This laser irradiation mechanism includes a control unit which has a function allowing the focal point of a laser beam to describe a circle, performs control such that the focal point describes a spiral, and performs control such that the central axis of the spiral moves along a curved surface.

Laser welding device and laser welding method

A method for assembling a metal honeycomb catalyzer carrier includes the steps of winding corrugated belt plate materials into a substantially cylindrical shape, forming a wound structure into a predetermined cylindrical shape with a dieand pushing out a wound honeycomb bodyobtained through the forming from the die and inserting the wound honeycomb bodyinto the interior of a tubular member. An assembling apparatusincludes a winding unitwhich includes, in turn, a rotational holding shaftand a press roller unit, a die unitfor forming a wound structure wound round the rotational holding shaftinto a wound honeycomb bodyof a predetermined cylindrical shape (of an outside diameter Dp), a tube support unitfor setting a tubular memberat an edge of a die surface, and a honeycomb push-out and insertion unitfor pushing out a formed structure from a dieand inserting the formed structure so pushed out into the tubular member

Assembling method for metal honeycomb-shaped catalyzer carrier and assembling apparatus for the same

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.
