る。According to this method, a pin terminal 10 made of iron / nickel alloy which is a high melting point metal and a plate-shaped terminal 11 made of brass which is a low melting point metal are resistance-welded with an alternating current 13 accompanied by preheating 12 shown in FIG. The plate-shaped terminal 11 is provided with a pair of contact curved portions 16 and 17 for the tip rounded portions 14a and 15a of the left and right electrodes 14 and 15, respectively.
17 directly heats the flexure contact 16

Even if an attempt is made to perform resistance welding with the AC current 13 accompanied by 2, the heat escapes to the stainless steel terminal side due to the large heat capacity of the stainless steel terminal, the effect of preheating cannot be obtained, and sufficient welding strength cannot be exhibited. Even if a projection projection (not shown) is provided on the brass terminal here, the low melting point projection projection is crushed by heat before the high melting point stainless steel terminal is completely heated because the energization time is long,
Welding cannot be done well.
