Actually it isn't always the best method, but it is quick and inexpensive to do making it a very popular choice for electronic connections.
In high vibration and/or high thermal stress environments spot welding of the component leads is a much better method of making electronic connections.
why do you think its best for soldering iron to have soldering stand

It is not recommended to use expired liquid flux for soldering as the effectiveness of the flux diminishes over time, which can lead to poor soldering results. It is best to use fresh flux to ensure proper soldering and avoid issues such as weak joints or oxidation. Expired flux may also contain harmful chemicals that could pose health risks during soldering.

Wave flow soldering is a method of soldering all the connections on a printed circuit board in a single step on a machine (instead of one at a time by hand).A wave flow soldering machine has the following parts:a heated tank containing molten solder covered with a thin layer of fluxone or more printed circuit board fixturesa mechanical wave generatorPrinted circuit boards are populated with components (on automatic part placement machines and/or manually by human assemblers). The populated printed circuit boards are placed in the fixtures. As each fixture goes into the wave flow soldering machine the wave generator sends a wave of solder down the length of the heated tank. The top of this wave just touches the bottom of the printed circuit board, soldering all the connections. After the fixtures leave the wave flow soldering machine they are allowed to cool a while and the printed circuit boards are removed.The soldered printed circuit boards are then washed to remove any flux residue left by the wave soldering machine, then sent to be tested to make sure they function as intended.Wave flow soldering works best for "through hole mounted" components.
Poor electrical connections due to poor design or construction. Mine went bad soon after I bought mine. First tried soldering a few connections, but this was a temp fix at best. Best bet is to replace with an aftermarket one. They're inexpensive today.
Soldering irons and soldering stations range in price from around $10 upwards. The best soldering irons are usually industrial ones, however these may not be required for home use.
Soldering irons are designed to heat up the lead in solder to its melting point, allowing it to flow and create electrical connections. The high temperature of the soldering iron transfers heat to the lead in the solder, causing it to melt and bond with the materials being soldered.
Soldering guns are used where more heat is needed than from the lower-power soldering irons. They can be used for heavy electrical connections, stained glass assembly, and light sheet-metal work. Typical soldering guns are rated at 100 to 240 watts power. A gun may include a two-stage trigger to give two heat settings 📷
Dry joints can occur due to insufficient soldering during the assembly process, leading to poor electrical connections. Other causes can include excessive heat during soldering, contamination on the soldering surface, or using the wrong type of solder alloy. Dry joints can lead to unreliable connections, increased resistance, and eventual failure of the electronic component.
1.4 Soldering Methods1.4.1. Hand soldering: It is the oldest method of soldering, it is still popular method in certain kinds kinds of applications:Development of prototype boardsLow volume productionSoldering of extremely temperature sensitive componentsSolder reflow of fine pitch components using hot barRework or repair of machine soldered boardsThe main disadvantages are operator training, speed, and consistent quality.1.4.2 Machine Soldering:Two prominently used machine soldering types are:A. Wave Soldering - Primarily used for soldering through-hole components on to PCBs.B. Reflow Soldering. - Used for soldering SMD components on to PCBs. Reflow soldering of SM components have the following advantages over manual soldering:Mass solderingConsistency in manufacture through precise control of process parameters.flexible for small production runs as well.
Because when in use the tip is warm and can burn and mar stuff if you just put it down.
