Aluminium Fabrication in Auckland

Otahuhu Engineering knows that aluminium Welding is a fabrication  process that joins metals  together  by  causing coalescence is a welding term,  it is  two or  more  pieces of  metal  where the  joining  points  have been liquified  by  heat  in order to bond them  together, the  liquids coalescers  where they solidify making the  pieces of  metal a  continuous solid. If welded to a  high  standard the  metal will  retain its  original strength. Different metals require  different  conditions to weld,  some require  higher temperatures and  some even require a  pressure to be exerted  along with  the heat. Aluminium welding Auckland provides, aluminium one of the materials  in which the weld ability varies  greatly, this  depends  on the alloys chemical composition. This is  a material  that is  susceptible to a  condition  called  hot cracking;  this is  possible  to overcome  though  by  lowering  the heat  input and  increasing up the welding speed. Preheating is  a method used w
