Introducci\u00f3n<\/strong><\/h2>\n\n\n\n

Welding hardness test<\/strong> is a critical inspection method used to evaluate the mechanical integrity of welded joints. Welding introduces localized heating and cooling that can significantly alter material hardness, especially in the weld metal and heat affected zone.<\/p>\n\n\n\n

If hardness is not properly controlled, welded structures may become brittle, prone to cracking, or susceptible to premature failure. For this reason, welding hardness testing is widely used across construction, pressure vessels, pipelines, automotive, and aerospace industries.<\/p>\n\n\n\n
