Summary:PROBLEM TO BE SOLVED: To provide a welding material in which the weld zone of steel having excellent weather resistance has excellent seashore weather resistance in high flying salt content environment. SOLUTION: In the welding material for welding weather resistant steel used in high flying salt content environment, the deposited metal has a chemical composition containing, by mass, 0.05 to 1.00% Cu, 0.20 to 5.00% Ni, 0.10 to 1.50% Cr and 0.05 to 1.00% Mo, and also, Peq obtained by the following formula (1) is 1.5 to 4.0%, and Ceq obtained by the formula (2) is 0.30 to 0.55%: Peq= Cu(%)+Ni(%)+Cr(%)+Mo(%) (1), and Ceq=C(%)+Mn(%)/6+Si(%)/24+ Ni(%)/40+Cr(%)/5+Mo(%)/4 (2).
