Title:
Ti WELDING WIRE AND WELDING METHOD
Document Type and Number:
Japanese Patent JP2002144083
Kind Code:
A
Abstract:
To provide a welding technique by which, in MIG welding of Ti, wire feedability is good, thus, arc is made stable, further, sputtering is little, and a good bead can be given.
MIG welding is performed by using a Ti welding wire in which pure Ti is used as the material, in the relation with a contact tip of a welding device, the ratio between the diameter Dw of the welding wire and the inside diameter Dc of the contact tip lies in the range of Dc/Dw=1.1 to 1.4, tensile strength lies in the range of 400 to 800 N/mm2, and the maximum surface roughness Rmax in the longitudinal direction is ≤20 μm.
