For the disjoint union, I don't like \amalg and \coprod very much. So, I did all my best to create a \varamalg with this code:

\documentclass{article}
\usepackage[utf8]{inputenc}
\usepackage{mathtools,amssymb}

\newcommand{\varamalg}{\sqcup\hspace{-1.085em}\raisebox{-.195em}{\rotatebox[origin=c]{37}{$\smallsetminus$}}}

\begin{document}

$A\varamalg B=A\cup B$

\end{document}

And I get:

enter image description here

Well, not bad for me. I used \smallsetminus because the ends are rounded.

But now, I'm not able to create \varcoprod. Could you help me?

    So by \varcoprod you're just after an operator-type \varamalg? If not, could you explain more what \varcoprod should look like, and how you plan on using it? – Werner Mar 18 '14 at 17:14
