Tig Welding Cast Iron

In this video: Dana and Jeff get a small cast iron repair job in the shop, since we opted to Tig weld it we figured we would share it as a video here on youtube.
Darkmoon Metals is a home based business start up, I have decided to live my dream and work for myself. I am a trained welder with a strong interest in blacksmithing. Dana, a long time friend and talented artist has teamed up with me to create truly unique products taht will help us stand apart from other metal crafters. Join us for our ups and downs while we learn as we go. Trying to forge a new life in a dead economy that has left many blue collar people just trying to survive.

    I was very skeptical when I clicked on this link. Probably 75% of the people who show tig welding on youtube do not do it properly. I was very happy to see someone who is a skilled welder and educated metallurgist. I've never seen anyone weld cast iron before either, well done and hope the buisness is doing well :)

    One of the biggest reasons I chose Tig on this was to actually avoid the need to peen the weld. This stove was not the best in the world and the castings were rather thin in some areas. Hitting cast iron that was thinner than 1/8 of an inch in some spots felt a little risky to me at the time. I have mig weld cast iron dutch ovens and heavy griddles before, I just let them cool in a fire pit over a few hours. Thanks for the lead on the Jeep parts :)

    Thank you so much for the comment, I was very lucky to have a great teacher when I went to school. He showed me a lot when it came to cast iron even though it was not apart of the program. Dana is another reason I could get this job done, she is very patient with me. If not for her doing all the torch work I would have doubts about the integrity of the weld. Together we make a good team. Thanks again for the comment and for taking an interest in our channel :)

    During the preheat I try and get the temperature to approximately 400 - 450 degrees Fahrenheit or about 200 - 230 Celsius. After the weld using the propane torch we try to keep it close to 900 degrees Fahrenheit (480C). We slowly lower the temp back to 400F by lowering the intensity of the torch. After that we just let it come to room temperature on our stove over several hours.

    You can weld it with mig also. Same wire and gas as you would mild steel. I used Lincoln wire ER70S-6 wire and C25. V out the crack well, heat the part evenly in the bbq grill, weld in passes peening between each, return to the bbq grill, and shut it off with the lid closed to cool slowly. If you want to get some cheap practice in go down to a salvage yard and search for Jeep Cherokee exhaust manifolds, they are usually cracked.

    There are a couple of good reasons why TIG is not used with cast iron welding, it often has high micro porosity levels. It imparts no fluxing or cleaning to the weld pool as with Electrode welding. The process is slower and localised heat input is generally higher than any other electric based welding process giving additional contraction cracking potential.

    That's interesting and all, but I did go to school and have been doing this for my customers for years. I've never had a part returned. If you know what your doing TIG is ideal for cast iron parts repair. I wonder what your gonna think when I post my TIG Brazing video where I am going to braze copper together using a Tig torch and a silicone bronze rod.

    this was very interesting and i'm wondering if you puddle the rod as it melts or do you actually start a puddle using the iron? or do you just get it hot enough to melt the rod like in brazing?

  • @jeffreysanto

    @jeffreysanto

    9 жыл бұрын

    In this process I start a puddle when using the nickle rod. The quality of the casting also determines how the puddle forms, sometimes you get voids or air pockets in the cast that turn into mini sink holes while your running a bead. When that happens I stop, cut that section out with a grinder clean it and restart the bead. You can braze it but you need to use a bronze rod.

    To be honest it was so long ago I do not remember, I know that they were Techalloy 55 rods made by Lincoln Electric. I looked them up online but did not see anything regarding polarity. Here is a link to the product: www.lincolnelectric.com/en-za/Consumables/Pages/product.aspx?product=Products_Consumable_NickelAlloys-Techalloy-Techalloy55-TIG(LincolnElectric) I would suggest asking your welding supplier just to be sure.

    I used the propane torch to both preheat the cast iron and to maintain the temperature of the door in between welding passes. The torch itself is the same kind you would use for soldering copper pipe together. I had it on as high as it would go for the welding but then tapered the flame lower and lower to slowly cool it down. For the TIG torch I used for the actual welding process I have the regulator set to about 25 CFH. This is the same setting I have been using ever since I left school, the only time I change it is if I switch my cup size. Sometimes I need a smaller cup to get into tight places and I'll lower my gas pressure to 15 - 20 CFH.

    Try reading what I typed again... You always use 100% argon, unless you don't. And the times you don't use 100% argon, is when you as a welder knows exactly what mix you need for the task at hand (as an advanced weldor) deciding to use AR/He mixes or straight HE. I quite literally said exactly what you said, you just didn't understand. I keep a small 40cf ar/he bottle for when I need it.
