Dec3 Contest ~ Project 1 ~ From I Love Plasma Wear Pad Over-Haul
Well, some wear out the cutting edge wear bar and some wear out their wear pads, in hopes of lengthening the life of their wear bar.
My dad is a wear pad guy.:rolleyes:
Here is the over haul on one of the snow blower wear pads that I did. It took about 35 minutes to complete. 23, E7018, 1/8", baked rods (1.4LBS). (Baked rods are very nice, especially when they are still hot right out of the oven.) Running spot tacks a 78 amps on my Power Arc 200, then for the actual welding I used a nice 122 amps so I could just lay in steel fast, and it's a pretty fluidity puddle, gives room for minor bumps or jiggles from operator error. haha.
This pad had completely worn off, leaving a post and a doughnut shaped disc. The hole in the disc was roughly a quarter inch larger than the rod and the edge was tapered down to nothing. So I took a scrap piece that would span the hole in the disc, and welded it to the post (like a "T" shape). Then I put the disc on the shaft tacked it from the top side. Next I turned it over and fully welded and built up the bottom side of the pad. After doing this I did two passes on the inside of the pad.
Here are some pictures, sorry I did not take then with my good camera. Cell phones :confused: nice....not LOL. Sorry forgot to take a picture of how it looked before welding.

Nice big chunks of slag, and no slag inclusions with my new PowerArc200 and a better technique.
