Welding Procedure for Aluminum
Welding aluminum can be a challenge, even for welders experienced in other metals as aluminum has quite different properties than other metals used in welding. It has a lower melting point higher thermal conductivity than steel and this can lead to burn though if the correct techniques are not used. Aluminum wire is also softer [...]
MIG Welder Operation
Metal Inert Gas or MIG welders use a consumable wire feed electrode that provides molten metal for the joint. Lincoln MIG welders and Miller MIG welders use this method.Heat is generated in the process between the electrode and the work metal. A spatter of hot particles is produced in this process which make it difficult [...]
TIG Welder Operation
Tungsten Inert Gas welders or TIG welders use an inert tungsten electrode and heat is generated between this electrode and the work metal. Miller TIG welders and Lincoln TIG welders both operate using this method. It was first used in the aerospace industry in the 1940’s
It can be used in two ways either without [...]
Arc Welding - the Basics
One method of welding used by both Miller welders and Lincoln welders is arc welding.
Arc welding is a process for joining metals by fusion. Intense heat is applied to two pieces of metal causing either the metal itself, or a filler metal, to melt and hence fuse the two parts together, Once cooled the [...]
