Glass work looks great Scott! I don't remember, do you have a gas bottle for that welder? He will need it with .030 solid core wire. I have been using .030 for 1/8 or thicker steel. When I move to the tub will use .025.
Yes, he has 75/25 mix. His Instructor has been teaching them to use gas with flux core wire, which is contrary to what I learned, but I'm staying out of it.
IIRC he has a huge Argon/co2 bottle.
On the perosity, all the oil was removed from the tube? And the Argon isn't used with flux core. I know you knew that, or Clay did.
You do some great glass work buddy!
Yes, oil was removed and the weld areas were cleaned and ground first.
And you should see the crater welds produced when you, ummmmm, forget to turn the gas on with solid core. Not that I have ever done that.
I am guilty of that myself! Not intentionally... just when I ran out of gas I couldn't figure out why my welds were so crappy! It was on another project.
Nice glasswork,Scott....I just started dabbling in glasswork, so I can really admire yours.
After viewing your craftsmanship, Rich, you ain't gonna have any problems! Let me know if I can help. If you have a source for bulk resin that would be the way to go. 10CCs (I use a syringe for my catalyst) catalyst to 32 ounce of resin. This will give you about 15 minutes of work time, depending on how hot it is outside.
As far as the spool wire goes,AJ might be right, depending on what size wire Clay actually used.
.030 wire is real nice for the cage. .035 is alright,too.
Other common sizes are. 045, and. 062, which would be too thick for your project.
Maybe AJ said .062 and not .052. If Clay was in fact using that size it's because of his Instructor's teachings. I know when I got home from work today and sauntered out to the shop, I noticed the weld quality. It was totally uncharacteristic of Clay. It looked like he forgot to turn on the gas. He has been under a lot of stress with exams, and he has been going back to school on Saturdays to catch up on his welds, as he is behind. He's really wanting this semester to end!
Is Clay getting porosity just at the beginning of each bead, or throughout the entire weld? What is the cfh of the bottle gauge set at?With this information, we may be able to get to the bottom of this.
Clay gets porosity throughout the weld, and he has had the problem all along, even using .025 and .035 wire, flux core and solid core. He is running about 45 PSI. In my opinion, flux core creates a lot of spatter, with or without gas, and I think his Instructor is wrong.
There is also something called a leakdown test to make sure that you're not losing gas through a leak between the bottle and the tip of the gun. With the bottle opened, pull the trigger on the gun, and watch the ball,or needle of the gauge go up to where you have the cfh set to. When you release the trigger, the gas should stop coming out, and the ball,or the needle should drop to zero.
If it stays up a little bit, that indicates a leak in the system.
There's more to this porosity thing, but this is a good place to start.
I'll check that out tomorrow. I took it for granted that it is all tight since it is new, but since Clay bought it with his own money, I let him assemble it! Maybe I should covertly have a look?
