The wire has such a structure as not to be plated with copper on the surface thereof.
摘要:
A plating-free solid wire for arc welding has pits opening on its circumference, and wider inside than at each opening, and/or pits having a portion non-irradiated with an externally incoming light. A sulfide and a polyisobutene-containing oil are present in the pits and/or on the wire surface, the latter being present in an amount of 0.1-2 g/10 kg of wire. Twenty or more pits are present in total per and along wire circumference. The effective pit length ratio is 0.5% inclusive-50% exclusive. 0.1-2 g of the oil is present per 10 kg of wire. 0.01-0.5 g/10 kg of 0.1-10-&mgr;m-particle-dia MoS2 is present in “bottleneck-like and/or cave-like pits”, on the wire surface or immediately under the wire surface. A 2-10 mass ppm/total wire mass of K compound in K is present in the pits and/or on the wire surface. These ensure good feedability and lubricating properties, and less spatters.

A welding wire of the type consists of a plated or uncovered solid wire and a flux-cored wire for carbon steel or stainless steel, wherein one or more of hydrocarbon compounds selected from the group consisting of saturated or unsaturated hydrocarbon compounds, which have from 5 to 12 carbon atoms and a linear or branched structure, and hydrocarbon compounds having a cyclic structure are deposited on a wire surface. A lubricating oil and/or lubricating particles are chemically combined with a wire surface through the one or more hydrocarbon compounds. The total amount of the hydrocarbon compounds, and a lubricating oil and/or lubricating particles deposited on the wire surface is in the range of 0.1 to 5 g per 10 kg of the wire.

摘要:
An object of the present invention is to provide a system that allows a user to preset a desired TV program for unattended recording by use of a PDA. A PDA acquires from a TV program information service provider TV program information by which to preset a desired TV program to be recorded unattended. When the user selects relevant TV information about the desired program, the PDA sends to a personal computer the information for presetting the TV program of interest for subsequent unattended recording. Based on the preset information sent from the PDA, the personal computer presets the specified TV program to be recorded unattended.
