LONGlTUDINAL WELD/NG NEEDS
BODE HSW
The bode HSW range of Seam
Welding machines has been designed for welding longitudinal seams of cylindrical, conical and rectangular workpieces and, in addition, flat sheet or plate.
The robust construction of the machine and patented design of the
clamping finger operatíon ensures the correct alignment for the welding on-gauge material in stainless steel, mild steel, titanium, copper or aluminium. The variable speed travelling carriage which traverses an accurately machined beam ensures the torch follows precisely the welding seam.
The Bode HSW range will produce

Back-up Mandrel
The work is supported by the mandrel wich has a groove to accommodate
interchangeable back-up bar inserts. 
lnterchangeable mandrels can normally be supplíed to handle non-standard diameter workpieces. Flat sheets, cylinders, cones,

The first half of the weld joint ís posítioned overthe back-up ínsert until ít

the first ha1f, the other set of clamping fingers are the brought into operatíon, thus both edges of the workpiece are fírmly clamped together. The workpiece centralísíng jíg ensures that the joint is dírectly over the groove of the back-up insert. The weldíng operation is then carried out by traversíng the torch.
