Question

could anyone explain the difference bn by and through (especially to say how something is performed)
for example:
1.metals are joined by welding
2.metals are joined through welding.
please get it correctly I'm asking about by and through not about welding,some punk answered about welding​

Answer 1

Answer:

The main difference between Through and By is, Through refers to a process while By refers to means of something. Through refers to the location from one point to another across a medium while By gives a location that is next to or past beyond something

In the 1st sentence by is referring the means by the work is done

where as

In 2nd sentence through is referring to a process know as welding

hope it will help you !
