Interpretation Introduction

Interpretation:

Thetechniques that would make easy welding of aluminum and some designations of readily weldable alloy needs to be explained.

Concept Introduction:

At the beginning the welding of aluminum is difficult. The process starts after removing the film of aluminum oxide from the surface. If this precaution is not done, small particles of un-melted oxide will get trap in the weld pool that may lead to a reduction of ductility and lack of fusion. In addition, thiscan cause cracks at the weld. Another reason for its difficulty in welding is its soft nature.
