A. E11XT with a minimum impact strength of 20 ft-1bs at 0℉ B. E10XT C. E8XT D. E8XT with a minimum impact strength of 20 ft-1bs at -18℃ E. None of the above
The filler metal classification has to be E10XT. Filler material for welding is important. There are different types of materials that can be used in order to create welds. These different materials are usually classified into different categories. There are some materials that can make the materials look welded.
Some look brazed, and there are also some that look soldered. It will depend on the look that you are going for. Based on the classifications above, letter B is the best option for the whole process and the materials that will be used. Take note that the thickness of the material is also another deciding factor on the type of metal classification that will be used.
