Small project from work

Dan, a question

Have youy ever used the roller type rod feeder for TIG? I have seen them in catalogs and wondered if they worked, but nevere remembered to ask until you said that on 1/8" SS you fed the filler quicker.

What type,and size tig rod were you using?Also what mig machine did you use,the MM185 or MM250?

Scott thanks for answereing my question about the picture. I wonder what happen, because these same picture a very clear and the detail is very sharp when I view them straight from my hard drive.

Let me tell you first that 99% of the stainless steel that I weld on is 304L. So, for this I always use 308L filler rod. most of the material on this project was either .120 wall square tube or 1/8" thick. However, to help fight distortion problems the the angle iron peice has a 3/16" leg thickness. Know for 1/8" thick material most charts recommend a 3/32 filler rod. However, most of the time on a 1/8" SS I use a 1/16" filler rod and just add the filler rod at a very quick rate. With time I ve learned that this gives me better control over the stainless weld puddle. I tried using the 3/32 as suggested but since stainless holds so much heat and the 3/32 rod requires more heat to melt properly sometimes I would loose the fine control of the weld puddle that I like to have. Now, some joint designs require me to use the 3/32 filler. On this project, I had to use the 3/32 filler rod on 2 joints. The 3/32 filler rod was used to weld the 2 joints that run parrallel to the angle iron on the short peice of 1 1/2 sq tube that I notch to fit the the angle iron.

The MM 185 is set up as our stainless steel machine. I run a .030 308L-Si wire on it. The added silicon in the wire really makes a difference in how well the weld puddle wets out.

The MM 250 is set up as our mild steel machine I mainly use it for spray transfer. The other guys generally do all the thinner . 120 square tube jobs that can be done with short circuit transfer. The fun thing is I am amazed at how many times I catch them using my bottle of 98/2 and the nozzle on the gun that recesses the contact tip an 1/8" to short circuit transfer a project that they are working on. I tolds them multiple time to pay attention to this. Finally, every time I get a new bottle of 98/2 I take a black felt marker a write is large letters on the side of the bottle 98/2 spray transfer only! Well, this worked the last time someone used the machine after me the only problem is they for got to switch the nozzle on the end of the gun. You should have see the amount of spatter build up that the nozzle had on it.

Thank you Dan

Obviously I need to look at more pictures.... Really appreciate the extra information regarding what materials and processes are being used in posted pictures.

DAN................BLURRY..............I WEAR TRIFOGLES ONLY 2 OF MY LENSES ARE BLURRY.....................MIDDLE ONE IS ......ROCK[email protected]

Can someone tell me if the pictures of this film holder are blurry looking on there monitor screen. Reason I ask is because when I view the pictures from my hard drive they are nice and clear. However, when I view the picture that I posted on this site they are blurry on my monitor.

Very nice work like Russel said, it is a good learning tool for amateurs like myself to see good welds. You did not specify what process you used though. You mentioned TIG for the pipefitting, but it looks like you may have used stick for the bag film holder pictured though. My TIG welds should look so good.

Most of the welds on the film holder are TIG. The 2 welds that attach the 1/4" X 2" flat bar to the 2" sq tube in the close up of the pivot point are MIG welds. I work in a food processing plant,and the QA department does allow us to use stick, because of the potential product contaminent that any missed slag could create. By the way, the project is made out of stainless steel.

Yeah Dan, that was me ,THANKS for the photos and remembering.
I knew you could make excellent welds,and I was curious what you made that required that level of precision.
Like your design on that rack...like the way you closed the ends of the tubes,rounded the corners on the flats,beautiful job of fitting up...and with those nylon washers should be smooth moving and stable.Verrrry nice work.
I really enjoy seeing how weldors who weld for a living do it...only welding I get to see is mine..except on here..



thanks again,
russell

Dan,

Beautiful welds! Nice to see them in projects! Keep the pics coming.

Those are some nice looking welds!!(as he bows down to the welding god) ...what was the setup they were done with??
