<p>PURPOSE:To attain uniform melting of alloy components at the time of melting, by placing a granular mixture containing Ti and low-m.p. metals in a tubular body of Ti-base material, by disposing formed bodies of Ti-base material at both end faces of the tubular body to form a briquette, and then by joining the above plural briquettes. CONSTITUTION:The granular mixture 9 containing Ti and low-m.p. metals, such as Al, etc., is held in the hollow part of the tubular body 8 composed of Ti of Ti-alloy (excluding alloys of Ti and above-mentioned low-m.p. metals) sheet inside a die 1. Further, the formed bodies of Ti or the same alloys as mentioned above, such as spongy titanium 3, are disposed at both of the upper and lower end faces of the tubular body 8, respectively. Such a structure is subjected to cold cladding in the axial direction by means of a piston 5 so as to be formed into a briquette 6. Then plural briquettes 6 are connected in the longitudinal direction and welded to be formed into a consumable electrode 7. Though relatively large amounts of low-m.p. metals are contained in this electrode, alloy components can be uniformly melted at the time of melting the electrode and, moreover, the weldability of the briquettes is not inhibited.</p> |
