摘要： A gas-shielded arc welding method is disclosed and includes joining steel materials together by narrow-gap multilayer welding. A groove between the steel materials has an groove angle θ of 20° or less, and a root gap G (mm) that is a gap at a lower portion of the groove is 7 to 15 mm. Root pass is performed in one pass using a ceramic-made backing material at a welding current I (A) of 250 to 400 A and a welding voltage V (V) of 25 to 45 V while a value [Q/G] obtained by dividing a welding heat input Q (KJ/mm) computed using a prescribed formula by the root gap G (mm) is controlled within a range of 0.32 to 0.70.

摘要： The electronic regulating system for protective gas flow applied to welding equipment with connectivity interface, the subject of this invention, comprises regulating equipment (100) for gas flow equipped with a system that monitors parameter data in real-time. These parameters include open arc time, utilized gas flow, gas volume, electric current, electric voltage, wire feed speed, and total accumulated wire. The monitoring, process control, data storage, and production tracking are performed entirely online. The regulating equipment (100) consists of an electronic board (10) for data processing and a set of sensors that read the relevant process variables, sending signals to the equipment's process microcontroller.

摘要： Some examples of the present disclosure relate to a cover cap for a welding torch. The cover cap is attached to a housing of the welding torch and rotatable between a closed position, where the cover cap covers an access port of the welding torch, and an open position, where the cover cap does not cover the access port. The welding torch may have welding components within the handle that may be accessed through the access port when the cover cap is in the open position. A cap holder may be used to hold the cover cap in the open position.

摘要： A method for manufacturing a stator in the related art has a problem that the size of a stator cannot be sufficiently reduced. A method for manufacturing a stator according to the present disclosure includes: a welding end holding process of holding, by welding clamps, a coil end that is one end of wiring composing each of the coils and another wiring different from that of the coil; an electrode end holding process of holding an energizing position provided in the other wiring by a conductive electrode clamp; and a welding process of energizing the electrode clamp, and joining the coil end and the other wiring clamped by the welding clamps to each other by the TIG welding.

摘要： The present disclosure is directed to systems and methods for pretreating a wire that is used in a welding operation to reduce the amount of hydrogen introduced into a weld. Using embodiments of the systems and methods disclosed herein, one passes a wire through a pre-treatment chamber in which a wire is treated to release hydrogen and/or other contaminants, and provides a gas flow through the pre-treatment chamber so that the contaminants that are released from the wire are taken up by the gas. The gas exiting the pre-treatment chamber may be isolated from the shielding gas utilized during a welding operation. For instance, the pretreatment gas may be directed away from the distal end of the welding torch, thereby preventing released contaminants from being transported into a weld.

摘要： A method for using a plasma torch includes delivering a plasma gas through a plasma gas flow channel of a plasma torch while ionizing the plasma gas to produce a plasma arc that extends between the electrode and the workpiece. Additionally, shield fluid is delivered through a shield flow channel at a first pressure. A piercing operation to produce a pierce hole in the workpiece using the plasma arc is initiated while the shield fluid is delivered through the shield flow channel at the first pressure. After conducting the piercing operation for an amount of time, the shield fluid is delivered to the shield flow channel at a second pressure that is higher than the first pressure. Subsequent to the piercing operation, performing a cutting operation that forms a cut in the workpiece that originates at and extends away from a boundary of the pierce hole.
