    摘要: A welder containing a weld part, a clamp and a number of tools that is for welding metal wires end-to-end to one another. The tools have a tool indicator that is either in complete or in non-complete condition, and can be processing tools used to finish the weld or testing tools allowing testing the weld once finished. Before starting the welding the first metal wire is held in the clamp. By that action all tool indicators are set to the non-complete condition. When a processing tool has been used, its processing tool indicator is set to complete. When the weld has passed the specification of a testing tool, the testing tool indicator is set to complete. When each processing and testing tool indicator is set to complete the clamp will open. In this case it is sure that the operator has done all necessary steps and checks on the weld.

    摘要: The invention relates to a method for forming a laser-welded connection, in which two parts to be joined (11; 11a, 12; 12a) are connected to one another under the effect of a laser beam (1) in a joining region (30; 30a) to form a weld (2), wherein one part to be joined (11; 11a) consists of a material transparent to laser radiation and the other part to be joined (12; 12a) consists of a material absorbent to laser radiation, and wherein the two parts to be joined (11; 11a, 12; 12a) form a receptacle (25; 25a; 25b) for a component (13; 13a; 13b; 14) separate from the parts to be joined (11; 11a, 12; 12a).

    摘要: A wire for gas-shielded arc welding includes, based on a total mass of the wire: C: 0.01 mass % or more and 0.10 mass % or less, Si: 0.05 mass % or more and 0.55 mass % or less, Mn: 1.60 mass % or more and 2.40 mass % or less, Ti: 0.05 mass % or more and 0.25 mass % or less, Cu: 0.01 mass % or more and 0.30 mass % or less, S: 0.001 mass % or more and 0.020 mass % or less, N: 0.0045 mass % or more and 0.0150 mass % or less, Al: 0.10 mass % or less, and P: 0.025 mass % or less, with the remainder being Fe and inevitable impurities. In the wire, the following relationship is satisfied: 0.1≤[Ti]/[Si]≤3.0, where [Si] is the content of Si (mass %) and [Ti] is the content of Ti (mass %).
