Aluminium Welding

Holden have a long history of development of welded aluminium products from a wide range of market sectors.  The highly skilled and experience aluminium welders are involved with the customer at the early stages of the design of new products or on established products to value engineer the process to meet customer requirements. 

Scope of work

At Sapa Fabrication our Welding is carried out in accordance with BS EN 1011 parts 1 & 4.

Our Welders are Approved to BS EN 9606-2 to cover the range of Procedure Approvals shown below:

Manual TIG (Process 141) Manual  TIG (Process 141)

  • Combinations of 1000, 3000, 5000 and 6000 Series Alloys.
  • Metal Thicknesses from 1mm to 13 mm for Fillet Welds.
  • Metal Thicknesses from 1.5 mm to 6.5 mm for Butt Welds
  • AlMg ( 5% Magnesium, Type 5 ) and AlSi ( 5% Silicon, Type 4 ) Filler Wires, selected for the appropriate Parent Metal Combination.
  • All Welding Positions except Overhead.

Manual MIG (Process 131) Manual MIG (Process 131)

  • Combinations of 1000, 3000, 5000 and 6000 Series Alloys.
  • Metal Thicknesses from 3mm to 25 mm for Fillet Welds.
  • AlMg ( 5% Magnesium, Type 5 ) and AlSi ( 5% Silicon, Type 4 ) Filler Wires, selected for the appropriate Parent Metal Combination.
  • All Welding Positions except Overhead.


Sapa Fabrication also tailor Weld Procedure and Welder Approvals for Specific Customer Products.

When this is required we can carry out these Procedure Developments and obtain Procedure Approvals to BS EN 15614 -2 or BS EN 15613 ( Pre Production Parts ) and subsequently obtain Welder Approvals to BS 9606-2 to cover this work.

Quality

Sapa Fabrication have Welders Trained to Level 2 in Visual and Penetrant Inspection in accordance with BS EN ISO 9712 through British Institute of None Destructive Testing.

During the production stages the following standards can be applied following development and agreement with customers to meet their requirements:

  • Penetrant Testing to BS EN ISO 3452 – 1.
  • Visual Inspection to BS EN ISO 17637.

Tungsten Inert Gas Coded Welding (TIG Welding)

Tungsten Inert Gas welding uses non-consumable tungsten shielded with an inert gas, to join two aluminium components together. The tungsten electrode provides the charge to create the weld pool, but not the filler, for the welding process. The filler is added as a manual process during the operation. The Aluminium TIG welding process is very clean, with reduced fumes, sparks, and containments producing a more aesthetic weld.

Basic overview of benefits

  • High cosmetic finish due to minimal contamination.
  • Process thin gauge material efficiently
  • High control of process
  • High precision of weld

Metal Inert Gas Aluminium Coded Welding (MIG Welding)

Metal Inert Gas welding process joins two aluminium components together with a consumable wire charged with an electrode current. A wire passes through the welding gun (torch) at the same time as a flow of inert gas. The inert gas shields the weld area and electrode from contaminants.
Basic overview of benefits

  • Comparable low cost solution
  • Higher speed of process
  • Used for difficult to access areas
  • Process heavy gauge material
  • Quick setup time

Welding accreditations:

  • BS EN ISO 9606-2:2004
  • Externally verified customer standards
  • Externally verified internal standards

Products:

  • Automotive, chassis structures, torsion stiffeners
  • Bridges,
  • Pontoons
  • Access units
  • Aircraft seats
  • Ministry of Defense systems
  • Structural Aluminium Welding
