|Chapter 5. Weldings and Soldering|
Outline of Welding
Kinds of the Weldings
Welding is processing which melts the metal materials with hot heat, and ithey are joined. There are various kinds of the welding depending on how to give heat. An arc welding is used most often as a welding process of steel material. For welding of a comparatively thin plates, it is easy to treat a gas welding. A TIG welding is used for welding of stainless steel or an aluminium alloy.
A soldering is the joining method similar to the weldings, without melting the material itself, it melts only a solder. And it joins to metal materials. The soldering. has a low temperature at the processing compared with the weldings, then it is easy processing.
