New wording Goblin Welder announced.

[Zieby]

Goblin Welder
New Oracle text:
{oT}: Choose target artifact a player controls and target artifact card in that player's graveyard. If both targets are still legal as this ability resolves, that player simultaneously sacrifices the artifact and returns the artifact card to play.

I fail to see the how this is significant? Functunaly there's no difference.

Because both happen at the same time.  Before, it was worded as 'then return'.  I don't know exactly how significant this is, but there has to be a reason for it.  I...just don't know what yet.

means for instance you won't be able anymore to use welder on sensei's divining top, use top's draw ability in response, and still get the artifact back from the grave as you could before.

I fail to see how this prevents that.  If you tap top, then weld it in response for [INSERT ROBOT HERE], you should still draw a card.  It's still a legal target--putting top on top is part of the effect, not the cost.

I may be wrong on this but as far as I know this was also not possible before the new wording.
Destroying the in-play artifact in response to the Welder activation also prevented the Welder ability from resolving (returning the in-grave artifact to play).

[zeus-online]

You really should still be able to draw cards with welder/top...And you can still fizzle the welder activation with graveyard hate or artifact destruction.
So what's the difference?

There is absolutly no fonctionnal change with this new wording. It works exactly as it used to work.
The Top/Welder trick allways worked, and still works.

Gottleib said in the wizards.com column that they did some functionnal changes (such as time vault) and non functionnal changes (just to let all the cards that got the same kind of effects have the same wording) and welder is one of those changes.

@Tobi : I think that the trick isn't well explained... If you activate top after welder, the exchange fails because as you said the in play artefact have to still be in played at resolution or exchange fails( Same applies for the graveyard artefact). You have to Activate top first, then weld it out to bring back an artefact, and draw a card.

that trick seems to be more secret than i guessed. (i have met a lot decent players in our vintage scene that were not used to it and it took me some time to convince them that it works)

put the draw ability of the top on the stack. activate the welder to exchange the top (still in play) with some artifact from the grave. result is a top in the yard, robot in play and you have +1 card.

i dont see the new wording preventing this.

[theLastGnu]

I think the new wording is just to clarify that the artifact goes on top of the graveyard rather than where the other artifact was.

[Neonico]

Mostly to bed worded as all permanents exchange cards are worded i guess....
