ABSTRACT
<p><b>OBJECTIVE</b>To measure the microstructure of laser-welded cast pure titanium by different gap distance.</p><p><b>METHODS</b>Forty specimens were sectioned and welded at four gaps (0.00 mm, 0.25 mm, 0.50 mm and 1.00 mm). Took microhardness test and metallographic examination of welded zone surface.</p><p><b>RESULTS</b>There were no difference in microhardness value and metallographic observation between welded specimens. The width of heat-effected zone was different. The smaller grains and needle-like alphamartensitic structure were found in the heat-affected zone.</p><p><b>CONCLUSION</b>The effects of the joint gap were not significant.</p>
