Arc Welding Apparatus TRIZ Cases

Wave-shape state segmentation weights weld parameter deviations in real time to detect defects and quantify arc weld stability.

A laser heats one offset component while an arc welds the joint, achieving full penetration on thicker parts without adaptive control.

A modified AC welding waveform raises cryogenic toughness in stainless steel welds while enabling lower-cost electrodes and higher deposition rates.

A bell-shaped reinforcing sleeve strengthens welded-lap steel pipe joints, reducing stress concentration and delaying buckling under compressive loads.

Alternating high- and low-heat arc periods cuts burn through and strain in thin sheet welding while keeping the arc stable at high speed.

An oscillating coil detects welding wire diameter and composition from damping and frequency shifts, improving weld setup accuracy and safety.

An OCT-based optical setup tracks weld keyhole depth in real time, replacing destructive seam testing and enabling immediate penetration control.

Controlled electrode Cr, Mn, and Si with Ar-CO2-O2 shielding cuts slag while improving fatigue and corrosion resistance in 780 MPa steel welds.

A driven pin is welded to the metal layer to create stable joints that resist shear and pull-out in metal-composite assemblies.

Fusion welding dissolves SiC or B4C into iron-based hardfacing to deliver uniform hardness, lower density, and better impact and sliding wear resistance.

A tilted protective surface redirects ablated coating away from precoated steel sheets, reducing weld-zone build-up and tracking errors.

Sequencing short-circuit, pulse, and zero-current cooling periods reduces spatter and stabilizes heat input for uniform scaly bead geometry.

Remote reset circuitry restarts welding machine processors without shutting down power conversion, cutting downtime and component stress.

Automated operator and workpiece identification switches welding schedules and settings to cut errors in complex semi-automatic weld cells.

Continuous DC-AC transition with adjustable AC balance keeps the weld puddle fluid, reduces arc blow, and avoids chamfering.

A secondary fusion weld on the first weld toe alters anodic phases, improving 7xxx aluminum joint corrosion resistance without FSP.

Low-silicon flux-cored electrode chemistry uses zirconium, aluminum, and boron to refine weld structure and improve low-temperature toughness.

Stored energy is charged between welds and discharged during welding to boost output beyond supply rating without system reconfiguration.

A cloud welding platform stores and trades process data to improve remote monitoring, quality control, and resource sharing across sites.

Alternating high and low heat input periods keeps short-circuit arc welding stable on thin sheet while reducing burn through, strain, and undercut.

Constant hot-wire feeding stabilizes arc ignition before cold-wire addition, improving weld quality and heat input consistency.

Controllable switches route welding power to only the selected process terminal, avoiding hot unused outputs and manual cable changes.

Upstream gap sensing and angular probe adjustment help position weld material accurately in narrow, curved joints with steep edges.
