sem results showed that a well-sealed disk or cylinder microelectrode was conveniently obtained with this method, and the cross-section of the electrode tip was sufficiently smooth.
the removal of non-metallic inclusion during remelting occurred mainly in stages of formation of dropets on the consumable electrode tip and dropets falling through the slag.
电渣重熔过程中非金属夹杂物的去除主要发生在自耗电极端头熔滴形成期以及熔滴滴落穿过熔渣层阶段。
effect of tic coating on electrode tip surface on electrode degradation during resistance spot welding zinc coated steel;
本文主要研究了微型点焊镀镍钢板和镍板时电极失效的机制。
the effect of the shape of electrode tip on crack formation and sticking were investigated.
研究了电极端部形状对焊点产生裂纹及粘结的影响。
the maximum lesion size was determined ultimately by the radius of the electrode tip , no matter what method was used. it is about 2.49 times the radius.
不论用哪种方法,最大损伤斑的尺寸是不变的,它仅仅与电极头半径有关,大约是半径的2.49倍。
the gripping device can be installed in the top and bottom electrode tip holders, which makes the combined work pieces spot projection welding once.
