摘要： PROBLEM TO BE SOLVED: To provide a narrow groove welding device which can control a welding position so as to trace a narrow groove for preventing an occurrence of failure such as an undercut of the narrow groove wall and a poor melting.
SOLUTION: A phase delay of swinging of an arc 7 formed between a tip of welding wire 6 and a base material 3 from swinging of a welding wire oscillator 11, namely a shift cycle X, is calculated by the equation: X=60LZ/v, (wherein L:distance between a vertical position of the welding wire oscillator 11 and a vertical position of the arc 7, Z:swing cycle of the welding wire oscillator 11, v:feeding speed of the welding wire 6). The present swing position of the arc is decided based on the shift cycle X, and the correspondence between the present swing position of the arc and the welding current value or the welding voltage value is identified. Wave integrated values of the welding current or the welding voltage for a half cycle are calculated for right and left of the swing cycle of the arc 7 respectively and then the right and left positions to the arc swing center control axis U are controlled so that the difference of both values stays constant all the time.

摘要： PROBLEM TO BE SOLVED: To provide a welding structure of a header and a heat transfer tube composed of an Ni base alloy, easily performing replacement welding work of the aging heat transfer tube composed of precipitation enhancing type Ni base alloy on site in large quantity.
SOLUTION: In this welding structure of the header 1 and the heat transfer tube 4 composed of Ni base alloy in the heat transfer tube replacement work after use with the lapse of time, one end of a stub tube 2 composed of solution enhancing type nickel (Ni) base alloy, weak precipitation enhancing type (equilibrium precipitation of γ' phase of 10% or less) nickel (Ni) base alloy or high strength austenitic steel is connected to the header 1, and a new heat transfer tube 6 is connected to the other end of the stub tube 2 through a thickness adjustment piece composed of a material same as the heat transfer tube 4 in welding and connecting the boiler heat transfer tube 4 composed of γ' phase precipitation strengthening type Ni base alloy including Ti and Al, and the header 1 composed of γ' phase strengthening type Ni base alloy including Ti and Al. As the stub tube 2 of the material has a potential of weld cracking lower than that of the heat transfer tube of precipitation strengthening type Ni base alloy, as it is free from remarkable hardening and degradation of ductility even after used with the lapse of time, the welding is performed on site without performing solution treatment on the end of the stub tube before welding.
