Steve, I couldn't have done it without you guys. Yes I'm having a cold one but thanks to all you!

It's been a long and rough last couple months for me. I have a background of 14 years in the machine/welding shop for the AF. I never had a problem with the aircraft welding cert. Fast forward to the civilian world. I was never formally trained in mig welding. To be honest alot of what I learned I l...

The plates are packed up and will be getting shipped out tomorrow. Come to find out the company I work for noone is certified. I will be the "test bed" for getting everyone certified. The company I work for has over 1K employees too.

Steve thanks, I was worried the overhead didn't have enough cap on it. For some reason I started getting bad porosity come to find out I wasn't holding the arc short enough. They do have great penetration. I gapped them around 3/16 and burned it in real good. We will see.

I guess I'll be turning them in tomorrw. It will take about 4 to 5 days to get the results. I want to thank all yall for being patient with me and helping me out. Like I said I've never been formally trained on mig and yall help tremendously. Lets see if I put that good help to use. By the way I'm s...

Terrible picture sorry bout that

Let me see if I can load pictures, What do yall think? the left is verticle, the right is overhead.

Ready to run my plates today. I spent all day yesterday sanding cleaning etc. I took extra adderal this morning and am ready.

Ok I got my plates. I've got the machine set at pulse (which is cool with the tester) 50 and 300? I've started taking extra adderal too. The beads look great

they told me this would cover me to weld for the navy

I noticed the sheet of recommendations had something about "pulse" (it wasn't a WPS) I started reading the machine settings owners manual. After running a few beads really hot 30/440. I switched the machine over to pulse. It welds alot better now but I cut one of the coupons and I'm not ge...

My project manager told me it would minimlly quailify me to weld aluminum for the navy.

Alexa, No I don't know. Warpage is a PITA on this particular coupon. I literally had to clamp the test coupons down and put tacks all over. Then I was dealing with the gap closing. I'm gonna weld it up monday and I think I've got it. The knife edge was the trick, no landing at all! Now I'm wondering...

I think this will get me through it thanks

OK 1/8 material with a backig plate, tig welded with 4043 filler, miller sycrowave machine. What else?

I have to do a 22" aluminum butt joint in the horizontal position. Has anyone heard of this? What are they going to do as far as inspection? How much should I gap? SHould I bevel it?

now this sounds like what I've been wanting to know. I just found out I can go to the test faculity. I would much rather do that then keep mailing these coupons off.

I have a WPS but i had to fill it out myself. They then made corrections and sent it back to me. The difference was the the amperage and wire were bumped up. When I try welding to their specks the weld litterally falls off when welding in the overhead position. That tells me I'm not going fast enoug...

Damn I hate to sound ignorant what is WPS?

This helps, I was set up for faulure with the equipment I have. My next question is "what is spray arc"?

Let me try this again, I've got to do a welding cert for my work. It's 1/2 plate vert and overhead. I've done the plates once and they didn't pass the bend test. I welded them too cold. I've done welding certs with the air force a 1" tube on a 45 angle. I'm useing a miller matic350 p .035 wire,...

What wire do I need to use? I'm using er70s-6 now

I'm useing er 70 wire. So you think that may be one of my problems

base metal 4130

Oh ok there's a 1/8th backing plate .035 wire from a miller mig. both plates are 1/2 thick with a 45 angle. What else?
