Question

With the short-circuiting mode of transfer, low currents allow the liquid metal at the electrode tip to be transferred by ____ with the molten weld pool

Answer 1

surface tension

Step-by-step explanation:

Short-circuiting transfer is a mode of metal transfer in welding where low currents are used to allow the liquid metal at the electrode tip to be transferred by surface tension to the molten weld pool. The low current causes the metal to form small droplets that are moved from the electrode tip to the weld pool by the surface tension of the molten metal. This mode of transfer is characterized by a short arc length and a high frequency of droplet formation. It results in a low heat input into the workpiece and a lower probability of weld defects compared to other transfer modes such as spray transfer.
