Abstract: The present invention provides a method for welding and heat-treating seam-welded constructions of hardenable steel and ferrous alloys with reduced weld-zone hardness and improved weld-zone ductility and toughness. This method consists of controlling the cooling rate of the seam weld with a secondary heat source, applied after the weld cools below the materials upper critical temperature (AC3), but prior to the weld cooling to ambient temperature. This invention is particularly suited to the production of high strength hardenable alloy seam-welded pipe and tubing.

Abstract: After measuring the bulk resistance the surface of high strength low alloy steel material is treated to form a high resistance coating on its surface. When resistance welding the material the coating permits weld formation without significant expulsion or excessive electrode force over a wide range of operating conditions.

Abstract: The base member 3 can be attached to and detached from a base-holding member 5 without using tools and the like. The base-holding member 5 has a positioning mechanism that decides the position of the base member 3 on the base-holding member 5. Here, a reference part that decides the position of the base member 3 on the base-holding member 5 in a direction parallel to an optical fiber installation surface 2, which is an upper surface of the base member 3, is called a horizontal positioning reference part. Also, a reference part that decides the position of the base member 3 on the base-holding member in a direction vertical to the optical fiber installation surface 2 (the direction vertical to the horizontal positioning reference part), which is the upper surface of the base member 3, is called a vertical positioning reference part 6. That is, the horizontal positioning reference part and the vertical positioning reference part 6 are provided on the base-holding member 5.
