Introduction

High-productivity welding is an important factor influencing the economics of fabrication of large structures destined for use in the pressure vessel, offshore, and heavy engineering fabrication industries. Electron beam welding is a process that offers significant benefits in terms of productivity increases, as well as repeatability and accuracy in the fabrication of large, heavy wall structures. To date, the use of this process has been limited by the need for a vacuum chamber of appropriate dimensions.

CVE has developed a local vacuum electron beam welding system, which can be readily transported and operated on-site and applied to significantly larger than can be accommodated in a vacuum chamber. Therefore, Ebflow brings all the advantages of electron beam welding to steel structures of unlimited size.

Ebflow facilitates very high joint completion rates in thick-section metals (ferrous and non-ferrous, e.g.: carbon steels, stainless steels, aluminium, titanium) and is 20-30 times faster than conventional submerged arc welding, 200mm per minute in 150mm thick steel has been achieved – allowing for the fastest thick section rates ever.

Ebflow is a local vacuum electron beam welding (EBW) system, which can be readily transported and operated on-site and applied to structures significantly larger than those that can be accommodated in a vacuum chamber.

Ebflow eliminates the need for a vacuum chamber through a local, coarse vacuum, which is established and maintained only where it is needed.

High-performance EBW can take place in any plant where large components are welded on a large scale, as long as adequate shielding from x-rays can be provided.

A system of sliding seals and precision handling enables fast longitudinal and circumferential welds on large workpieces. A coarse vacuum is ideal for thick-section welding – achieving the fastest thick section welding rates ever.

There is no filler wire the autogenous weld can be heat treated and the weld rendered metallurgically indistinguishable from the parent material.

Coarse Vacuum Operation

Ebflow’s differential pumping and RF heated diode gun allow for operation in local vacuum pressure of c.1mbar (high vacuum is 5×10-1-1×10-1mbar).

Precision Robotics

Precision handling of the head of the Ebflow system.

Can be mounted flexibly, e.g.: on circular tracks.

Local Seal

Seals around the welding head create the coarse vacuum.

A box seal is provided for the rear of the weld.

Fast, Flexible Welding

Fast longitudinal and circumferential welds are possible on large workpieces.

The local vacuum nature of Ebflow is particularly suitable for large tubular thick-section material.

Ebflow is 20-30 times faster than conventional arc welding, offering transformational gains in productivity.

It also uses less power than conventional arc welding processes, thereby lowering the carbon footprint.

Among the myriad of other benefits is the ability to perform low-heat input welds that result in reduced distortion – ensuring quality – and the option to perform NDT testing immediately after welding, fast-tracking the manufacturing process, and driving down costs.

 

Lower Carbon Footprint

The energy consumed in one metre of a weld is as much as 75% less using Ebflow than in standard submerged arc welding. In addition  to this there is:

  • Reduced transportation and installation costs
  • No need for filler materials, chamber and associated pumping equipment
  • No pre-heating
  • No loading-unloading operations

 

Greater Productivity
  • Higher speed of manufacture
  • On-site welding
  • No weld joint bevel required
  • Flexibly weld objects of any size
  • No pre-heating required
  • No loading, evacuation and unloading operations
  • Immediate post-weld inspection possible
  • Single-pass welding capability
  • Post weld heat treatment (PWHT) can create a weld rendered metallurgically indistinguishable from the parent material enabling welded components to be used in place of a single forging
Improved Economy
  • Lower working capital requirements
  • Lower personnel costs
  • No chamber and associated pumping equipment
  • Reduced transportation costs
  • No filler materials – lower consumable costs
  • Smaller factory footprint possible
  • The energy consumed in one metre of a weld is 75% less using Ebflow than in the standard submerged arc welding (SAW) process

  • Continuously repeatable high-quality welds
  • Localised residual stresses
  • Weld rendered metallurgically indistinguishable from the parent material
  • Minimal distortion
  • Increased accuracy and repeatability

Turbocharger Electron Beam Welding Machines

CVE’s turbocharger models have been designed specifically for turbochargers, an automotive component that is currently fitted in millions of vehicles across the world.

Electron beam welding joins a cast Inconel wheel and a carbon steel shaft together. The electron beam is a finely focused stream of electrons, which melts the two metal surfaces together, resulting in an excellent quality of weld with the characteristics of:

  • Deep penetration
  • Narrow fusion zone (HAZ)
  • Near parent metal strength

Welding inside a vacuum environment ensures a clean and pure process.

Laser welding in a vacuum is a relatively new technique that has the advantage of two to three times the depth of weld compared with conventional laser welding with shielding gas. It also has the benefits of reduced oxidation and extremely high welding quality.

Laser welding in air leads to a build-up of plasma, which blocks the laser from penetrating the metal, so the beam must traverse the weld joint quickly.

Laser welding in a vacuum can double the penetration, reduce the amount of weld spatter by removing the plasma, and reduce the temperature at which the metal boils allowing deeper beam penetration.

The vacuum chamber provides a ready-made photon containment environment, thereby removing the need for a protected working environment.

CVE’s method of keeping the optical path clean is the key to its success.

  • An increase of over double the welding depth than in air
  • Parallel-sided seams with reduced nail head
  • Increase process stability due to significantly reduced and stable plasma plume
  • Reduction of workpiece contamination by spatter and vaporisation
  • Higher-quality, pore-free weld seams
  • Low operating costs due to efficient solid-state laser
  • Welding process without inert gas

Conventional laser welding is a process that typically occurs at atmospheric pressure, using a shielding gas.

Shield gasses are consumable and are often necessary to protect the weld area from oxygen and water vapour.

As part of the laser welding equipment, we incorporate suitable extraction systems; and compared with electron beam welding, there are no x-rays produced, so it does not require an expensive vacuum chamber.

This also means that productivity can be high, especially where one laser source delivers multiple beams.

Our laser welding machines perform the weld in a protective atmosphere and include a complete work handling package. We can also set up the machine to make the process fully automated.

We offer a variety of laser, optics, and welding heads.
