It was manufactured through the process as shown in FIG. First, the face material 1 is distributed, and the mounting wire 3 of the web material 2 is provided on the surface thereof.
Draw a ruled line (Fig. 3 (a)). Next, the web material 2 is distributed according to the attachment lines 3 of the face material 1 (FIG. 3 (b)),
After fixing a plurality of locations in the longitudinal direction of the web material 2 to the face material 1 with T rulers and clampers (not shown) and fixing a plurality of locations of the fillet portions by tack welding 4,
Remove the ruler and clamper (Fig. 3 (c)). After that, the tack welded longe material 5 is conveyed by a crane or the like, set on the self-propelled welder 6 as shown in FIG. 3D, and then the self-propelled welder 6 is run along the rail 7. The left and right welding torches 8a, 8b simultaneously weld (main weld) 9 both sides over the entire length of the fillet portion.

発生が防止される。By the way, the longe 5 is shown in FIG.
As indicated by arrows in (a) and (b), bending due to thermal strain occurs. FIG. 4A shows a bend that occurs during welding, and the welded portion (lower portion) expands due to heating, resulting in an upward warp. Figure 4
(B) is a bend that occurs in the process of returning to normal temperature after welding, and the welded portion (lower part) contracts, resulting in warpage. Therefore,
Immediately after the main welding, the longe 5 is transferred to a heating device (not shown) by a crane or the like, and the upper portion of the web portion is heated 11 at several places along the longitudinal direction as shown in FIG. 5 (a), and is indicated by an arrow in FIG. 5 (b). As shown, the upper portion of the web portion is also expanded to remove the strain. As a result, in the process of returning to normal temperature, the upper and lower parts of the web part both shrink as shown by the arrow in FIG. 5C, and the occurrence of warpage is prevented.

Not only was it inefficient, but there was also a problem with safety. That is, in the past, the built-up longe was divided into four parts: distribution of face and web (first step) → temporary welding over the entire length (second step) → main welding (third step) → strain relief (fourth step). It was manufactured in each process, and the longi material was transferred by a crane between each process.

て、安全性の確保が容易となる。As described above, according to the present invention, the face material and the web material are arranged in an inverted T shape, and the relative positions of these are fixed to the regular position only at the tip, and the fixed type is provided by the conveyor. By simply sending it to the longi manufacturing device, the longi manufacturing device defines the relative position of the T joint portion without stopping the flow of the face material and the web material conveyed on the conveyor, and
Double-sided fillet welding (main welding) of the joint and strain relief by heating the anti-welding side edge of the web material are configured to be performed simultaneously or continuously, so the number of manufacturing steps for built-up longe is reduced compared to the conventional method. The number of processes can be substantially reduced to two, and the transfer of Longe between cranes is eliminated between the processes, which facilitates ensuring safety.
