Question

Filler material used in welding should have __________ as compared to the parent metal to be welded.-A-lower melting temperatureB-same melting temperatureC-same compositionD-both &#39;b&#39; &amp; &#39;c&#39;-D-both &#39;b&#39; &amp; &#39;c&#39;

APTITUDE CRACK · Accepted Answer

The correct option is  D both &#39;b&#39; &amp; &#39;c&#39; Filler material used in welding should have both &#39;b&#39; &amp; &#39;c&#39; as compared to the parent metal to be welded: Same melting temperature: The filler material should ideally have a melting temperature close to that of the parent metal. This ensures that the filler metal can be melted and fused with the parent metal during the welding process without significantly altering the metallurgical properties of the joint. Same composition: The composition of the filler material should also be similar to that of the parent metal. This helps in maintaining the desired mechanical properties, chemical composition, and metallurgical characteristics of the welded joint. Using filler material with a similar composition ensures compatibility between the filler metal and the parent metal, resulting in a strong and reliable weld. Therefore, for optimal welding results, the filler material should ideally have the same melting temperature and composition as the parent metal to be welded.
