Abstract
A B S T R A C T
A backing support strip to aid in the welding of metal sheets, the strip having a body portion forming part of the sheets, a projection extending from the body portion, which projection receives a strip of weld resistant material, which strip is to be located adjacent abutting edges of the strip.
A backing support strip to aid in the welding of metal sheets, the strip having a body portion forming part of the sheets, a projection extending from the body portion, which projection receives a strip of weld resistant material, which strip is to be located adjacent abutting edges of the strip.
Description
The present invention relates -to welding methods and more part-icularly but not exclusively to me-thods of welding metal sheet to be used in the manufacture of storage tanks.
In the manufacture of tanks as used for the road transportation of bulk liquid, the tank is manufactured from a single sheet of metal, usually aluminium alloy. The sheet is formed around shaped ends until its longitudinal ends meet. These longitudinal edges are welded together and the shaped ends welded to the sheet to form the tank. Subsequently fittings such as support rails are welded to the formed tank. This method of construction is generally time consuming and expensive, while also not making the most efficient use of materials.
It is the object of the present invention to overcome or substantially ameliorate the above disadvantages.
There is disclosed herein an extruded metal strip having longit-udinal sides adapted to be welded to an adjacent strip of metal abutting one of the sides, the strip having a main body portion with the one side, a backing support portion formed integral with the body portion so as to be joined thereto by a longitudinal rupturable web, the web having a variable thickness so as to have a longitudinally extended groove along which the web rup-tures, the support portion having a longitudinal recess to receive a backing strip for the weld to be formed on the one side, the recess being substantially co-extensive with the one side and extending laterally on both sides thereof so that a backing strip located therein will prevent the support portion being welded to the main body portion thus enabling the removal of the support portion and backing strip upon completion.
There is also disclosed herein a backing support strip to be removably attached to abutting edges of a metal sheet or sheets, said support strip having a longitudinal recess to extend adjacently along and laterally of said edges.
~_~ - 2 -4~)5 A preferred form of the present invention will now be disclosed by way of example with reference to the accompany-ing drawings;
Fig.l i~ a section of a longitudinal extruded member to be provided as a joining member between two sheetQ of alu-minium alloy; and Fig.2 is a section of a longitudinal strip to be used as a bacXing me~ber when joining two sheets of alu~inium alloy.
With reference to Fig.l, the section 10 of extruded aluminium alloy is provided between two sheets 11 and 12 of aluminium alloy. The sheets 11 and 12 are to be structurally joined by ea~h being welded, by mean~ of welds 13 and 14, to the section 10. The section 10 includes backing supports 15 attached to the main body portion 16 of the section 10 by a fracturable web 17 of redu~ed cross section. Each of the backing supports 15 defines a recess 18 to receive a backing strip 19 preferably of bras~ or copper 90 that tho welds 13 and 14 do not adhere to the strip 19. The web 17 is provided so that the backing support 15 and backing strip 19 are easily removed by fracture of the web 17. Tho strip is provided with a reces~ 26 to allow correct formation of the weld 13.
With reference to Fig. 2 there i8 provided a backing support strip 20 to be used in the joining of sheets 21 and 22 by the appl~cation of a weld to the opening 23. The strip 20 has a recess 24 to recoive backing strip 25 which i8 pre-feribly of a diorent material to that of the ~h~et~ 21 and 22 ~o that the strip 25 does not adher~ to the ~heet~ 21 and 22. The strip 25 i9 providod with ~ re~ 27 to allow tho corr~ct ~or~atlon of ~o-w~lL
Using the abo~e discussed ,~e~hod and ~ectionR in the ~anufactuxe of ~torage tanks the ~ection 10 pro~ides a ~ount-ing for the tank on a vehicle to receive the tankO Addition~l sections may he weld~d to the 3heet to provide rails and other fixtures. The strip 20 facilitates the manufacture of any cylindrical stQrage tank which i~ formed from a ~eries of cylindrical section3 joined at their abutting ends by a weld formed with the use of backing ~tr.ip 2~. As an example of the use of the strip 20, it could be secured within the interior of a cylindrical tank to be manufactured from two or more cylindrical sections~ Two section~ 21 and 22 could be placed in an end abutting relationship and strip 20 located on the interior and extending around the join. The ~trip i5 then pressed radially outwardly to maintain the section in axial alignment .
