Push-on-joint pipe vs mechanical-joint pipe?
Push on joints seal by the spigot end expanding (and thus compressing) the rubber gasket in the bell. A Mechanical joint compresses the gasket in the bell by pressing a gland follower against the gasket, by tightening bolts. They both achieve good seals when done according to makers instructions, but MJ joints are more work, and have bolts that can corrode and freeze. If there is an advantage to,MJ joints I have been unable to find it. Note: MJ joints do NOT prevent pipe pull-out. The pipe must be restrained somehow, just as with push-on. David Philips PE
What is the effect of water pressure at the pipe joints?
Water constantly exerts pressure on pipe joints. I have seen old soldered joints flying apart when subjected to extreme pressure or trains passing nearby. This sometimes happens with plastic pipe also if joints are not thoroughly set .

When saying calculating inch dia of pipe is number of welded joints x pipe size that refers to lenght of pipe or diameter of pipe?
Pipe size refers to the diameter of the pipe (in inch).
What are Pipe joins?
A pipe joint is a key component to any successful plumbing system. Pipe joints means the connection at the ends of pipes that ensures tight sealing and strength. In some cases, pipe joints must also provide for rapid assembly and dis-assembly or a change in the direction of the line of pipe. The most common types used for general-purpose metal pipes are welded, flanged, threaded, and bell-and-spigot joints. alliedallcityinc.com

How do you loosen rusted pipe joints?
I'm assuming you mean house pipe joints. Start at the pipe union, using a bigger pipe wrench if necessary. If the joint breaks you will have to replace the pipe. Unfortunately there aren't any real good tricks, it just takes a lot of force. you can try draining the pipe and adding heat, but don't get it hot enough to melt the galvanized coating otherwise you'll NEVER get the pipe off. If it's a gas pipe don't try putting heat on the line. That wouldn't be good.
6 inch weldolet welded to 12 inch pipe what is the inch dia involved?
The meaning of dia inch is the number of weld joints multiplied by the dia of a given pipe size, since the weld joints is on the 6" pipe, the calculations should be 1 weld x 6" = 6 dia inch.
