Abstract

trata-se de técnicas de soldagem, incluindo, por exemplo, soldagem por resistência a ponto, que podem ser usadas para unir ou soldar duas ou mais chapas de metal juntas. uma força de aperto (204) e uma corrente elétrica (212) podem ser aplicadas a duas ou mais chapas para criar fusão localizada que combina o material das duas chapas. aplicar uma força de aperto (204) e uma corrente de resfriamento (224) pode incluir diminuir gradualmente a quantidade da corrente elétrica aplicada à solda enquanto se aplica a força de forjamento. ajustando-se a quantidade da corrente elétrica aplicada à solda pode permitir que a solda resfrie gradualmente, o que pode reduzir tensões térmicas e permitir que a força de forjamento feche fissuras, poros, ou seja usada, de outra forma, para remover ou evitar defeitos (102) formados na solda.
