Corrosion rates can vary between welded and non-welded metals, therefore it is advisable to study the behavior of both conditions.
由于焊接金属与非焊接金属的腐蚀速率会不同，所以有必要研究两种情况。
Electrical effect. Two different metals welded together can transform heat energy into electrical energy. This principle is used in the refinery to measure temperature by use of thermocouples.
电效应。两种不同的金属焊接在一起可以将热能转化成电能。在炼油厂，根据这一原则，通过使用热电偶来测量温度。
