tig or mig depending on the wall thickness
Copper to copper is either soft soldered, or silver soldered
Silver solder is a bad term as "solder" normally means lead content according to the AWS
Gi weld not recommended . Because of gi coationg will be spoiled out . Puncture will be occur on the pipe weld .
A butt weld is where the diameter of the pipes welded together are the same, a socket weld is where a larger diameter pipe is fitted into a smaller one. In making a butt weld, the pipes (or pipe and fitting) usually have an angle machined or ground into the outside corner, so when they are placed together face-face, there is a circumferential V shaped gap serving as the weld prep. In a socket weld, the pipe is inserted into the socket, backed off slightly to make a gap between the end of the pipe and the bottom of the socket, and the weld is made around the outside diameter of the socket to the outside diameter of the pipe. The gap at the bottom of the pipe prevents thermal expansion from stressing the joint during or after welding.
you solder or braze it
Are the joints brazed or soldered? What diameter is the tubing? When you say copper are you asking type K, L ,M , DWV , M or TP
By placing a smaller pipe insider the larger one and weld /braze the gap
Yes
Gi weld not recommended . Because of gi coationg will be spoiled out . Puncture will be occur on the pipe weld .
Very likely to leak, zinc in the GI pipe will be contaiminating the weld and thus you cannot get a good weld.
A weldolet is a fitting you weld on a (run) pipe, and then butt weld a branch pipe to it. A tredolet is a fitting you weld on a (run) pipe, and then screw a threaded branch pipe to it. Some people call this a threadolet A sockolet is a fitting you weld on a (run) pipe, and then socket weld a branch pipe to it. A nipolet is the same as a weldolet or thredolet but has an elongated branch connection. You have to specify if it's a welded or threaded nipolet.
Copper pipe is almost pure copper manufactured to the requirements of ASTM B 42 - Standard Specification for Seamless Copper Pipe, Standard Sizes. It may be manufactured from any of five (5) copper alloys (C10200, C10300, C10800, C12000, C12200) that all conform to the chemical composition requirements of alloys containing a minimum of 99.9% Copper (Cu) and a maximum of 0.04% Phosphorous (P). Available sizes are 1/8" to 12" diameters in regular wall thickness and 1/8" to 10" in extra strong wall thickness. The standard length for copper pipe is 12 feet. Copper pipe is suitable for plumbing, boiler feed lines, refrigeration and for similar purposes.Joints in seamless copper pipe can be threaded, flanged or brazed to fittings of the appropriate joint configuration.

The pipe must be fixed (not rolled) in the horizontal position. With the pipe horizontal, the weld is vertical. The pipe being fixed requires the welder to weld flat (top), vertical (sides), and overhead (bottom). The pipe must be fixed (not rolled) in the horizontal position.

wildly welding main pipe the are fillet weld or butweld
the best thing for a swamp cooler leak, is a copper pipe, or plumbing sealant, its similar to jb weld, only its waterproof, and made for leaks.

A copper pipe is a conductor :) x
