摘要： The present disclosure provides a method for printing at least a portion of a three-dimensional (3D) object adjacent to a support. The method may comprise receiving in computer memory a computational representation of the 3D object. Subsequent to receiving the computational representation of the 3D object, at least one feedstock may be directed through a feeder towards the support. Upon directing the at least one feedstock through the feeder, electrical current may be flowed through the at least one feedstock and into the support. The at least one feedstock may be subjected to Joule heating upon flow of electrical current through the at least one feedstock, which may be sufficient to melt at least a portion of the at least one feedstock. The at least the portion of the at least one feedstock may be deposited adjacent to the support in accordance with the computational representation of the 3D object.

摘要： A spot welding gun for resistance welding of workpieces, includes a base body and a bracket, in which electrode holders are arranged, the electrodes being in turn arranged in the holders. At least one electrode holder is fixed to an actuator that enables the electrode holder fixed thereto with the electrode to be displaced in longitudinal direction towards other electrodes. To protect the electrodes, a winding device with a band is arranged, the band being displaceably arranged between the contact surface of the electrode and the workpiece opposite the electrode. The winding device assigned to the displaceable electrode is connected to the displaceable electrode so that it moves at the same time as the electrode when the electrode is moved in longitudinal direction. The electrode holders and the electrodes have devices for guiding the band from the winding device axially along the electrode holders towards the electrode and vice versa.

摘要： Where can bodies of sheet metal are welded between the welding rollers of a welding machine, the welding current is not applied to the welding rollers until the body is between the welding electrode rollers. In this way, the quality of the weld at the initial weld point is improved, and where intermediate wire electrodes are used, wire breaks are reliably prevented.

摘要： There is provided a method of making a welded can body having a mash seam weld which includes a heat affected zone extending continuously in the longitudinal direction thereof and is formed with no pitting. The weld is formed by mash seam welding a lapped portion of a can body preform made of a surface treated steel sheet while allowing an alternating current to flow through the lapped portion via a water-cooled elongated electrode and a water-cooled rotary electrode. The alternating current has a crest factor satisfying an expression 1.5.ltoreq.Ip/Ie.ltoreq.2.0, where Ie and Ip designate an effective value and a peak value, respectively, of the alternating current.
