How To Weld Processes

So start to learn how to weld there are several questions that need to be addressed. To begin we need to determine what metals or alloys we intend to weld and then we are to choose the process and welding machine to use with that process. here we offer a brief description of the main welding processes and the welding equipment we will need.

For the welding of mild steel, stainless steel and aluminum we can choose from three main processes. Arc welding, MIG welding and TIG welding.

Arc welding uses welding rods or welding electrodes as a means of joining metals. This is the most simple and most likely cheapest way to learn how to weld. Arc welding machines are readily available either new or second hand and are most suited for welding mild steel and stainless steel in thicknesses of 1/8th inch and upwards.

Mig welding and MIG welding machines would have to be the most versatile and easiest of the how to weld procedures to master. No need to change electrodes as the machine operates with a wire feed system and employs a spool of welding wire within the machine. Great for welding both sheet metals and heavier steels. Can be used for welding mild steel, stainless steel and aluminum. Great for welding thin metal like on motor vehicle body-work.

mig weldsMig welders generally use shielding gasses s part of the process that can be limiting in outdoor welding applications, however there are gasless welding wires on the market suitable for welding mild steel. Having a small portable mig welding machine that uses gas free welding wire is a most versatile welding machine.

how to tig weldTig welding is a high tech approach to welding. This process takes time to master but will provide the best quality weld for small intricate jobs. Can be used with stainless steel, mild steel and aluminum welding. Tig welding can also be used for many exotic and specialized metals such as gold.

Tig welder machines can be small and compact such as the ‘caddy’ welders that are also capable of stick or arc welding. These machines are often seen on work sites and used by maintenance crews. A most versatile welding machine.
