Title: Steel wire for gas shielded arc welding
Inventor: SUZUKI YOZO
IPC: B23K35/02
Filed: 1994-03-29
Abstract: PURPOSE:To improve wire feedability and welding workability, to automate and robotize welding and to enhance the performance of welding by adding specific patterns at a specific area on a wire surface and further, providing a lubricant on the wire surface. CONSTITUTION:The striped patterns of 5 to 30 lines per 1n of the width in the circumferential direction having depth 0.2 to 1.07mum are added on the copper plated steel wire for automatic or semiautomatic welding in the longitudinal direction of the wire. The striped patterns are formed to 10 to 50% of the surface area of the wire and further, the wire has the lubricant on its surface. The holding capacity of the lubricant is poor and the feedability is inferior if the depth of the lines is below 0.2mum. A large amt. of the lubricant accumulates on the wire surface and the weldability is degraded and particularly many spatters are generated if the depth is over 1.0mum. Drawing is made possible by mixing hard powder with the lubricant and without decelerating the drawing speed. This steel wire is used as a simple method.
