摘要： A gas, which flows between a welding device and work pieces while the work pieces are welded together, has large influence on the welding. A sensor device includes a sensor unit and a container that includes a housing case (i.e., housing portion) and a shielding member (i.e., shielding portion). The shielding member is attached to the housing case, and shields radiation heat directed toward the lower surface of the housing case among radiation heat generated while the work pieces W are welded together. The shielding member is inclined with respect to a flow direction of a gas passing through an outlet port for detection of a second gas flow channel so that the gas discharged from the outlet port for detection is blown to the shielding member and thus flows to a side opposite to the side where the work pieces W are to be welded together.

摘要： A GTAW system and a welding method suitable for ultra-narrow gaps, and belongs to the technical field of narrow gap welding. The device includes a argon arc welding machine, a GTAW torch, a welding trolley, a wire feeding device, and a gas protection device. The GTAW torch includes a rotating motor, a rotating tungsten, a conductive system, and a gas supply system. The non-axisymmetric rotating tungsten is drived by the rotating motor through the central rotating shaft. The conductive system is used for connecting and supplying electric power from the argon arc welding machine, and the air supply system is used for providing shielding gas into the welding torch. The GTAW torch is fixed on the welding trolley, and the GTAW torch is moved by the welding trolley, and the wire feeding device moves synchronously with the welding torch.

摘要： A method for preparing an automated welding method for a welding process moves a welding torch with a consumable welding wire during a movement phase at a positioning speed from an actual to a desired start position of a welding seam, and bridges the distance of the welding wire end from the workpiece during a creep phase. The creep phase is at least partially carried out during the movement phase. The wire is moved toward the workpiece at a first specified forward feed speed until a first wire end-workpiece contact is detected, moved away from the workpiece after first contact detection and then recurrently moved away from the workpiece, and the contact is interrupted again upon detection of further contacts, and the movement of the welding wire towards the workpiece and movement away from the workpiece after the contact is repeated until the start position is reached.

摘要： A spool gun having a very unique look, due to its arrangement of features. The spool gun has its wire spool compartment located below the handle and the user's hand, when the user is gripping the spool gun in an operational position. Operably connected to the wire spool compartment is wire spool brake configured to engage with the wire wraps. The brake can have a lock and/or a wire spool life indicator. The wire spool compartment has a cover that is non-threadedly engaged. The feed rate of the wire from the wire spool compartment can be adjusted by a control device, such as a knob, located proximate the user's hand, when the user is gripping the spool gun in the operational position.

摘要： A wire guide conduit is constructed from a coiled wire having an oval or elliptical cross-sectional shape. The wire is subjected to a directed energy beam to locally heat portions of the wire to create discrete areas of increased hardness in the surface of the wire. The wire is coiled to present the locally hardened regions on an inside passageway of the conduit. The wire guide conduit may be used in additional applications such as a control wire for an actuation system.

摘要： An example welding apparatus includes a welding power source configured to output current between a consumable electrode and a workpiece; a feeding apparatus configured to move the consumable electrode toward the workpiece; and circuitry. The circuitry is configured to: control the welding power source to repeat a sequence including: outputting a positive peak current from the workpiece to the consumable electrode during a positive peak period; outputting a first base current between the consumable electrode and the workpiece during a first base period following the positive peak period, an absolute value of the first base current being less than the positive peak current; and outputting a negative peak current from the consumable electrode to the workpiece during a negative peak period following the first base period, an absolute value of the negative peak current being greater than the absolute value of the first base current. The circuitry is further configured to control the feeding apparatus to move the consumable electrode close to the workpiece so as to temporarily short circuit the consumable electrode and the workpiece during the first base period.
