Fig. 2 is the bus-bar of the embodiment of the present invention and second of embodiment of lug.
In figure：1- bus-bars；2- lugs；3- welding grooves；4- butt welding portion.
Embodiment
The present invention is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1 to Figure 2, the present embodiment is produced using electric current by the contact surface and adjacent domain of bus-bar 1 and lug 2
Raw resistance heat is welded, and is comprised the following steps：
Step 1, solder side forming processes will be carried out with the contact surface of bus-bar 1 on lug 2, on bus-bar 1 with lug
Opened up on 2 contact surface with welding groove 3 one-to-one with lug 2；
Step 2, by the connection corresponding with welding groove 3 of the welding ends of lug 2；
Step 3, position of the bus-bar 1 with respect to lug 2 is subjected to displacement, is denoted as the first displacement；
Step 4, it is molten to be formed that energization butt welding or flash welding are carried out to the contact surface and adjacent domain of bus-bar 1 and lug 2
Core；
Step 5, power-off forging and stamping, nugget crystallisation by cooling in the case where pressure continues effect is set to form solder joint, forging and stamping distance is denoted as the
Two displacements.
Position of the bus-bar 1 with respect to lug 2 is subjected to displacement by way of extruding in the present embodiment step 3.First
Move as 1mm ~ 2mm.Second displacement is 0.5mm ~ 2mm.
As shown in Figure 1 to Figure 2, in the present embodiment step 1, solder side forming processes comprise the following steps：
First step, the erecting and welding position of all lugs 2 of required welding on a bus-bar 1 is fixed；
Second step, it will carry out being cut to butt welding portion 4 by the welding ends of fixed lug 2.
As shown in figure 1, the first embodiment in the present embodiment butt welding portion 4 is smooth plane.To bus-bar 1 in step 4
Energization butt welding is carried out with the contact surface and adjacent domain of lug 2.
As shown in Fig. 2 second of embodiment in the present embodiment butt welding portion 4 is 4 rectangular dentation of butt welding portion.It is right in step 4
