Today we received two different requests for help pertaining to shielding gas selection. The first caller requested a chart that tells them what materials can be welded with the different shielding gases that they had. They wanted a chart that can be provided to the welders to make sure they used the right gas on […]
A common question that is asked when manufacturers are trying to determine costs associated with welding is: How many pounds of wire can I deposit per hour? Or, how many pounds of wire can I deposit at a specific amperage or wire feed speed? There are charts to help you determine this, but it’s always […]
Spray is a mode of metal transfer in which a fine spray of metal droplets are projected axially from the tip of the electrode to the work. These droplets are smaller in diameter than the electrode. This mode of transfer is characterized by high wire feed speeds (high amperage), high voltage and consequently high heat […]
The modes of metal transfer refer to the different ways in which the filler metal (electrode) is transferred through the welding arc and into the weld puddle. We can write a book on this topic but we’ll keep it simple to provide an understanding of the different modes of transfer, what they require and what […]
