In the marine industry, there are several cases of damage and leakage in welded seawater pipe joints in marine systems caused by corrosion processes. This comparative research is to find the filler material that is most resistant to corrosion. The filler materials tested were LB52U, RC52U, and E6013. The method used is SMAW welding using AC current and the corrosion test process using the lost weight gain (LWG) method with immersion using Hcl liquid media. The pipe specimen used is STPG370 D125 Sch80. Immersion of the specimen for 8 hours and the obtained corrosion rate value for welding on STPG370 pipe metal with air cooling media and the corrosion rate of LB52U electrode material is 1.026 mm / year, for RC52U electrode material is 0.771 mm / year, for LB52U + E-6013 electrode material is 0.767 mm / year, RC52U + E-6013 electrode material is 0.826 mm / year.
