Support Devices With Shielding TRIZ Cases

Periodic mechanical oscillation stabilizes wire feed and arc formation to join dissimilar metals with lower joint weight and smaller heat affected zones.

A spring-loaded movable collet keeps welding electrodes easy to replace while maintaining clamping force during thermal expansion.

A chambered insert and diffuser sleeve direct shielding gas and cool the contact tip to improve weld purity and reduce welding energy use.

Detent-locked sealing inserts improve shielding gas flow, heat distribution, and consumable life in high-temperature arc welding torches.

Controlled gas flow and resistive wire preheating remove hydrogen before welding while keeping pretreatment gas out of the shielding zone.

Alternating peak and base currents smooth polarity transitions in consumable-electrode welding, stabilizing the arc and reducing droplet scattering.

A pretreatment chamber heats or etches welding wire, then vents hydrogen-laden gas away from shielding flow to reduce weld contamination.

Conical mating contacts and constant pressure cut welding torch breakaway torque, reduce unicable wear, and preserve electrical contact.

A flexible connector with integrated water cooling keeps the nozzle stable, adapts torch angle, and prevents overheating in high-energy welding.

A bypass cooling path and movable shutoff stop water leakage during torch body replacement while keeping coolant circulation running.

A rotatable cover cap and cap holder keep the torch access port covered in use while holding the cap out of the way during maintenance.

An indexed contact tip aligns non-round MIG wire axes to improve electrical contact, weld penetration, and heat affected zone control.

A movable contact tip and 10-20 mm nozzle help prevent spatter buildup, stabilize the arc, and support longer continuous welding.

Complementary tongue-and-groove latching keeps a welding torch cover cap fixed open for maintenance without loss, detachment, or obstruction.

Alternating-polarity ignition pulses improve contactless arc striking on smooth or polished surfaces, reducing misfires and stabilizing weld quality.

Arc-melted refractory wire with reduced volatile impurities cuts sparking, porosity, and cracking while enabling dense 3D metal parts.

Multiple feed wires raise metal 3D printing deposition rate while preserving weld pool stability, uniform deposition, and lower defects.

Multiple tungsten electrodes use polyphase arcs to preheat and clean welding wire, raising deposition rates while limiting heat to the workpiece.

A gas-constricted arc feeds powder or wire through the electrode to prevent nozzle buildup while keeping weld deposition precise and durable.

Dual electrical contacts preheat the welding wire before arc start, improving initiation consistency while reducing arc energy demand.

Arc conductance tracking links welding current and voltage to contact tube wear, enabling timely warnings in robot-assisted welding.

Pressurized gas routed through a torch sleeve clears molten metal during thick-workpiece piercing, reducing top spatter and pierce time.

Continuous wire feed monitoring adjusts current and torch geometry in CMT welding to keep deposition rate and layer thickness stable.

A rotating cover cap with a tongue-groove holder stays attached to the welding torch while securing clear access to internal components.

A rotatable threaded ring lets the GMAW nozzle detach easily, improving gas sealing, spatter removal, and weld quality.

Gaps in a helical torch liner let shielding gas flush wear debris through the nozzle while a seal blocks reverse gas flow and clogging.

A spring-loaded movable collet maintains welding electrode grip during thermal expansion while allowing quick exchange and protrusion adjustment.

Concentric high- and low-pressure shielding gas channels stabilize laminar flow, clear spatter buildup, and improve metal printing run time.

A shared shielding and outer gas path with dual gas lenses shrinks the torch while keeping gas flow stable for cleaner tube weld beads.

Vacuum arc-melted refractory wire removes volatile impurities that cause sparking, porosity, and cracking in dense metal additive parts.

A hinged cover cap with latch and tongue-groove retention keeps the welding torch access port secure while allowing unobstructed maintenance.

An inductive coil and conductive target replace separate switches and potentiometers, reducing dead band and tolerance stack-up in welding control.

A physical model links weaving position to resistance, voltage, or current to calculate weld-line deviation and keep arc tracking stable.

Exchangeable angled nozzle receptacles let one dual-wire welding torch fit different wire alignments while maintaining cooling and gas flow.

A conductive 3D-printed torch head integrates gas, cooling, and wire routing while insulating the filler wire for welding in tight spaces.

Conductive cooling partitions and an insulating holder layer let a narrow-gap TIG torch carry higher current without housing arcs.

A balanced high-chromium weld metal composition preserves creep strength and oxidation resistance in thin-walled steel welds without PWHT.

A balanced 10.75-12% Cr weld metal composition improves creep strength and oxidation resistance in thick-wall arc-welded steel joints.
