projection welding

projection welding
Рельефная сварка.
Процесс электрической сварки сопротивлением, при которой происходит соединение металлов за счет нагрева электрическим током, проходящим через детали, соединяемые вместе под давлением между электродами. Площадь сварного соединения предопределена точками соприкосновения поверхностей.
