I need to build up the edges on numerous small pieces of what appears to be White Iron. Parts are roughly 2" x 3" x 1/2". Specs are as follows from met spectrograph:
2.39 C .45 Mn .50 Si .28 Ni
29.27 Cr .65 V .87 Co
Metal has huge carbides and a strong martensite structure, combined with the analysis which gives the part abrasion and corrosion resistance. The abrasion resistance and second, impact resistance, are the desired qualities.
Can anyone recommend the proper filler rod to use for tig welding the part edges? They only require .100" at most before finish grinding, with one area requiring .150" bead buildup 1/4" long. Thanks in advance for all input.
