Here's the relevant quote:
These inserts are best described as sections of material
that are comprised of one part aluminum with another
material already bonded to the aluminum. The method
used for bonding these dissimilar materials together, and
thus forming the bimetallic transition, are usually rolling,
explosion welding, friction welding, flash welding or
hot pressure welding, and not arc welding.
The original question was "Is it possible to weld aluminium to steel".
and the quote above says the "explosion welding", "friction welding" or
"hot pressure welding" can be used to weld AL to steel, so the answer is
"yes, 4 different types of welding can be used to weld AL to steel".
Arc welding is only one welding method and wasn't specifically asked in
the question, so the answer must cover all welding methods.
