WebDec 30, 2010 · I vee'ed out the outside of the crack with a carbide burr, and found it welded decently. I then reamed out the galled material from the ID of the big end, and built the material back up using 4043 filler; TIG welded using an Everlast Super200P. I did the build up first around the edges with my usual "focused arc" settings. WebSep 18, 2014 · The results obtained in the previous section give important information on the amount of galled material resulting from the test and can be expressed as a function of the applied pressure. The area of the eroded region is intuitively an important parameter, but its relevance to quantify the occurrence and amount of galling is not yet ...
