Electron Beam Welding Apparatus TRIZ Cases
- Differentially Pumped UHV Chamber Bakeout Without Gate Valves
A removable UHV chamber enables ex-situ bakeout with differential pumping, faster water desorption, and no costly gate valves.
- Electron Beam Weld Slope-Out for Keyhole-Free Thick Sections
A slope-out electron beam weld overlaps the end of the seam, shifts focus, and closes terminal keyholes in thick-section joints.
- Localized Vacuum Sealing for On-Site Thick-Wall Laser Welding
Sealing plates create a local vacuum inside thick-walled pipes, enabling deep on-site laser welds without a large transportable chamber.
- Electron Beam Pulse Control for Precise Small Bore Drilling
Pulsed electron beam parameter changes shape small deep bores faster, improving geometry control, surface quality, and melt expulsion.
- Electron Beam Weld X-Ray Monitoring for 3D Defect Detection
Dual orthogonal X-ray sources synchronized with the electron beam enable real-time 3D weld imaging for penetration and porosity detection.
- Sealed Cavity Structure Assembly to Prevent Diffusion Welding Deformation
Vacuum perimeter welding plus hot isostatic diffusion bonding forms complex sealed cavities while limiting hollow-section deformation and misalignment.
- Gas Cluster Ion Beam Pulse Switching for Precision Trimming
High-voltage pulse switching enables fast rise and fall times in gas cluster ion beams, improving trimming accuracy and throughput.
- Power Beam Welding of Ni-Based Superalloys to Prevent Cracking
Longitudinal power beam oscillation uniformly melts Ni-based superalloys and slows solidification to reduce weld cracking and process time.
- Vacuum Laser Welding Chamber With Movable Gap Covering
A movable gap-covering chamber maintains vacuum over large workpieces, enabling long laser welds with less spatter, porosity, and energy use.
- Electron Beam Weld Rastering for Microstructure Control
A split beam with a fusion spot inside a pre/post heat ring controls cooling rates in EB welding while preserving high joining speed.
- HIGH-THROUGHPUT PREPARATION METHOD OF (Sm,T)(Fe,M)12 ALLOY BASED ON DIFFUSION MULTIPLE
A diffusion multiple combines metal strips for parallel Sm-Fe-12 alloy screening, cutting experiment time while improving phase stability.
- Composite Sandwich Structure Welding for High-Temperature Bonding
Temporary supports enable welding of undulating sandwich cores, replacing braze joints that fail at high temperatures while preserving strength and low weight.
- Cavity Structure Assembly Using Vacuum Welding and HIP Bonding
Vacuum welding around recessed substrate areas, followed by HIP diffusion bonding, forms tight cavity structures without channel deformation.
- TWIP Steel Electron Beam Welding for Narrow Heat-Affected Joints
Vacuum electron beam welding uses preheating, tack welding, and deep penetration to preserve TWIP steel joint strength and plasticity.
- Mobile Vacuum Chamber Welding with Dual Pressure Zones
Dual vacuum chambers maintain a pressure differential to block air infiltration, stabilize the melt pool, and weld thick parts without zero-gap sealing.
- Metal Packer Weld Joint Using Nickel Shim for Expansion Reliability
A nickel-base shim consumed by electron beam welding prevents brittle martensite in dissimilar steel packer joints under expansion.
- Internal-Space Weld Layout to Prevent Cracking in Aluminum Joints
Laser or electron beam weld paths are arranged around internal spaces to simplify multi-spot joining and prevent cracking while preserving sealing.
- Steel-Aluminum Spot Welding with Two-Stage Nugget Formation
A two-stage energization sequence joins steel to aluminum by heat transfer, suppressing spatter and adhesion while preserving sheet thickness.
