I have just spoken to our technical engineer and he confirms that he carried out the tensile test this morning, detail of which follow.
To confirm 1.1 Tensile strength after welding.
Material was tensile tested with two welds in the sample length, photograph of the result attached. The tensile strength monitored for the rod to fail = 26.2Kg/mm² (257N/mm²). As you can see the welds remain intact.
If you follow the You Tube link below you can view a similar material being cold welded on a Autoweld 1320 machine which is just a larger version of the AW813 that this material was welded on.
