In a metal honeycomb-shaped catalyzer carrier, a corrugated portionis formed on one sidein the longitudinal direction of a metallic thin belt plate. A plurality of belt plates, . . . are alternately stacked such that a flat plate portionon the other sideof another belt plateis superimposed on the corrugated portion, and are wound from their central flat portionin the longitudinal direction thereby to form a wound honeycomb-shaped carrier body. The wound honeycomb carrier bodyis fit in a hollow cylindrical member. The central flat portionof the belt plate is wound so as to form a central cylindrical portionhaving diameter of D, and length of the central flat portion in the longitudinal is at least 4.14 D.

A method of manufacturing a cylindrical body, comprising the step of forming the cylindrical body by bending a plate-like work having first projected finger to fourth projected finger at four corned parts and allowing the end faces thereof to abut on each other, wherein the main surface of the cylindrical body on the side where sags are present is formed in an outer peripheral wall surface and the rear surface thereof on the side where the burrs are present is formed in an inner peripheral wall surface, and a first projected part is formed of the first projected finger and the third projected finger and a second projected part is formed of the second projected finger and the fourth projected finger. After the cylindrical body is held by friction stir welding devices, the probe of a friction stir welding tool is buried from the direction of either of the first projected part and the second projected part, and scanned in the direction of the other of the second projected part and the first projected part. The probe is buried and scanned in the state of being displaced to an advancing side.

In order to prevent an electrode tip 8 from being burred during dressing process, thereby attaining high quality and stability of the electrode tip, a tip dresser features a screw-threaded circumference 5 formed around the rotatable cutter holder 1 for securing a one- or two-piece formed cutter element 2, for permitting the holder 1 to be rotated in one direction A manually or by a suitable driver. Frusto-conical recesses are symmetrically formed in both sides of the holder 1 for receiving the electrode tips, allowing the cutter element 2 to be mounted so as to slightly extend by a predetermined amount beyond the conically recessed surface. Another feature is in the form of apertures 6 and 7 provided through the holder 1 for discharging the cutting chips: one aperture 6 formed on the forward front side of the rotating direction of one machining edge 2a for the bevel surface of electrode tip 8, and another one 7 on the forward front side of rotating direction of another machining edge 2b for the end surface machining. The aperture 6 is formed along the edge 2a, and aperture 7 is formed so as to reach at least the boundary between the bottom and the conical side surface of each of the frusto-conical recesses.

An improved tip dressing process is provided wherein the pressure between the electrode tip of a resistance welder and the cutter of a tip dresser is varied during the tip dressing process. A pressure controller is also provided for controlling the pressure between the electrode tip and cutter during the tip dressing process.

Pressure controller and pressure control method for resistance welder

In an electrode tip dressing apparatus, a relatively weak pressure is applied on an electrode tip at the electrode setting, then a strong pressure is applied at finishing, and finally a lowered pressure is applied after a predetermined time period. The blade holder is provided with a clearance over the entire length of the blade for discharging the chips produced during machining of the electrode tip, thereby preventing blinding of blades caused by cutting chips.

Dressing apparatus for an electrode tip

The present invention is directed to presenting rotative cutting tool of tip dresser. The blade to cut and repair side surface and/or edge surface of welding electrode tip is mounted in the holder with first tapered portion having the same angle of the blade to cut side surface of the electrode tip and second tapered portion having angle a little different from the first tapered angle in a recess of frustconical shape of the holder, said holder being provided with empty space so as to expel every cut powder of electrode tips generated in cutting and repairing operation from the recess of frustconical shape of the holder and tip of the blade has a small roundness or chamfer finishing.
