'Recognizing the need is the primary condition for design.'
This section of the website covers a number of essential elements that need to be considered and understood inorder to complete your welding module.
LA A - Properties and behaviours of welded materials
LA B - Examine weldable materials and thier behaviour during the welding process
LA C - Carry out practical welding skills safety to join metallic materials togeather
When testing welded materials for defects there are two main types of test that can be carried out. Destructive (breaking the weld appart) and Non-Destructive (not breaking the weld appart)
Below is a short description of some of the available techniques.
Above are two examples of welding applications for you to use in your writeup for LA A.
1: Tig welded titanium bike frame
2: Mig welded lap joins for a leg housing / retainer

Resistance welding is conducted as follows:
Apply force and current through electrodes in contact with metal parts to be welded; resistance heat is generated at the interface of metal parts and makes a nugget, resulting in melt joint.
Though a large current flows, there is no danger of an electric shock because only low voltage is impressed.
