摘要： PURPOSE:To carry out a high quality welding by applying a high density current between a plated steel material and a clad material in a resistance welding method being suitable to a spot welding between the steel material executing a corrosion preventing treatment, etc., with a plating work and an aluminum base material. CONSTITUTION:The clad material 15 composed of an iron layer 15a having projecting parts 15c and an aluminum layer 15b is interposed between the plated steel plate 13 as a material to be welded and the aluminum steel plate 14. A specified current is applied to the electrodes 10, 11 from AC electric source 15b. Electric conducting passage of the welding current is limited to the area of the projecting parts 15c, and as molten plating metal by melting the plating layer 13a is incorporated among the pitches of the projecting parts 15c, the enlargement of the electric current conducting area is prevented. In this result, the temp. of the interface between the plated steel plate and the clad material is efficiently raised and the suitable nugget is formed to both surfaces of the clad material 15.

摘要： PURPOSE:To keep the high strength of a joint in the wide current range by using the iron/aluminum clad of the prescribed ratio of the thickness of a sheet made of aluminum to that of the steel sheet. CONSTITUTION:A galvanized steel sheet 1 is arranged on the iron side c>f a clad sheet of double layer of iron/aluminum made of a cold-rolled steel sheet 3 and an aluminum sheet 4, and an aluminum sheet 2 is arranged on the aluminum sheet 4 side to execute the spot welding. The iron/aluminum clad sheet where the ratio of the thickness of the aluminum sheet to that of the steel sheet is 1:1.3-1:5.0 is used, and the welding is executed under the condition where the welding current is 7.5-15.5A, and the welding time is 80-280ms. This constitution suppresses the deposition of the aluminum and the plating to the minimum, and high strength of the joint can be secured.

摘要： PROBLEM TO BE SOLVED: To reliably prevent any welding defect in the lap welding of plates by correctly measuring the space between the plates in the lap welding, and performing an adequate welding work based on the result of measurement.
SOLUTION: The vibration generated by a vibration generator 3 is given to non-welded portions of plates W
1 and W
2 by a vibration transmission roller 4, and the vibration given to the plates W
1 and W
2 is detected by a pickup sensor 5. When the vibration given to the non-welded portions of the plates W
1 and W
2 is detected via the plates, the frequency detected according to the space between the plates becomes different, and by utilizing this fact, the space between the plates immediately before the welding is obtained by referring the detected frequency to the correlation between the pre-grasped space between plates and the detected frequency by an analyzing means 6. The pressure to the plates W
1 and W
2 by a press roller 9 is adjusted according to the correct space between the plates immediately before the welding.
