2. Aluminium joining - Wikipedia

   en.wikipedia.org/wiki/Aluminium_joining

   Aluminium alloys are often used due to their high strength-to-weight ratio, corrosion resistance, low cost, high thermal and electrical conductivity.There are a variety of techniques to join aluminium including mechanical fasteners, welding, adhesive bonding, brazing, soldering and friction stir welding (FSW), etc. Various techniques are used based on the cost and strength required for the joint.

3. Welding Procedure Specification - Wikipedia

   en.wikipedia.org/wiki/Welding_Procedure...

   A Welding Procedure Specification (WPS) is a formal document describing welding procedures. It is an internal document used by welding companies to instruct welders (or welding operators) on how to achieve quality production welds that meet all relevant code requirements.

6. Welding - Wikipedia

   en.wikipedia.org/wiki/Welding

   The cost of materials includes the cost of the base and filler material, and the cost of shielding gases. Finally, energy cost depends on arc time and welding power demand. [71] For manual welding methods, labor costs generally make up the vast majority of the total cost. As a result, many cost-saving measures are focused on minimizing ...

7. Weldability - Wikipedia

   en.wikipedia.org/wiki/Weldability

   Aluminium alloys are susceptible to hot cracking, and to combat the problem, welders increase the welding speed to lower the heat input. Preheating reduces the temperature gradient across the weld zone and thus helps reduce hot cracking, but it can reduce the mechanical properties of the base material and should not be used when the base ...

9. Flash welding - Wikipedia

   en.wikipedia.org/wiki/Flash_welding

   Flash welding is also used in the metal building industry to increase the length of the angle iron used to fabricate joists. [1] The aluminum industry uses flash welding to join aluminum, steel, and copper in various current-carrying conductors called busbars. The steel is used for strength, the copper is used for conductivity, and the aluminum ...
