摘要： PROBLEM TO BE SOLVED: To improve weld quality by preventing the fluctuation of a welding voltage and a defective arc start when starting welding, which are caused by the fluctuation of a heat input during the welding and a short circuit between molten metal at the tip of a steel bar and a molten pool on a steel plate in a welding method for the steel bar having a large diameter in a submerged arc press welding method. SOLUTION: By calculating the heat input based on a welding current and the welding voltage during the welding, and making a welding heat input constant by finishing the welding when the heat input has reached a prescribed welding heat input controlling the heights of the steel bars so that the welding voltage during the welding becomes a prescribed value and controlling the heights of the steel bars so that the welding voltage becomes a prescribed value even when fails to start the welding, an arc is made to start again.

摘要： PROBLEM TO BE SOLVED: To obtain a welding method having high welding quality capable of optimally controlling a position of a bar steel during the generation of an arc and a thrusting quantity after that according to individual welding states. SOLUTION: In a welding for a bar steel wherein a welding arc is generated between the bar steel and a steel plate, the bar steel and the steel plate are heated with the welding arc to partially melt them, and thereafter welding is executed by thrusting the bar steel into the steel plate, an arc voltage when the arc is generated is measured, a thrusting quantity of the bar steel is obtained from a linear expression of a measured value of the arc voltage showed as follows. d=a×V+b Here, the thrusting quantity is expressed by (d) and the arc voltage is expressed by V. Moreover, (a) and (b) are a proportional constant and preliminarily obtained prior to welding.
