A shielding gas for MIG or MAG welding of aluminum consists of argon and/or helium containing 300-1000 vol. ppm nitrogen. An Independent claim is also included for a.c. TIG welding of aluminum using the above shielding gas.doi:EP0949040 A1TRUBE STEFAN DR.-ING....
Use that same gas for TIG welding aluminum and you will end up with holes scattered through the weld, known as porosity. One of the first things to always check is the compatibility of the gas with the material. Power Source Not all welders are created equal. One of the main be...
The most common arc welding processes are gas metal arc welding (GMAW), gas tungsten arc welding (GTAW), flux cored arc welding (FCAW), and shielded metal arc welding (SMAW). GMAW, also known as metal inert gas (MIG) welding,uses a continuously fed wire electrode that melts and forms t...
Many MIG welding applications lend themselves to a variety of shielding gas choices. You need to evaluate your welding goals and your welding applications in order to choose the correct one for your specific application. Consider the following as you make your selection: ...
In the TIG and MIG welding of aluminium, high-purity argon or high-purity argon/helium mixtures are used as the inert gas. In order to improve the welding process and the result obtained, the invention proposes that 80 to 250 vpdm, preferably 120 to 180 vpdm, of N2/N2O are added to ...
Improve performance, quality and safety with ARCAL shielding gases for welding The shielding gas you use when welding has a great impact on your final product quality. Inconsistencies in the shielding gas can lead to issues like spatter, oxidation and weld defe...
For MIG welding, either in a spray mode without current modulation or in a pulsed mode, of aluminum and aluminum alloys, with the use of a gas shield for at least part of the welding zone, the gas shield is a gas mixture consisting, by volume, of from 0.01% to 1.80% oxygen and ...
