3.5K views · 103 reactions | Short arc welding takes place with a low heat input when the welding parameters are 50–180 A and 15–23 V. Contact between the filler material and welding piece causes a short circuit. As a result, the tip of the filler wire heats up, and a droplet is transferred to the weld pool. The number of short circuits per second is in the range of 20–200, depending on the welding parameters and the size of the filler wire. | Kemppi | Facebook

2K views · 64 reactions | Globular arc welding is regarded as an intermediate step between short-arc and spray-arc welding. In this method, the parameters are 180–260 A and 23–28 V. In globular arc welding, both short circuit transfer and spray transfer without short circuits are used to transfer the filler material. The large droplets that arise in the transfer of filler material cause excessive spatter. Usually, steps are taken to avoid the globular arc range. | Kemppi | Facebook
