Title: Composite tab material used for high heat input submerged arc welding of thick steel plate
Inventor: SAKAGUCHI SHUICHI
IPC: B23K37/06
Filed: 1990-11-30
Abstract: PURPOSE:To simplify handling of a tab in high heat input submerged arc welding of the extremely thick steel plate by constituting the composite tab material of a jig to hold steel material to be subjected to arc on an extension line of a groove edge of steel material to be welded via refractory members. CONSTITUTION:The steel material 1 to be subjected to arc is set on the channel bottom of the recessed refractory members 2. Consequently, a recessed channel 4 is formed of the upper surface of the steel material 1 to be subjected to arc and walls of the refractory members 2 at both sides. As a result, working of the groove channel of the steel material 1 to be subjected becomes unnecessary. In addition, since the refractory members 2 holds the steel material 1 to be subjected to arc from both sides while being held by the jig having a recessed cross section made of steel, etc., it is not necessary to form it into an integral substance having the recessed cross section. Since the jig 3 holds the refractory members 2 and the steel material 1 to be subjected to arc on the extension line of a groove 23 of a box support 10, it is fitted to an end of the box 10 support by tack welding, etc., and protected from molten metal by the refractory members 2, hence it can be used semipermanently.
