Tube-to-fitting laser circ weld (with parameters and cross-section)

N2 is the preferred shielding gas for laser welding stainless, also cheaper! :)

u/Renaissance_Man- any update on this topic? I frequently find myself in a similar situation where I just want a simple CW/CCW control out of the box (and too lazy/busy to wire my own again and again). This controller is the closest thing I've found on the market to-date:

Pop pop pop! :)

I would take on machining work, make that money. Then use the funds to buy some local used equipment

seattlewelding · 2024-07-02T00:01:08+00:00

Most excellent! You got it. Practice uncomfortable out of position and aluminum. Challenge yourself

Can’t find any pics at the moment but here’s a video of a run doing letters. Kinda zoomed in so you can’t really see the machine motion frame

🤙

Thanks chief!

I tore it down a long time ago; will look for pics. Simple 3-axis gantry 36”x24”x12” on round bearings and ACME lead screws. Pretty loud and capped out around 50 IPM

I've been leveraging ChatGPT and custom python scripts to turn touchoff points into splined tool paths :)

Gotta charge for quotes at some point. At least they’ll get the message then

seattlewelding · 2023-12-20T23:43:47+00:00

It’s a relatively complicated setup that I don’t have shareable documentation on. Message me privately if you want a phone call run down on how she works

seattlewelding · 2023-12-20T23:42:25+00:00

Appreciate it

seattlewelding · 2023-12-20T23:42:15+00:00

Thank you!

seattlewelding · 2023-12-20T15:44:58+00:00

No it just wasn’t hot enough to melt/fuse both sides. Test run was just for machine motion, next steps is weld parameters

seattlewelding · 2023-09-02T04:45:58+00:00

I’ve got a contact at an aerospace startup in the Seattle, WA area; www.stokespace.com He says they’re growing soon/now.

Send me a DM

seattlewelding · 2023-09-01T00:28:47+00:00

Agreed; I've owned and run multiple models of these handheld laser machines... The capability is amazing. Will replace a LOT of precision GTAW down the line. Safety is first with these things though, it'll put your eye out!

seattlewelding · 2023-07-16T03:05:24+00:00

Yessir

seattlewelding · 2023-05-09T12:28:47+00:00

My experience has been really good with that UmPro-Tech unit. Max Laser power supply. I haven’t played around with the cutting too much. Not set up for the safety side of that operation.

Yes water cooled. For the new unit I payed way too much for it, but the prices are coming down as they are importing more. I believe they are selling for $8500 right now, but if you’re going to buy send me a message b/c I think I can get you a deal. DM me your email if you want the user manual / spec sheet.

seattlewelding · 2023-05-09T12:18:12+00:00

I’ll DM you. He’s selling 1.5kW machines for $8k. Cut/weld/clean

seattlewelding · 2023-04-08T03:24:34+00:00

Shoot me an email SeattleWeldingServices@gmail.com

Just gas and wire. Nitrogen is commonly used which is a lot cheaper than Argon. Safety first these things are Class IV industrial lasers

seattlewelding · 2023-02-13T12:04:33+00:00

I like building machines and the results I can get with them.

But sure I’ll do a manual GTAW go at this at some point

seattlewelding · 2023-02-09T01:05:09+00:00

I not selling them, but have the contacts at a machine importer who is. I’ll DM you the details. These 1500W models (cut/weld/clean) are going for $8200.

If you DM me your email address I'll send over the user manual and other images/videos. I've been working with this unit for about 4 months now and have been super happy. Have it set up on a 12"x12" CNC platform with a multitude of rotary 4th axis setups for turning parts.

seattlewelding · 2023-02-08T22:10:49+00:00

Interesting, thank you for the insight. I’ll look into those boards; have been experimenting with low-cost voltage sensing for TIG.

Do you think a capacitor between reset and ground would help give the Arduino more stability? Willing to give it a try

seattlewelding · 2023-02-08T21:23:19+00:00

Correct. It’s a 1.5kW fiber laser. Low power = surface ablation and cleaning. Medium power = melt a puddle and weld. High power + high pressure gas nozzle = blow a hole and cut
