Welding Class 6

TERMINOLOGIES IN WELDING

WELDABILITY of Materials

• WELDABILITY = The ability of material to be welded

• GOOD/HIGH WELDABILITY = The ease of the material to be welded using cheaper mean of welding process and simple technique

• FABRICATION WELDABILITY = The ability of the material to have good relationship with the process to produce sound weld and good weld geometry, free from cracks and porosity

• SERVICE WELDABILITY= The ability to produce weld that can sustain thermal and mechanical stresses, corrosion and other service requirement.
  

Example of Weldability of Materials

• GOOD/HIGH WELDABILITY =Mild Steel / Low Carbon Steel

• LOW/POOR WELDABILITY =Medium Carbon Steel, High Carbon Steel, High Alloy Steel, Stainless Steel, Aluminium

Simple kan, sebab itula, bila kita buat kerja welding, harga untuk kerja-kerja welding high carbon steel, stainless steel dan aluminium biasanya mahal dari mild steel. Kerjanya lebih susah dan require special/specified equipment.. :0
