Alloy Selection

Base metal and filler metal alloy selection is critical to producing good quality welds.  Proper alloy selection can reduce numerous welding problems. Does the aluminum welding you are performing result in significant reductions in tensile strength?  Is the alloy you are using susceptible to cracking?  Does your weld need a post welding heat treatment?  Are your processing parameters appropriate?  Can your yield be improved?  Can your weld quality be improved?
