Welding is a process where two metallic or non-metallic pieces are joined by means of high energy, as long as they are of the same or similar composition so that the joint remains rigid. We will choose the type of welding depending on the physical properties of the metals, the use to which the welded piece will be destined, and the facilities. Our guide to welding has a bit of information on each type:

Different Types of Welding Techniques in 2021
SOFT WELDING:
This type of solder is used to create joints in tinplate, galvanized sheets, brass and bronze parts, lead pipes, and electrical components.
In this type of welding, the temperature used is below 450 degrees Celsius, and an electric soldering iron is used.
STRONG WELDING:
It is a technique of thermal union, with which it will obtain connections of brass, copper, silver alloys, and steel.
The temperature ranges from 450 to 800 degrees Celsius, and a gas torch is used.
OXY ACETYLENE WELDING:
It is used for iron or steel sheet applications, mostly in use in the marine, construction, and automotive industries.
It is welded at a temperature higher than 3000 degrees Celsius, and an Oxyacetylene torch is used.
ELECTRIC RESISTANCE WELDING:
It is of great importance in modern industry, especially in sheet metal.
This welding technique is used for the manufacture of car bodies, electrical appliances, and in the electrical and toy industries.
The metals are joined without the need for filler material; only pressure an
d electric current are necessary on the areas to be welded.
ENERGY BEAM WELDING:
It is the most modern welding technique. In this type of welding the laser helps to weld materials with a high melting temperature, exceeding 5500 degrees Celsius.
It even joins those materials that could not be welded in any other way.
It is a very fast and highly productive welding process.
