Mild steel filler metals offer the advantage of additional crack resistance due to their ductility but the resulting weld. New fabrication is typically performed on material in the annealed or normalized condition. Source: The filler metal recommended for welding 4140 steel is ER80S-D2. Average CVN impact energy on Flash Bainite vs. Post-weld FB tensile specimens failed at/near the interface of weld metal / base metal. Source: Generally it is recommended to weld 4130 in the annealed condition. Note non-uniformity of the ER120 welds without post-weld heat treatment. Source: Pre-heat both the shaft and plate to 600-800 degrees F use stainless 300 series rod cover with insulation blanket or warm sand to slow cool. ![]() Source: If you decide to go that route there is no reason not to have the entire link ht. Source: Ad Improve Your Business ROI - Get A Better Deal On Welding Rod. Its not recommended to weld 4130 or 4140 steel in the quench and tempered or case-hardened conditions without first performing annealing or normalizing in the area to be welded. Is purging going to solve this or is that just delaying the inevitable. Also what is the best type of filler rod to use when welding 4130 to 4130. Low-hydrogen electrodes minimize the amount of diffusible hydrogen in the weld. Abrasion-resistant AR steel plate typically is more resistant to abrasive wear than steel or low-alloy steel plate so its often used in heavy equipment and mining equipment applications. ![]() General guidelines as Ive not done the specific weld you asked about. Welding Question Welding 4130 Steel To Other Metal from Select a filler metal. Do I need to do anything differently when welding 4130 compared to mild steel. While I feel this is a total bullshit way to do it to each his own.
