We have done some episodes in the past about welding Cast Iron. We know Cast Iron is difficult to weld, because it is difficult to determine exactly what materials are contained in the cast, which cause each project to react differently. In this episode of TIG Time we will show you some tricks of the trade to welding very old Cast Iron, in this case the material is 115 years old.

Super Missile Weld is a filler material that is like and used by a lot of fabricators and welders. One of the things people like about it is how the final weld turns out. You generally get nice looking beads with this filler.

What a lot of welders and fabricators don't know, is that "Super Missile Weld" is actually just a fancy name for 312 Stainless Steel. So, when you weld with Stainless Steel, you also need to remember about purging the backside of your weld if it is a critical part. If it is a static part, where 100% strength is not needed, you will likely be okay.

So lets test it out and see what kind of results we can get.

Welding different material thicknesses together can be difficult. The obvious reason is because it takes more heat to melt the thicker material, making it easy to blow holes in the thinner material. This can be especially difficult when the materials being welded are tubes. Welding mismatched tubes or flanges comes up often in both hobbyist type work, as well as in industry. There are a few things you can do to insure that you get quality welds with any undercut, holes and other common problems faced when welding this type of work.

In this video, you will learn a few techniques and trick of the trade to get your next project done quickly and correctly. Whether you are working in your garage welding a home project or welding thousands of pieces on a turntable, this video will help you master your craft.
