From oxygen sensors and pressure pumps to motors and battery packs, every component of a ventilator requires superior welds.
Due to the current COVID-19 pandemic, the production of ventilators has increased significantly to support the exponential increase in the number of people infected with the novel coronavirus. This demand exceeds the production capacity of typical ventilator manufacturers, and so manufacturers who usually produce other products have switched some of their production capacity to meet the increased demand. Some of these manufacturers were already properly equipped for ventilator production, but many have needed to adapt and add to their existing machinery.
A ventilator has several major components: oxygen sensors, pressure pumps, motors and a battery pack. Each of these consists of subcomponents, and they are typically manufactured separately and then assembled before being shipped to support patients in ICUs and other hospital settings.
Manufacturers already using advanced welding techniques are typically well placed to switch their production to ventilators, because the components require an extensive amount of welding. The table below lists ventilator components and the types of welding that are used to produce those components.
