P: He aha te rerekētanga o te whakarewa ERW i ētahi atu tikanga whakarewa?

A: He rerekē te whakarewa ERW i ētahi atu tikanga pērā i te whakarewa pewa ruku (SAW) me te whakarewa pewa hau (GMAW) nā te mea ka whakamahia te ātete hiko hei whakaputa wera mō te whakarewa. He tino whai hua tēnei tukanga, ā, ka taea te whakaputa tonu.
