'd do a test plate to see how strong the welds are. I'd bet you could pound the crap out of them and the weld would hold. Simple enough to test a few of them.
