Hi, new guy to welding here, just got started with gas welding (oxy/ace) and I'm discovering that i need to build a few tools in order to get started. One is a corner clamp/jig and the other is a welding table.

I've lurked around for a while and found out that its not good to weld the top of the welding table to the legs because it might cause heat distortion to the top. Of all the pictures of everyone's welding table i have seen on this forum, it seems that almost everyone just put a little tack every few inches apart, just enough to make the legs and top stick. Is this the standard procedure? or am I missing something? Am i correct to say that I want to minimize heating the top piece?

I'll make some corner jigs before i make the table. Just have to measure 20 times before i cut/weld.
