    Abstract: PROBLEM TO BE SOLVED: To easily and correctly evaluate the welding quality at low cost. SOLUTION: A welding quality evaluation device 1 includes a welding quality evaluating element g to be installed at a predetermined position on a surface of a member W2 to be welded, a CCD camera K as a detection means for detecting the welding quality evaluating element g, and an evaluation means PC which determines the softening or the melting of the element by recognizing the welding quality evaluating element g detected by the CCD camera K, and evaluates the welding quality based on the result of determination. The welding quality evaluating element g is formed of a low melting point material which is softened or melted at the predetermined temperature lower than the melting point of the members W1, W2 to be welded, and constituted so that its appearance is changed when the temperature reaches the predetermined value. The element is installed on the surface of the member W2 at least one of the position of a part M at which the temperature is raised to the value for changing the appearance when the normal welding is executed and the position at which the temperature is maintained at the value for not changing the appearance.

    Abstract: PROBLEM TO BE SOLVED: To suppress weld defects such as blow hole caused by the gasification of a coating material between coated steel plates at the welding time without needing troublesome and difficult gap control. SOLUTION: In the lap welding method for galvanized steel plates 1, Cu-base filler metal 4 as a low melting point filler metal is mixed into fused pool 7. In this way, the temperature at the portion in contact with galvanized layers 2 between both steel plates 1 being the outer peripheral zone in the fused pool 7 is controlled to not higher than the boiling point of Zn. The Zn in the galvanized layer in contact with the outermost periphery of the fused pool 7 is only melted and not boiled. Therefore, gas volume produced by gasifying the galvanized layer 2 between both steel plates 1 is reduced and thus, the gas volume invaded into the fused pool 7 can be reduced. Further, since the advancing direction of Zn vapor in the fused pool 7 is obstructed with the welded part 6 formed by quickly solidifying the fused pool 7, the Zn vapor quickly gets out from the fused pool 7 without beingnot stayed in the fused pool 7.
